Remove & Replace Lifters & Rockers on a 4.7 & 3.7 Jeep Dodge Chrysler & Mitsubishi

[@skn9895]

I have an 09 Dodge Ram 1500 with 330,000 miles on it. I have used full synthetic oil since day one. The lifters started ticking about 10,000 miles ago but I am now finally able to dedicate the time to do this job as this has been my main vehicle and I couldn't afford to let it sit for too long. I hope to get another 50 to 60 thousand miles before I finally trade it off. I've not had to do anything major to the engine, just a couple sets of plugs, a sepentine belt and tensioner, and 3 water pumps. I also had to replace the radiator at about 200k miles. Along with the lifters, I'm replacing the complete timing set, spark plugs and wires, valve cover gaskets, heater hoses, upper and lower radiator hoses and water pump. Maybe I'm sinking too much time and money into something with this many miles, but this has been one of the most trouble-free vehicles I have ever owned, and I have definitely gotten my money's worth on this pickup.

It would be smarter the get new heads at 170k the bearing on cams already toasted so

[@grabitz]

With that motor, the oil journals where the oil comes from to the lifter gets plugged not getting enough oil to the lifter. It's not usually the lifter. Take lifter out. Crank over the motor to blow out the oil journals that are plugged. You will know when the oil squirts and hits the hood so best put a rag over it. Only takes a crank or two to unplug them. Replace the lifter or use a new one. Works every time. It took me 4 times taking mine apart to figure it out with new lifters.

[@UnionThugg]

These are OHC engines, so they don't have "lifters". They're hydraulic valve lash adjusters.

[@richardsmalley122]

You made the rocker arm and lifter look very simple to remove and reinstall. Sometimes I like to work on my own vehicle, dealerships rates are outrageous. Thanks

[@martinbuilt]

yeah, they are easy to replace, the hard part is getting the valve covers off with all the wiring and hoses that are in the way.

[@tylergenke7252]

I just got done doing my lifter on a 2002 dodge ram 1500 4.7 i removed air intake, wire harnesses, radiator hose, disconnected the battery, removed master cylinder from brake drum,and removed brake drum in preparation for this project. Everything went well except the parts store sent a wrong part in place of one of the lifters. i had to go back to the store get the right one and soak in oil for another 12 hours(i cheated and soaked for 8 so i could have it done that day). I used his advice through the whole project and it went well. 2 thumbs up!!! thank for taking your time spent making this video.

[@colerichardson8017]

We bought a 04 Durango with the 4.7, I have the 4.7 in my 04 Ram as well. My Ram runs like a dream, has slight noise on startup but goes away within seconds. It has 201k on it, I got it with 165k. Previously it was a state owned vehicle so had regular maintenance. The Durango on the other hand has about 155k, has significant noise that does not go away. I know these motors are notorious for valvetrain noise due to the valve adjusters getting plugged with crap, but didn’t know how hard it would be to repair. After watching this video I am confident that I can get the job done myself. Thanks for the video, to the point and not a lot of irrelevant talking.

[@daneboyer2164]

Always change your oil on time with full synthetic and try not to constantly romp on the accelerator and you're golden. I have an 03 Durango with the 4.7 and it has been a very reliable engine. 171,000 miles. I've had it for 4 years and the only things I've had to replace were the radiator and the alternator. Now the front end is another story, but that's a just Dodge thing 😂

[@bryanthompson4323]

Thanks Martin for posting this video. My 01 WJ 4.7 had a valve seat come loose about a month ago and I took the heads off and had the machine shop replace all the valve seats. They had a way to install them so that they won't come off again. Well I put the engine back together and it ran great for a few days. Then this morning I went to start it and it made a loud tapping sound followed by an engine miss and a p0303 engine miss code. I had a hunch that a rocker came off and pulled the driver's side valve cover off and there it was. The exhaust rocker fell off. Bought a new lifter for about $13 and popped in like you did and it runs great again. The previous owner wasn't too good about doing regular oil changes and so there was a fair amount of sludge in the engine. I dropped the oil pan and clean the pick up tube and screen as well to be safe. So far so good. Thanks again! Very helpful video.

[@martinbuilt]

I'm glad everything worked out for you. You may want to try some Rislone engine treatment to clean out that sludge.

[@HowardJrFord]

I remember reading someplace awhile back that another problem with these engines is carbon on the valve stems. Supposedly if enough carbon builds on the valve and causes it to stick for even like a fraction of a second, the rocker arm will fall out .

Say Bruh, thank you very much. I thought that I was going to have to, pass out, wake up, and still have to deal with this problem. But then I see you. Smooth, direct, straight to the point. Now I got it. Again, THANKS BRUH. Much Love For You

[@martinbuilt]

You're welcome, the hard part is getting the valve covers off due to all the hoses and wiring harness that run over top of the covers. Once you got them off I think it's pretty easy to change out the lifters

[@somanynamesilltrythis0180]

@@martinbuilt ok that's good to know. I'm hoping replacing the lifters will rid the light color smoke during start up and the engine tick. It goes away after a few minutes but it's definitely bugging me

@@somanynamesilltrythis0180 you didn't mention the light colored smoke on Startup that sounds more like valve guide seals. Now the tick noise your hearing is the lifters.

Maybe not actually lightning quick, but the 4.7 HO’s are definitely not slow. Certainly a lot more power than a JK. Rented a JKU for a week on vacation and I liked the Jeep but missed my 4.7… 😁

I feel like the V8 WJ’s are pretty peppy for a big heavy luxury SUV that was designed primarily for comfort and off road ability. Mine’s just the standard output 4.7L and it’s on 31” tires… while I wouldn’t call it fast per se it’s got enough power to make a fun daily driver. Most of my driving is between 0-45 MPH so I’m happy just being able to easily get ahead of slower traffic without needing to give it a ton of throttle. I hardly ever rev it over 3500 RPM in normal driving, but the few times I’ve ever given it over 3/4 throttle it’s surprised me. Compared to the two high mileage 4.0L XJ Cherokees I daily drove previously, the WJ feels like a rocket, lol. I did do the torque management wire snip and a TransGo shift kit which definitely made it feel more responsive in everyday driving.

[@MotoringAdventures_KE7SAI]

@@TireSlayer55 Nice! Yeah, those are the same reasons I loved my WJ. I actually had my 2008 JKUR for 4.5 years and then downgraded to the 04 WJ Overland because of a job loss AND I secretely wanted V8 power in a solid axle Jeep! It was my first V8 in any vehicle I had owned and I absolutely loved it for what it was! I had a makeshift 2.5" lift from using the "Upcountry Springs" (a mopar accessory for those models) and a 2" Rusty's spacer lift. For shocks, a buddy of mine helped me fab some used JK Rubicon shock take offs to work with the WJ, and that thing handled and rode phenomenal! My dream now is to get a Rubicon 392 which is what I think the best of both worlds (muscle car and Jeep rock crawling). But man I sure did love that thing!

I’m doing this right now on my long weekend . I underestimated getting driver side valve cover off .. it’s a pain in the rear end . But anyways I just wanted to say thank your all the videos that you do . I watched your timing chain video an handful of times before I did mine on my dodge .

[@martinbuilt]

I'm glad you find the content helpful. Thank you for watching.

[@rlarson3232]

I want to give credit where credit is due. I had an extra 10m wrench and bent it in the vise to look like what you had and it worked great!! I used it 100% to remove lifters and 90% of the time to install, at times would have to use a screwdriver to install. I installed 16 lifters got them from Napa, Sealed Power lifters $240 job took about 15hrs ( I took my time and I don't do this as a profession) I reused the OEM valve cover gaskets they looked good and are installed and not leaking. I removed the water reservoir. The right valve cover I loosen the air conditioner condenser on the firewall, I removed the oil pickup and the air conditioner and moved it to the side to give me clearance to remove the valve cover. I soaked the lifters for 30 min in 5-30w and installed lifters and turned over the engine with socket wrench on the flywheel to ensure lifter lob was not depressed. Drove the truck for the past few days and runs great. Thx again for this video

You sir, have made my day. I was just about to buy the tool and was worried about lead time on it (plus the price). I already have a 10mm brake line wrench ready to volunteer. Thanks again.

[@s.adanulloa3902]

Thank you for hosting this video I have to say you removed with it the intimidation out of me to do this. My jeep Liberty with over 300k miles I'm suspecting a lifter got stuck and one of the rockers got knocked over. I saw a video with ame symptoms as mine and I sure hope that's what it is. Have used synthetic oil but last year or so services have been at over 6600 mile if not more. I regreat it now but the damage is done.

[@martinbuilt]

I'm glad to hear the video gives you the confidence to do this yourself. My 01 Dodge Dakota recently passed the 300K mark several months ago. It also has a lash adjuster ticking.

[@phuqueu9237]

Also I have read stories where engine flush gets rid of the ticking sound (some times) and other stories where they tried everything including lifter replacement, and the noise still wouldn't go away.

Coming back to you for your thoughts. Replaced rockers, lifters, and timing set. Still clacking like it’s the lifters... got rid of the initial start up rattle from the chain but after a second of the engine running the clacks come on until it warms up.

did you replace the hydraulic tensioners when you did the timing chain set?

[@isaacsingleton9187]

Very helpful video, thanks for posting this! Surprisingly easy once I got that stupid valve cover off. I have a question though, what if the lobes aren't all pointing up? I just went through this repair and it all went smoothly up until the last two rocker arms. I hadn't thought of that beforehand and I snapped out the rockers and replaced the lifters (which were entirely siezed up, so I know diagnosed it right), but now I cant get two of the rocker arms in. How screwed am I?

[@aztechnology7996]

Question please; I need to rotate the cam (on that same L.H. head as in video), because I'm about to put on timing sprocket and chain, but realized I'd run the valves into a piston. I do know cylinder #1 is @ TDC, so would I be ok with only removing #1 intake and exhaust rockers? I'd figure so since the other pistons are recessed. Thanks

[@CameronDC-Grimes]

I was also taught that having your Jeep WJ run hot (210°F+) on the 4.7L causes the lifters to stick or fail = thousands in repairs. I have altered my cooling system from a hydrolic fan to a Viscous clutch fan with upgraded plastic 11 blade Ford 5.9L fan with slight modifications to clutch face and fan blade bolt holes. I only have an additional 6lbs on the water pump and that causes under 2MPG/3HP loss. Ive been doing fine without the fan shroud with my clutch fan and small E-Fan combo. 12.5" Spal fan that is rated at 2800-CFM and the Severe Duty Clutch fan has over 3650CFM according to my Anemometer

[@Bmanfresh]

So if the cam shaft is in the wrong place? Do we still change it? Or is there a way to move it before you put it back together?

[@RandyCantu]

Hey Martin, what would you recommend I do if I dropped a small bolt down the oil drain within the camshaft case? Right under the rocker.

[@martinbuilt]

I don't think it's going to hurt anything. Most liking sitting on the bottom of the oil pan. You could try to use a magnet through the drain plug to see if you could retrieve it. The bore scope that I have has a magnet attachment that would work well. here is the video on that. kzbin.info/www/bejne/p4eodZJ7gtuHmrM Teslong NTS500 Triple Lens Endoscope amzn.to/35xiHqF

Hello martinbuilt, I have a 2003 Dodge Ram 1500 with the 4.7. I have a CEL that's showing a P0172 code (bank 1 to rich) I've replaced a lot of parts from O2 sensors, fuel pump, fuel injectors, map sensor, IAC valve, intake manifold gasket, a Flowmaster catalytic converter, etc. I've had it to 3 different shops and they can't figure it out. I was told it may be low compression causing it, the lowest dry reading is on cylinder 1 @ 125 and the highest is 140 on cylinder 8. The truck only has 69,000 original miles on it. I bought it in Oct. of 2018 and it's had a CEL on from the time I bought it. I think it was originally a P0138, that's gone now but I've had the P0172 ever since. It won't pass emissions with that code I believe because the CEL is on. Any help would be appreciated, it's either fix it or try to get a waiver if I can. You are very knowledgeable on these engines so I thought maybe you could help me figure this out. Thanks in advance!

[@martinbuilt]

Looks like you have replace most of what I've listed here. P0172 is :system too rich (bank 1). This is usually caused by a restricted/clogged air intake filter. Manifold absolute pressure sensor, throttle position sensor, engine coolant temperature sensor, open thermostat, leaking fuel injectors, failing fuel pressure regulator, failing oxygen sensors.

[@joecalandriello8576]

@@martinbuilt Thanks for the reply Martin, I changed everything you mentioned. I forgot to mention changing the thermostat, engine coolant sensor, throttle position sensor, fuel pressure regulator is part of the fuel pump which is new too.

I could really use some help. I just put new lifters and rocker arms in my 4.7. When I started it, it started perfectly fine, but it had a little bit of a rough idle. No noise no ticking, but it sounds like one cylinder might be dead? I am getting rough fuel out of my exhaust. I’m wondering if I might have screwed up a wire to one of my spark plugs, causing that cylinder to not fire? But I hope I didn’t ruin something in the valve train.

[@martinbuilt]

Did you soak the new lifters in oil to remove the air prior to installing them the reason I asked I'm kind of curious if one of the rocker arms didn't come off on the initial startup.

[@Levers103]

I did, and I started working on it again this morning, and all is good. One of my injector wires had been rubbed past insulation and was grounding out. It caused one of the injectors to stay open while running, and filled my exhaust with raw gas, which smoked pretty bad. Thank you for getting back to me as soon as you did!

[@arronhannah3710]

Hey Martin. Great video. I have a 99 Jeep Grand Cherokee with a 4.7L V8. I have what sounds like a lifter tapping after realizing that I had NO oil in the motor! I had recently purchased it from a guy and I was only over maybe 1000 miles when the vehicle just completely shut down on me driving down the road. It took a few cranks but I got it running long enough to get a mile down the road. I put 4 quarts of oil and some engine restore and some mystery majic? Oil. The tapping slowed a great deal but I still have a tapping when I cold crank in the morning. It subsided shortly after the car is warm but I still here it faintly. I guess my question is, is there anyway to recognize which lifter has the problem without replacing all of them? Would I need to run the motor with the valve cover off? Also, could it just be a loos arm? This will be my first job in this car but I’ve had experience with other motors in the past. Any help would be much appreciated. Keep up the good work my friend!!

[@martinbuilt]

Well you could either use a mechanic stethoscope to narrow it down or a long screwdriver put the handle to your ear and place the screwdriver on the valve cover trying to figure out which lifter may be bad. It's not hard to change them and if you're changing the ones on the right side which is the hardest valve cover to get off you may want to change all of them. Very unlikely that there's anything wrong with the actual rocker arm. Thank you for the nice comment appreciate it

[@arronhannah3710]

martinbuilt thanks for the quick response! I have heard of the screwdriver trick. Unfortunately it sounds like it IS coming from the right side so I will definitely replace them all while I’m in there...since you make it look so easy! 😄 Thanks again!

[@arronhannah3710]

So will the rocker arm fall off of the lifter if it is bad? Or will the rocker arm stay in place? Or will it just be sitting loose inside of the valve cover? Thanks!

[@martinbuilt]

@@arronhannah3710 well there are several things that could happen if the rocker comes off because of a lifter failure. It can just fall off and no damage happen or it can (and most likely will) also shoot-off hit the valve cover knock a hole in it which I have seen before also the lifter may shootout and I've seen where it'll break part of the cylinder head off that holds the lifter in place. Most likely what happens you will end up with some camshaft damage to that lobe it can be ever so slight but it also could end up being bad enough to the camshaft would need to be replaced. This is why I recommend if you have lifters that sound bad that they should be replaced. In any case I would at least change the oil add some Marvel's Mystery Oil or Rislone this could help.

[@tunnelportterror]

if a Dodge engine tosses a rocker arm, you need to change the VALVE SPRING, in addition to the lifter- not just the lifter. the clearance comes from the spring being weak, not following the cam profile tightly and clearance opening up. if you put spacers under the lifter, you will only collapse the spring more and more, and eventually break the spring. change the lifter and spring, it will run fine and not lose rockers.

[@KyleGreenhow]

i just bought new "melling" lifters, but some of them are firm and some are squishy. Is that a problem? (maybe the squishy ones will pump up when i run it the first time?) worried i got some defective ones...

Have replaced all lifters and still the ticking. Is worse when it's very cold out (michigan) but yet after an hour of driving it's still ticking very loud. Every mechanic that has check it out (2004 dakota 4.7) has said it's lifters ticking. What do you think??

[@martinbuilt]

Yes, there is an oil galley. It is possible that they are clogged. One way to check is to remove the lifters (lash adjusters) and plug the spark plugs. Rotate the engine over with the starter until you that oil is coming out of all the lifter bosses. This will force any blockage out.

[@tufaraway]

Should carb cleaner or similar be sprayed into oil holes while the old lifters are out ?

Great video as always. Quick question if you have one bad lifter should you just replace the one or replace all of them?

[@martinbuilt]

On the grand Cherokee if you're replacing the one on the passenger side I would replace all of them because of the difficulty of removing the valve cover if it's on the driver's side which is not too bad and you know which one it is I think I might just replace just the 1.

[@troyonufer2029]

Where did you get the solid lifters from and what's the benefit of going from hydraulic to solid?

[@martinbuilt]

The main reason to run this product is pure and simple... Horsepower. A solid lifter valvetrain is more consistent, opens to a greater extent, and closes faster than a hydraulic setup. This translates into better control of the valvetrain, as well as more duration spent at higher flow valve lifts. In essence, more high rpm power is found by eliminating the physical "collapse" (and resulting power loss) experienced by hydraulic lifters at certain rpm thresholds and valve spring pressure levels. airram.com/product.php?categoryid=19&productid=1416 If you order a set let Nick know that I set you.

What does it mean if you turn the engine over and the rocker keeps falling out?

[@martinbuilt]

If the rocker falls out immediately after replacing it there has to be a mechanical issue as far as a broken valve spring or a collapsed lash adjuster or worst of all would be a dropped valve seat if you can install the rocker without any tools, that is a good indication that the valve seat has dropped and your cylinder head will either need to be repaired or replaced.

Clockwise is best. I have turned it counterclockwise before with no problem.

No as long as you leave the timing chain and cam gear connected to the camshaft there is no need to retime the engine. And remember as you're facing the engine always turn the engine over clockwise and only by the crankshaft do not turn over the engine by the camshaft. Thank you for watching 😊

Hello, back to you for help. As I have commented before on this video, replaced timing components and lash adjusters and I still get the dreaded ticking for a few minutes on cold start. I have a monitor and I recently noticed my oil pressure was stuck, not fluctuating at all. I ended up replacing the pressure sensor and it shows the same thing. This is on a Dodge Ram, these sensors are supposed to give somewhat of an accurate reading correct? I am now thinking I have a blockage in the sensor area limiting oil to the lifters when cold. Common area for sludge to stick? Let me know your thoughts. Thanks.

[@martinbuilt]

I would remove the sensor and temporarily install a mechanical oil pressure gauge to verify the oil pressure. You also use Marvel's Mystery Oil to help clean the engine. Use 5w30 motor oil.

[@ReedBoles]

Thanks for the quick reply. I was running marvels until I noticed it thinned the oil to the point the clacking was more frequent, happening even after letting the truck sit for an hour. I will try reading pressure manually. If that doesn’t show I’m going to try pulling the sensor on the next oil change and cleaning in there with something. I also notice there is a plug to the right of the sensor. Any idea what it’s there for and what size the hex is?

Hi Martin, is there a way to test the hydraulic lifter if it is bad by moving the tip up and down? Most of my lifters have tips that can move up and down by hand, but two are solid. A tow truck driver told me the ones that move are bad, but idk which ones are causing the tapping at start-up.
