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.

[@kenbritt3805]

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? 😅

[@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 👍

[@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.

[@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. 😊😊😊

[@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!

[@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.

[@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!

[@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.

[@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.

[@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 🙏🏻

[@hhall7152]

Absolutely amazing. Thank you so much. I’m average mechanically but after watching this I’m very confident I can repair my wife’s Caravan.

[@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

[@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.

[@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.

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.

[@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!!

[@hockeyrd99]

Very helpful Robert! I'm not a mechanic, but I'm having this done to my 2014 Jeep Grand Cherokee Limited next week (75K miles). Now I understand what the issue is. In my case I just started getting the P0304 misfire code. No ticking noise that I can hear (I have bad hearing), it drives fine but shakes a little in idle. One mechanic said I needed plugs/coils (that didn't work), then a valve job, a second mechanic said rocker arm/camshaft job. After watching your video, I can see how this makes more sense; meaning a bad rocker causing a misfire. That second mechanic said he's seen this a hundred times. I'm retired, so getting another few more years out of the Jeep would be great.

[@jegg4489]

The tone wheel in the back of the camshaft can get dirty it happened to me I had the same code, I removed the camshaft sensor and cleaned the tone wheels and the code went away

[@linneadarby6925]

May I ask you what you paid for this job ?

[@hockeyrd99]

@@linneadarby6925 The rocker arm job was supposed to be around $3K, but the final price was around $3900 because when they checked out the rocker arms, they were fine, but they found a crack in the head on that side of the motor (revealed by pressure test). The mechanic told me he buys a head "kit" that has all new gaskets and rockers, so that side of my motor is all new now. lol Honestly, I don't have a lot of miles on the jeep, and it was WAY less than buying a new car. I just wish I took my car to the second guy first; they charged me $1200 just to tell me it couldn't be fixed.

[@hectorrivera5390]

Great video, thanks mah man...I appreciate you sharing your knowledge.

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 👍

[@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

[@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.

[@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.

[@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.

[@stevent7783]

Thanks a lot for a very thorough and informative video. It was very helpful with my own project

[@VilleBoyRacingChannel]

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

[@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.

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.

[@user-jp9om5kg1p]

Excellant Video. This is the one to watch to do the job sucessfully.

[@DrTBaginz]

Just bought a used 2018 dodge durango with the 3.6. I changed the oil cooler today and started it up checking for leaks. I am hearing a ticking noise but I'm unsure if it's injectors or a rocker(s) is there a good way to diagnose a rocker going bad?

[@ValleyMobileAutomotive]

Good question. There are a couple things under the hood that make ticking noises. The injectors like you said. There are a lot of them and they all sound the same. The purge solenoid will begin to tick once activated. It sits on top by the intake air duct. You can unplug it to eliminate that noise. A rocker will be a little louder than the injectors and a bit more metallic and deeper sounding than an injector. Hope that helps.

[@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 👍

[@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 👍

[@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.

[@jakobstroud9598]

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

I have a 2019 wk2 with the 3.6 and only just crossed 30k miles. I have a ticking sound that follows the rpms of the engine. I've tried taking it to the dealer but they said they can't do anything since it hasn't thrown a code, which from what I've seen, doesn't happen until there's nearly catastrophic damage to the cam. Sounds like bs to me. Good thing there's awesome people like you showing us how to do it ourselves!

[@ValleyMobileAutomotive]

Yikes! Is it still under your power train warranty? As you know not all engine problems will set a code. They're just giving you the runaround. Sometimes contacting the manufacturer directly with your concern can yield better results.

[@trey6638]

@@ValleyMobileAutomotive Yea the tapping is not incredibly loud, but when the engine is cold and you roll the window down it is clearly audible in the lower 1500-3000rpm range before wind/other noise drown it out. The only thing is that is gets quieter when the engine is at temp and the general noise of the car drowns it out. I told the dealer this and suggested letting the engine cool down to hear it better. So I left them with the vehicle expecting to hear back later or the next day. Nope. Not even 20 minutes after I left, they called me and said they couldn't hear anything and to come pick up my vehicle. I ended up reviewing dashcam footage, and the tech proceeded to take the vehicle right out after I left and floor it down the road and back to the shop. Didn't even bother to open the hood. Sounds like a phone call might be the way to go with it being under warranty.

[@weddinggartersgartersetsga4775]

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.

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.

[@dk3323]

Thanks for the great video! I do have a question. I have a ticking and a misfire on the passenger side (P05). I'm sure I'll find a bad rocker arm. But if the bad follower wore down the outside edges of the cam lobe I'm thinking that won't affect things as the new rocker arm roller will ride on the undamaged part of the cam shaft lobe and not the outside of the scored cam....I think? I'm just trying to save buying a camshaft.

[@ValleyMobileAutomotive]

I understand wanting to save money. When the roller follower fails it stops rolling. Most of the damage to the cam is on the outside of the lobe but there is damage to the whole lobe. As the cam rides on the broken roller it wears metal away from the tip and "flattens" the lobe. This will affect how the valve opens and closes. My advice is to bite the bullet and cry once instead of tearing it back apart down the road.

[@dk3323]

@@ValleyMobileAutomotive You are right....of course! The intake rocker arm on #5 had quite a bit of vertical play, but the roller was still working and is higher than the shoulder, and no apparent damage to the lobe. BUT when I got to #6 on the left side, one rocker arm had some vertical play but the other one was seized and the cam lobe was destroyed. The center of the lobe was ground down with sharp ridges. #6 had thrown a P06 a couple thousand miles ago and didn't reappear after clearing it. I have 24 Melling rockers and lifters arriving tomorrow morning along with the left side intake camshaft. THANK YOU for all the information and giving me the confidence to do this job. The local dealership quoted me $4,998.00.

[@ValleyMobileAutomotive]

@@dk3323 That's great! This is a big job but I think these engines are worth it. I'm glad you're going with a good brand too 👍

[@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 👍

[@twooheightmafia9297]

I’m struggling so bad and I’m not convinced that I’m not making things worse.

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?

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 👍

[@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.

[@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.

[@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

[@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.

[@20irishman]

I’m currently working on this exact problem. Do you have to lock both cams or just one side of cams

[@ValleyMobileAutomotive]

You can just lock the side you are working on 👍

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.

Hi Robert. I just replace rockers and lifters on my 2014 jeep wrangler. I used the tools right the way you did. Put everything back together. And now dont run. The engine sounds like no compression at all. Remove the covers again and the marks in correct position. Any idea?

[@robbsh2s]

Did you figure anything out with this issue?

[@dominiccastro2438]

Hey Robert, why didn't you replace the lifters as well? Trying to tackle this job myself and it was suggested to me to replace the rocker arms, lifters, and cams if they are bad.

[@ValleyMobileAutomotive]

Hey Dominic, good question. These are hydraulic lifters that look like bullets. A pretty stout design. A failing lifter will make a rattle/ticking noise on a cold start up then go away after 2-3 seconds. To check them you squeeze the lifter with your finger. If you can collapse it then it's bad. If it holds firm it's good. If you like you can replace them since you are in there but I haven't come across a bad lifter yet.

[@dominiccastro2438]

Thank you for the clarification. Do you have a source other than the dealer to purchase these? It was suggested to me to go with OEM unless you think aftermarket will hold up as well.

[@ValleyMobileAutomotive]

@@dominiccastro2438 I also recommend OEM. Mopar has updated their design to fix the issue. I would recommend calling the dealer, asking for the parts department. Give them your VIN and tell them what you are looking for. They will give you a price and availability. Then ask for the part number. That will be the updated part. Use that to be sure you are ordering the right part online. There are lots of sites that offer reliable service. This is just one of them www.mymoparparts.com But shop around and choose the site you feel comfortable with 👍

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.

[@evolove8962]

Been working on my charger on weekends when i have time, i changed the rocker arms and lifters and waiting on the right intake camshaft to arrive because the lobes were worn down from driving it with the ticking noise over the years. However i noticed that the right exhaust camshaft with the round plastic on the end of it is slightly cracked and i thought maybe I cracked it when removing the valve cover but it looks like its been cracked for a while.. does it absolutely need to be replaced or can i put it back on since im pretty sure its been cracked for some time now. Also when i was tightening the oil control valve on the left side it moved the camshafts a little bit just 1-3 millimeters at most. Does that really matter? Thanks.

[@ValleyMobileAutomotive]

A cracked camshaft tone ring has the potential to cause issues down the line. You would need to be willing to pull it back apart if it causes a problem. The camshaft moving isn't an issue as long as the phaser is still locked with the dowel pin and the chain is still lined up 👍

According to the manual all the rubber gaskets are reusable. It just depends on how they look when you pull them off. The gaskets you'll be around are the valve cover gasket, intake gaskets, and vvt gaskets. Spark plugs are also optional. They are recommended every 100k miles so if you're close it's a good opportunity.
