Just wanted to give you guys an update. I have a 2015 Jeep Grand Cherokee with the dreaded 3.6L Penstar engine. I started to experience the "ticking" sound a number of months ago and thought it was due to low oil level but after correcting the oil level the problem persisted. I did a lot of research and came across this video. After watching it about 4 times, I decided this was something I could do myself. I called a number of dealership before I started the work to get some quotes. Each one of them told me $5000, 14 hours of labor at $200/hr. $5,000 for this job?! You can purchase and entire use engine for half that! So, I started working on it myself. Upon removing the valve covers, I began to understand the level of damage that bad rocker arms can cause an engine, particularly this Penstar engine. Only 4 or 5 rocker arms were bad but each one had cause damage on all the camshafts. So, after ordering $1400 worth of Mopar parts, I had all new camshafts and all new rocker arms. I installed them per your instructions and when all was said and done turned the car over to hear whether I was successful. I was horrified to hear that that problem was still there. Did I do something wrong? I couldn't have. I followed all the instructions to the letter. Yes, the ticking sound was still there. I drove it around the block and had no inclination that there was anything assembled incorrectly and decided after doing so to take it for a longer ride. When I got back home after an hour ride, I was amazed and delighted to hear the "ticking" sound was COMPLETELY gone and the engine sounded normal again. Thank you sir for an EPIC tutorial and thank you for helping me save $3500! It was an enjoyable experience all the way around. *** NOTES: You can also put a small allen wrench or wire in the top hole of the drivers side chain tensioner to keep it locked in place without having to use the black tool. Also, the 13mm bracket on the drivers side that attached the rear bracket on the air intake underneath has a metal clip on the bolt. To remove it to get at the 13mm bolt, simply work it away from the bolt. It is wrapped around an a/c line but it is not welded. It will twist away from the bolt with some pressure. Other than that, the video was a gift. Stronger recommended! Thank you my friend!!!!!!

[@Howgreat]

Did you buy the special tools (black bone shape bar and the rubber gear locker) to do the repair?

[@MadeinOregon503]

Yes great note on the metal clip around the ac on the drivers side intake manifold brackets. I was confused at first because every video said there was a bolt, but using a pry bar back the clip right off!

[@lucast3006]

I don’t understand why the sound would have still been there after the fix-even if it was transient. I’m trying to wrap my brain around that; the sound should’ve been gone immediately.

[@eddymoney4271]

Do you have a link to where you purchased the parts? Thanks

[@mcalann]

What do you think the initial persistent sound after the repair was due to? 😅

[@micheal7892]

This is a gold standard for repair videos. All needed tools, fastener sizes, and torque specs are mentioned. Wish my automotive teachers had been more like you. Instead, they had us doing one break job and oil change after another.

[@drsauce05]

Just want to come on here and tell that your video tutorial was excellent and gave me the confidence to tackle this job. As of 1 hour ago I road tested my vehicle and everything was completed. Thank you and keep up with the great videos!

[@suzannelambert2059]

EXTREMELY HELPFUL!!! Thank you. My 2015 Grande Cherokee (130,000 mi) repair will be done by an experienced tech as this is in NOOOOOOOOOO manner any of my expertise. I'm amazed at how complicated the initial removal task is and can truly appreciate the effort necessary. This video helps me, the customer, understand why the repair could take a few days in a busy shop regardless if the manual stating the estimated time for a tech. I'm happy to rearrange my schedule to offer as much time as necessary so this repair is done correctly and not rushed. I know how frustrating assembling a flat pack furniture item can be for me. I don't wish that on a mechanic at all. 😊😊😊

[@PMarsVids]

Spot on! Just finished with my 2014 Jeep Grand Cherokee Overland. Found one bad rocker. Still did all rockers, lifters, sparkplugs, and all the gaskets. This video was a LIFE SAVER. Only investement was time, some tools, and parts. Thanks for making this video.

[@ValleyMobileAutomotive]

Awesome! That's a good feeling. Glad this was helpful 👍

[@axelmejia4087]

@@ValleyMobileAutomotivehad a question just finished up putting together the cam and the caps and the timing marks all line up but when I spin the engine right after top dead center there is a little click sound was wondering if that is normal

[@ValleyMobileAutomotive]

@@axelmejia4087 Not sure without hearing it but the chain tensioner could make a click noise or a slightly loose chain could click/slap when turning the engine by hand. The cam is under spring pressure and can kick forward pulling tight on the chain making it slap against the chain guide. As long as you are sure no tools were dropped inside and the timing marks line up you should be good 😅👍

[@peterhudson7540]

To all that are attempting this job, this video is a must! Amazing guide! Thank you so much for this!!! Mine is a 2017 with the gen 2 3.6 so it was a little different. I went ahead and replaced all the cams, lifters, rockers, and spark plugs. Had 1 bad cam and rocker. But had multiple lifters that were questionable. Thanks again

[@ValleyMobileAutomotive]

Hey Peter! Thanks! Glad this video was helpful 👊

[@johngranato2673]

Did you buy the parts at the dealer or is there another source. Thanks

[@snakeshit3088]

Agree 100%- best video out there with all the tips to overcome the “brilliant” engineers that designed this pos. Pathetic Mopar/Jeep didn’t recall this. After my 2017 Grand Cherokee multiple people said, “Oh, you got the Jeep tick”. I’ll never buy another one…

[@CacheMaker89]

@peterhudson7540 I need to do this on my 2018 on the driver side. What exactly did you have to do differently than with the earlier pentastar? Thanks in advance!!

[@Trevorkloida]

Hey man I can’t thank you enough! I did the repair myself my rocker was on driver side exhaust towards the front! I took my time and lots of breaks and was a little under 6 hrs

[@GeorgeMalonedj]

First good job on this repair! If Jeep/Dodge/Chrysler expect to keep clients they need to make it right and recall this issue. It's not the customers fault rather the parts supplier. Unfortunately we know there will not be a recall due to it not killing anyone...

[@88jopar]

Most of these ticking comes from people prolonging their oil and filter changes at 10k miles or doing it at all. If these engines are well maintained, they last an awfully long time as i have experienced. I changed my oil every 4k miles and i never had the tick and i had 250k miles on my 2012 Dgc. I beat hard on it bc it was an Uber taxi, up here on the streets of Toronto and trust me, with all the salt used up here, it causes a lot of potholes. Likewise, i have seen many people who had these engines well maintained and they had very high mileage on them. By contrast, those people who changed the oil and filter by 10 k miles on average or more, had these ticks as early as 20k miles. I have seen these engines tick early even if they are well maimtained about 1 to 2% of the time and just remember, Chrysler has made more than 11 million of these engines and that is why they seem to be a common issue. 1 to 2% out of 11 million engines is 110k to 220k engines that are downright problematic for these pentastar engines. It seems a lot but really it is not.

[@chrisrogers862]

This is one of the best videos that i have seen! Very informative. My exact problem Thank You!!

[@marcsciarrotta3109]

I recently replaced my rocker arms in my 2014 JKU. Now i have a P0349 and C121C. Read somewhere that if you use a telescoping magnet to remove the rocker arms and come in contact with the rear cam sensor pickups and the back side of the camshaft, you could mess up the magnetic pickup tabs??? Do you know anything about this?? My codes wont clear and im stuck in limp mode. Thanks.

[@zackzane944]

I too watched this video a few times and it gave me the confidence I needed to know that I could do this job. I haven't repaired anything on a car in over 15 years, but after watching this video (and a bit from a similar video from MotorCity Mechanic), I cruised through this repair no problem in about 10 hours. Much appreciated!

[@ALTONBENALLY]

Thanks to this video I was able to replace my bank 1 intake camshaft, 2 rockers, and 2 lifters! I ran into a few issues removing the valve cover due to three areas of obstruction. The timing tool kit I bought didn't fit at all, so I did the job without the special tools. My Jeep is a 2018 and my intake camshaft components are also the updated version. The Amazon rocker arms I bought were also different in dimension; rollers were smaller than the OEM. I was lucky that my exhaust rocker arms were all still good. I replaced all lifters on the exhaust side because I found 3 that were failing. On the intake side I only replaced 2 rocker arms and the lifters. Thank you for the video. It was well edited and explained. The breaks also gives you a sense of when it's time for a break during the real job.

[@02mcmurphy]

I have an appointment next week to have my rocker arm replaced. Why wasn’t this a recall? I have 102,500 on my 2015 Jeep Grand Cherokee.

[@LugoDH]

How much did you pay and what exactly was done?

[@rogermadrange1724]

This isn’t so bad of a repair with those special tools. My wife’s grand Cherokee started “ticking”. We took it straight to the dealer to trade it in for a new gladiator. But after watching this, I think I should’ve prob just repaired it. I had already had experience removing the intake manifold to do spark plugs, which is the hardest part of this whole repair.

[@henryhernandez1520]

My sister was about to do the same thing but I convinced her not to. I ended up repairing it up for her just this past weekend. Started Friday and was done Saturday early evening. I did have to replace her left exhaust cam.

[@russell1265]

I think the 3.6 are junk sorry to say I have 2 2015 jeeps same shit along with the oil filter cooler adapter and sway bar disconnect

[@chadwems]

i have to do valve cover gasket at 152k miles on my 2011 grand Cherokee 3.6 . because its leaking oil. AGAIN. and at 145k miles it left me stranded cause the oil filter housing bust open leaking coolant. and it was already leaking oil from that. so 2500$ in repairs in less than 12 months

[@russell1265]

I love jeeps I have had quite a few 150,000 now on the 2 I have probably buy a Toyota next

[@johnagro9981]

Great Video! Used your tutorial and some others to complete the repair. I am extremely grateful for your post on the channel.

[@bobk469]

Thanks Robert!! I'm a decent weekend mechanic but this repair seemed a bit intimidating. My GC (80k miles) had a slight tick, no codes and ran fine. Decided to give this repair a go thanks to your awesome instructions. Ended up having one bad rocker which already started cutting the cam. Replaced all the rockers and lifters with Melling brand. Replaced the damaged cam with OEM Mopar. While everything was apart I did the plugs and PCV valve too. Firing it back up after finishing the job was a scary moment but all good and no more tick! Folks, if you hear a tick, tick, tick you need to get it addressed. Mine had only a slight tick on the passenger side and internal damage was already occurring.

[@dagazenterprise]

did my frinds GC today, slight grazing of the cam lobe. i had to look really hard to see the polishing on the rocker arm.

[@chrisrose5503]

@@dagazenterprisedid you replace the cam? I would assume not.

[@dagazenterprise]

Did this job on my buddies 2012 Cherokee today. I would like to add that the PCV on the passenger side rear must come out, and even with that the valve cover is a bear to get off with the AT dipstick right there. Loosen the bracket behind the cover and swing over towards the center of the engine and the cover will cear. Also, of major importance, after everything was installed, i spun the engine over by hand and for what ever reason, the tensioner on the drivers side, the little saw tooth lock bit did not fully extend, this lead to the chain jumping 2 teeth. After some pondering I figured it out and got the cam aligned. 2 rockers on the passenger side were bad, one was just starting to graze the cam lobe. This video was tremendously helpful. Also, the job took me roughly 8 hours at a steady pace including the hiccups along the way. cheers!

[@LugoDH]

8 hours aye? I can only hope it takes me around the same amount of time lol. Sucks that you can't inspect the rockers until every thing is already off. I have a ticking noise...i hope that it's the rockers lol.

[@mikeorin4655]

Hey Robert, Great video and explanation! Recently had this repair done under extended warranty on 2017 Grand Cherokee Trailhawk with 75,000 miles. If the cam and rockers were found to be destroyed, would you have changed the oil and oil filter as well?

[@ValleyMobileAutomotive]

An oil change should be standard with this repair. Really any time I open up an engine like this I'll recommend an oil change afterward.

[@olvinorellana]

My 2015 grand Cherokee has the ticking sound. I was thinking about doing it myself with a friend but we have no experience.

[@ValleyMobileAutomotive]

@@olvinorellana If you have never worked on an engine before this might be a lot to take on as a first project. But if you do decide to go ahead with the repair I'll try to answer any questions you have along the way. I also have links for the parts and tools in the description 👍

[@tpangle85]

Chrysler really outdid themselves on the 3.6. It's a fabulous piece of shit!

Yea a flaw in the engineering with the rocker arms and they CLAIM to have solved this with the revised rockers on the 2018+ 3.6’s but its the same shit and they failing way sooner than the old design and guess what they are 3 times the damne price @104 each

[@TheBarrios69]

Question, I have a 2012 dodge challenger same pentastar motor, I'm doing the same thing but only on the right side (passenger side) when turning the crank like you did to line up the lines on the timing Actuators and timing chain and mark them. Would my pentastar motor be the same as what you did to line them up? I only have to replace the head gasket on right side ( passenger). Would I line up the same lines as you did on the right side? I have seen other videos done on the left side and as you said people are lining up the Arrows on left side. I really need to know this, before I try this job. Right side Actuators line line up? Not arrows for the right side? Thank you for any help.

Hi can you tell me the exact tools needed to replace the driver side? I’m soon to work on my wife’s jeep and I want to make sure I have everything I need. I’m pretty sure I do minus the torque wrench but just in case could you tell me so I can mark them off?

[@ValleyMobileAutomotive]

@@ScottGroves-yz3yw Sure! I have a list with links in the description 👍

[@scottoswald3771]

Getting a P06de code and was told it could be a misfire code from the oil galley plugs backing off on the front of the head and oil runs back into the timing chain area. Did you notice those were loose when you were in there?

[@ValleyMobileAutomotive]

@@scottoswald3771 This is what my service information says: 1. First verify that it has the proper oil filter. 2. Verify proper oil is used. 3. If the oil and filter does not repair this, check for a leaking o-ring on the oil pump pickup. A borescope may be used through the oil pan drain. If the blue o-ring can be seen, it has slipped out of place. 4. Last resort is a bad oil pump. Hope this is helpful 👍

[@luiszavala9241]

Hey so I had this tick for a while now and I was going to get get it fixed with new rockers lifers and camshafts, and now my engine is quiet ? I pulled into the garage so the mechanic could hear it and it was quiet as a mouse. Any idea on why it’s quiet now?

[@ValleyMobileAutomotive]

It might have worn away so much that the cam is no longer hitting the rocker. Or the rocker has fallen out from underneath the cam.

[@alexng2476]

well I will have to tackle this sometime this summer...my wife's 2015 Jeep Grand Cherokee (110k miles) is ticking on both sides. How long has it been doing...I have no idea so i'm expecting to have to replace the camshafts as well. Now...mopar parts or no?

Awesome video! Helped me out a ton im in the middle of swapping my cams in my 2015 Trailhawk i had a quick question about the little silver lines on the back end of the cam shaft. I noticed on mine it’s almost like some sort of antiseize paste when i touch it but the new ones don’t have it on there. Do you have any idea on what it might be?

[@ValleyMobileAutomotive]

If the silver stuff is on the cam position tone ring then that's from the magnetic ring picking up ultra fine particles from the oil. This is perfectly normal. Eventually the new ones will look like that too 👍

[@LeijaDesigns]

Forgive my ignorance but do the new cams come with new tone rings already installed or did you have to swap them over? Looking into doing this to my 2018 GC. Thank you! @@ValleyMobileAutomotive

[@Nickkkk838]

I'm in a very very bad spot right now. I have the drive side valve cover off, but the passenger side won't come off because the transmission fill tube is behind the valve cover and doesn't allow for enough clearance to pull the valve cover off. Need urgent suggestions if anyone sees this.

[@traviscoomer9247]

I did this fix a week ago and now am having intermittent oil burning smell lasting 10-15 seconds and then going away. Any ideas where it would be coming from no oil on ground.

[@ValleyMobileAutomotive]

Check around the valve cover gaskets for an oil leak. The only thing I can think of that could cause oil burning is if oil is getting on the exhaust somehow.

Do you have to do anything to re-engage the timing tensioner? The one you use the little pick like tool to release. Thanks so much for this video it is truly awesome.

[@ValleyMobileAutomotive]

Good question. Nope just take the tool out, it's spring loaded to get an initial tightness. Once you start it the oil pressure will do the rest 👍

[@peterbarnhardt8573]

Great Video! I am tacking a similar thing because the timing chain guide and a tensioner broke into multiple pieces. i have a 2013 Jeep Wrangler Rubicon and after i replaced the timing chain thinking it would fix the codes, i am still getting codes P000A, P000B, P000C and P000D. I am also getting P00016 Through P00019. I Noticed your magnets on the back of the cam shaft had some silver colored streaks. Mine all have the same thing and when i wiped them off with a soft cloth i was able to pick the cloth up with a magnet! So obviously these were metal shavings. Is that why you have to replace the cam shaft, or were you able to simply clean them up. I noticed you only replaced 1 and not the other 3. Thanks again for the video

[@fritzheer9569]

Hello I have a very important question revolving around the process in your video at 20:10 mark. Your video is great by the way! I perfomed every task, just as you did. The only difference is when i went to perfom the step at 20:10, the wrench pressure was applied and wrench moved 3 violent clicks. Tool went in and nothing appeared upset, so proceeded. Finished putting back together. When i hit the start button for the first time, the engine would turn over very, very quietly, almost like it was just the starter turning. Checked front while had someone hit start, and indeed everything was turning, but no attepmt to start at all. Just very smooth turn over. Almost like no compression at all... What could have those 3 clunks have been that may have damaged something to cause this issues. Could really use your help in piinying me in the right direction. Do you a way i could conact you for a quick chat? Thank you

[@ValleyMobileAutomotive]

Did the timing marks on all the cams line up? I haven't seen this happen but it may be that the chain skipped teeth on the crank. You might need to pull the valve covers off again and check timing.

[@fritzheer9569]

@ValleyMobileAutomotive Very much appreciate you taking the time to reply. Yes. Everything went back together fine. All timing marks lined up, arrows and lines on phasers, dots on cams and phaser flanges. Original issue had the tick, replaced all 24 rockers and lifters with Mopar parts. Had 1 bad Rocker arm, cams are good. I have pulled it back down again to check everything, which seems perfect.... As mentioned, Everything went just as you did in your video identically step by step. That one issue was the only thing different. When the wrench was applied to cam it made 3 pops and moved. The sound it made was like the plastic teeth on special tool holding block had give way, but block tool and teeth were perfectly intact.. clueless at this point and fear putting all back together for same result. Any help is much appreciated. Thank you

About how much a mechanic would charge for this job? Looks expensive

[@ValleyMobileAutomotive]

It's a lot of labor and depending on how many cams get replaced it can add up quickly. I would suggest contacting a couple different shops for pricing and ask if the person working on it is ASE certified.

[@lrod2344]

Why didn’t you align the phasers using the marks on the back and THEN lock them with the tool first? Isn’t that the whole purpose of the tool?

[@danchalmers9774]

Thank you Robert - you are a champion. I did this job for my 2014 Grand Cherokee RHS bank 3 years back but wasn’t aware of the special tool for timing chain. It was a nightmare and could only swap 10 arms and 7 lifters. Didn’t know to crank engine only before firing up so when I did bunch of error codes and lights. Thought I’d stuffed it all. When my LHS started the dreaded tick recently PTSD kicked in and I was calling the Jeep mechanics. $3,500-$4,000 and 2 weeks! A joke. So I manned up and then coming across your tutorial filled in the missing gaps and just finished. All perfect. Is it always the exhaust rocker towards the front that goes? It’s often cited a manufacturing fault in the rocker arm, however to me I think the issue must be the load from exhaust cam/location valve head that causes them to fail. Otherwise not every engine would go (eventually). The downside to that is that even after replacing them once it would imply it will tick again eventually in the future. Might keep my plastic tool.

[@VilleBoyRacingChannel]

Do you have to remove the intake if your only replacing the passenger side ?

if this repair is done correctly, will it reoccur in future. What is your opinion on occurring again with the jeep engine? Is this a defect in the engineering of the engine? Thank you.

[@scottapp4993]

Great video. Thanks. Helped me visualize some things. How come you didn't do the valve lash adjusters/lifters too? Seems they fail too.

[@alexng2476]

Thank you Robert, I just replaced all rockers, lifters and camshafts on a 2015 Grand Cherokee. After pulling out the rockers, to my surprise none were failed but some had lots of side to side play . I also replaced both cam positioning sensors, I’m noticing smoother acceleration now. All in all this video helped me tremendously.

[@McOforis]

You’re awesome. I just did an engine clean with ATS oil system cleaner and changed the oil right after. Before this, the car was very quiet on idle, after the clean and oil change, the car started ticking just like seen in your video. Not entirely sure how a cleaner and oil change might have caused it but I now know the rocker arm is bad. This repair seem intimidating, I don’t have nearly half of the tools you used, but I will give it a shot. Thank you so much for the thorough explanation of everything.

[@charlesosteen8323]

just an FYI the wiper cowling IS removable(had it off in 15 mins after watching a youtube vid) and it makes removing the intake WAYYYYY easier. and since i have the equipment I'm removing the AC lines to make access to the brackets better on the driver side.

[@ValleyMobileAutomotive]

Nice! Yeah being able to remove the cowell would be a game changer with that intake. Could you share a link to the video that helped you out for others to watch?

[@PolakMedic168]

Thank you for your very detailed Jeep Grand Cherokee Rocker Arm video! Not much out there for videos as detailed as yours! I was wondering, were the exhaust rockers different from the intake ones? Im trying to buy some mopar rockers, but one is $78 each and looks slightly different, and the other is $8 with the lash adjuster! Help! Thaks again!

[@ValleyMobileAutomotive]

All 24 rockers should be the same. I would be cautious about purchasing parts from eBay or even Amazon. There have been a number of counterfeit parts circulating that are in legit looking packaging 👍

Coming on with my recent experience with my 2020 Jeep Grand Cherokee 3.6 that’s currently being fixed by the dealership. Not even 3 years old went for your typical oil change on May 10th at the dealership and by Friday my truck was smoking from a blown head gasket, cam shaft seal replacement and bad cylinder, coolant was in the engine from the fail/faulty part. I opened a case with Jeep and the end result is they will be footing 75% of the bill to fix it and their diagnosis result was a failed faulty part…..take a guess what that part was. Total repair cost $4,400 and I was out of the warranty period because my mileage was around 80k, but the open case with Jeep helped me with the cost down. I was told to get rid of the truck, because it may happen again since the 3.6 is know for that issue, but I love my truck. I’m just glad to get it fixed and back on the road again. FYI, my truck never ran hot and it had a slight ticking noise, but it never smoked or had any issues prior to the oil change on May 10th that was a big cause for concern. Also, I had new Mopar Spark Plugs put in early April. I’m still wondering what I could have looked out for prior to this happening, but I never would have thought this would have happened with a vehicle I purchased brand new from the dealership.

[@weddinggartersgartersetsga4775]

Well picked up my Jeep today and I am so happy to have my baby back. It drives like a brand-new Jeep, the slight ticking noise is no longer there. Just pray nothing major happens in the near future, fingers crossed.

[@dylonparma2688]

Can someone please let me know how much this repair may cost at a certified jeep dealer

[@juanitomartinez-sanchez3928]

can you tell me how to remove the right side head cover...? I am having a hard time for it to come off!!! thank you!

[@ValleyMobileAutomotive]

If you have the pcv breather removed from the back and all the bolts are out then you just need to pry up on the cover. The gaskets realy stick on these. Just be careful what you pry on. Sometimes a rubber mallet can break it loose as well. I think I used a combination of both.

[@juanitomartinez-sanchez3928]

@@ValleyMobileAutomotive I tried it. It seems that the small pipe where the pcv was is holding the plastic cover and I am not able to lift it up… also, there is a bracket on the side of it, does that need to come off? Thank you so much!!!

[@Usmcrun97]

I need this done to my to my jeep grand Cherokee where are you located and how much..

[@cloudk2030]

Full time tech here. I got a cyl 5 misfire on same make model and engine. Plugs and coil replaced. No success. Injector next, and if not that, then so you think this job in your video couls be at the end of the rabbit hole for a misfire code

[@ValleyMobileAutomotive]

It's possible. What testing equipment do you have? If you have a pressure transducer you can see a mechanical issue on an oscilloscope. Remember Fuel, Air, Compression, Timing and Spark. That's what you're testing. You already replaced the coil and plugs but is the plug actually firing? How do you know? What makes you think it's the injector? While testing keep in mind that some vehicles will turn the injector off once a misfire is detected to prevent converter damage. You may need to clear the code before testing the injector. I look forward to hearing what you find.

[@bradmoran5762]

I did the last step of break and gas to let it cycle. But now it will not come out of that. Do you know of To make it go back to normal start. I've called the dealership and they are unaware of that trick. Thanks

[@ValleyMobileAutomotive]

There is no trick. Putting your foot on the gas and brake at the same time turns off the injectors. Once you take your foot off the gas and start it normally it will turn back on the injectors automatically and start right up. If your car is not starting normally then something else is the cause.

[@cindirenee]

Best video I have found for this repair 🙌🏻 I have the tension released but don’t have as much slack as you and cannot get my left side exhaust phaser back on. Tension is released but it’s not enough to slip it back on. I’m 800 miles from home and need to button this up to get back on the road 🙏🏻

[@EastMesaUrbanHomestead]

Hello and thank you for making this incredibly helpful video. I noticed that you didn’t have the removal and installation sequence for the cam caps. Can you Ella me out and let me know what they are? I have looked online but see all kinds of different stuff. Thank you in advance.

Here's a link to a Grand Caravan I did that shows the sequence. Removal and installation are the same. kzbin.info/www/bejne/n6bWemaYaq5reNEsi=n0JN-aVM-_UK-eVW Time index 28:40 Hopefully that's helpful 🙂

[@MrBowmanmt]

I have a 2021 Grand Cherokee, so far only 30,000 mi on it and no ticking noise. May I ask the general opinion, is this happening because of the oil filter placement upside down, therefore dry starting?

[@ValleyMobileAutomotive]

Your 2021 will most likely not be affected by this issue (hopefully). There was a period of time when the factory rockers they used were under engineered. Since then their updated parts seem to be holding up.

[@leefritchman9643]

When did they upgrade the parts. I have a 2018?

[@carlosgutierrez6486]

where did you buy the parts at

[@ValleyMobileAutomotive]

A mix of online suppliers. " My Mopar parts" and "rock auto". I recommend sticking with OEM as much as possible.

[@argenisarredondo5722]

[@jt-yf1kv]

How did you get that ac thing off the back 10mm nut on that bottom right side bracket I’m struggling and can’t get a 10mm wrench on it without taking that ac attachment off

[@ValleyMobileAutomotive]

If we're thinking of the same thing that part is the worst. Having a set of flex head ratcheting wrenches to get the nut and stud off and a long pry bar to slide the AC line retainer off the stud.

[@jt-yf1kv]

Thank you so much the pry bar worked perfectly I thought I would mess AC line up but I didn’t thank you once again I appreciate you!!!

What would cause a misfire after performing this work?

[@Wdstack]

Adding my name to the list of satisfied customers. Thank you so much for laying this all out in such detail. This was maybe my first work under the hood and it was a bit daunting. I did the work over three days, and having the video to refer back to was invaluable. My forearms and stomach were getting sore and bruised, and I ended up folding a moving blanket and laying it on the edge of the engine compartment. Made things much more comfortable. Starting it up again and hearing no ticking was such a relief. Thank you so much.

[@mikesdailygaming]

Needing to do this repair on mine just lacking the sack to get it done. Big question I have is who do you use for parts? I usually go to O'Reilly for most of my needs, but I'm not sure if there's a better place to get them cheaper

[@ValleyMobileAutomotive]

Hey Mike, I would go OEM or Melling. I would stay away from cheap. If you are trying to save a few bucks you can get Melling from rockauto.com or OEM from an online supplier 👍

[@chrisrose5503]

When I was trying to reinstall the cam phasers on the right side, i was having trouble seeing the alignment of the shaft to the phasers so I pulled the tensioner release tool out while the cam phasers were off the cams. Now I can’t get the tool back in. Any ideas?

[@chrisrose1508]

After 8 hours of trying to get the cam phasors back on, I'm going to see if I can find a shop that will finish the job for me. I got all the rocker arms replaced and the left (front) side cams back together no problem. The right side (rear) seems to be impossible though since I screwed up and removed the chain tensioner tool before having the cam phasors back on.

[@electricsanti4518]

I have a question my friend, I tried to loosen the exhaust cam bolt while the intake cam was off and the locking tool was in place cus I thought it wont move but it did and the locking tool came off and the cam moved 30 degrees but i returned everything to match markings with succes, do u think i ruined something movin the cam independent of the crank eventhout I was able to align everything back how it was

[@ValleyMobileAutomotive]

The worse case scenario is the chain skipped a tooth on the crank if there was too much slack in the chain. But if everything is lined back up in its original place then you might be ok. When you have the cam all back on and the phaser bolts tight turn the crankshaft two full revolutions then recheck cam timing. If it all lines up you're good to go. If you have any questions feel free to post them 👍

[@sterlingb2003]

I did all the steps in the video to my 2015 dodge durango but after holding the gas and brake and attempting the last step the engine wouldn't turn all the way over. Any suggestions?

[@ValleyMobileAutomotive]

Does the engine turn by hand? I would double check the battery if you haven't already.

[@sterlingb2003]

@ValleyMobileAutomotive the battery seems to be fine. Everything powers up when I press the button however I just went back and checked all connections and realized that the same hose that was broken in your video is also broken in my engine. I believe the purge solenoid hose. Would that keep it from starting?

[@ValleyMobileAutomotive]

@@sterlingb2003 The purge solenoid shouldn't prevent it from starting. Do you mean the engine doesn't spin or it spins but won't start?

I ran into some issues working on my 3.6 in my Jeep JLU. I watched a lot of videos to find out what I was doing wrong and this video is by far the best with pictures of what we need to see along with a quality explanation. After seeing in your engine I ended up figuring out the 3.6 in the Jeep JLU is a little different and requires a different cam phaser tool for the right side.

[@ValleyMobileAutomotive]

Thanks for the heads up for anyone who owns a jeep like yours 👍

Great video thank you!!! I did this over the weekend. I forgot to put back the foam between Intake and valve cover… should I go back and install or leave it out?

I'm not 100% sure what it's for. Maybe a vibration dampener?🤔 An engineer thought it was necessary so I'd recommend reinstalling it 👍

I changed the passenger intake camshaft on my JL and it starts and runs fine but starts misfiring and violently shaking after 30-60 seconds; the CEL light starts flashing and it starts throwing camshaft A/B codes and whatnot. I made sure the timing was correct with the timing marks lined up with cylinder 1 at TDC and 12 pins on the timing chain in between the phasers marks. Any ideas ?
