4.7L Hydraulic Lifter and Valve Cover Gasket Replacement - Tips & Tricks to make it EASY

[@phillanassa759]

Pull the plugs, or use the serpentine belt on, turning the motor by the alternator nut. Spins the motor plugs in or out. With the fan out it's easier and faster to do this job. The time saved pulling the radiator/fan draining the coolant and pulling the heater hoses will make life easier. Former Mopar tech here, did a lot of these under warranty along with 3.7's as well, you can have the job done in under 2 hours and running again removing key components. no sense leaving it all in there and fighting the job, remove as much as possible and go with the flow! Nice job explaining and demonstrating the process of R&R the lash adjusters, and reasoning behind doing this before they fail.

[@dr.oenginerepair6201]

Great advice keep up the great work.

[@phillanassa759]

A first timer with decent tools and some engine experience, 6-8 hours, realistically. I think it took me that long the first couple times, after that, I knew all the shortcuts and got the time down, so I was getting paid 5.5 hours for ~2~ hours of work, Flat Rate. Harry homeowner could do it in a weekend easy I think, with some decent tools, nothing extravagant or special, though there are special tools available for this engine.

@@phillanassa759 how do you take the fan off the 4.7?

[@phillanassa759]

i@@alant7516 Rent or buy a fan clutch removal kit. Other wise, a long skinny punch and a ball peen hammer. Facing the fan from the front end,., put the punch on the left side of the big fan nut. Hit it (the punch with a several pound hammer) counter-clockwise, 1/4 turn and it should come loose, then unscrew it. Shouldn't be tight, 10-15-foot pounds would be a considered almost too tight.

I just finished the valve cover gaskets, lifters (all of mine had no “spring”), spark plugs, and radiator replacement on my wife’s 04 Grand Cherokee Overland and I don’t think I could have done it without your help. I went really slow, though, it took me five days!

These videos are really helpful I’ve having to rebuild a 4.7 that blew its head gasket and I’ve never done this before, but these videos really help not only fix it but also give hints how to make the system better and less prone to breaking

[@larrytate6884]

Priced this through my local mechanic. They wanted $1800.00 to do this. So that's not going to be affordable at all. Watched a few videos (yours is the best btw) All parts delivered to my door from a local supplier was about $120.00. Great video and thanks for taking the time to make it.

[@aztechnology7996]

That 1,800 quote had to be for a new cylinder head all together, along with head gasket, etc. Surely there's no way a lifter replacement would be that much

[@larrytate6884]

@@aztechnology7996 I agree that price was stupidly high. But no it was only for new lifters. To boot as the engine is an over head cam all they had to do was remove the darn valve covers. It was thru Pep boys.

@@BrettWyrick it was a 4 for me. Accessing the lifters from over the fender was difficult (2005 1500 w/2 inch lift, 33 inch tires + Crushed vertebrae from old accident) So I dropped the radiator and cross bar support for it and climbed in the engine bay. All told 5 hours work.

You made it simple, saved money not having to buy a $50.00 tool, thorough instructions, and neat seeing the inside of the the lifter! Great job!

Thanks!

[@jln1122]

I just spin the motor until the cam is not depressing any of the valves and then I just unbolt the cam so it's loose enough to remove and install the rockers without issues

[@dwgleason]

*** This is the way! After buying, fumbling around for hours, and breaking the "special tool", I bent a 10mm wrench as shown (90 deg to get in and 30 deg to clear master cylinder.) It worked so much better! Some notes: 1. 1 full turn of the main will turn your cam about 180. You can get to it from the oil filter hole in the skid plate so you don't need to take the front apart. 2. Work a cylinder at a time, get the lobes pointing upish, pop rocker out, reinstall last one first - it'll save you time. 3. It's easier to just take all the stuff on top off. Yes it takes longer to put it all back but you won't cuss near as much. (2000 Dodge Dakota)

[@charliedee9276]

I put solid adjustable ones in from Airram when I replaced the heads on my 04. Real pain in the ass getting them all just the right size however the very noticeable power increase, especially up top was worth it. No more morning clatter and knowing I won't kick a rocker really made it worth the money and time.

[@majorwedgie8166]

I went through this only to still have the ticking noise. If you have done this procedure and still have ticking problem then do a pressure test on the cylinder that is ticking, not a compression test which will fail on a bad cylinders anyways but you will be able to hear the pressure moving between cylinders via a bad head gasket blown between cylinders. This is what I found on my 4.7

[@Maxxis1941]

So glad you emphasized to soak the lifters. Hint: move the bucket of oil around a few times to move the lifters around. If by chance one is in a position that all the ports aren't accessible to fill with oil, it "reseats" all of them an ensures penetration. Great vid.🤙

[@aztechnology7996]

Nice and informative video. You go into some of the important mechanical theory itself, behind the valve train. Those 4.7's need more regular oil changes and good driving habits (reasonable rpm's, time to warm up in winter, etc). My 06' Commander, 140k miles, I bought for dirt cheap, they said "bad head gasket.".....turned out to be both heads were completely black and sludged oil, burnt valves, 2 dislodged rocker arms, and a few dropped valve seats. Not to mention 2 broken timing chain guides and plugged oil valleys 😂. Was a fun project and saved it from the scrapyard

[@w00derice]

Another trick before doing a hot start: disconnect all the injectors, then crank it over with the starter for about 15 seconds. Wait a minute, then do it again another two times. That way you're positive oil is flowing through all of the lifters and primed properly before the first fire. Did the same thing with my 3.7 and on a ford 4.6 (which is very similar).

[@mr.h.8363]

Man where have you been for many years! Thanks on a GRAND scale!

[@matthewswift5345]

The first time I ever did the VCGs on these 4.7s, it took me over an hour to get all those damn grommets out. lol. Then I found the perfect tool. A 90 degree dirt cheap dental type pick. poke the point into the grommet and rock the angle of the pick against the VCG. it takes 30 seconds to remove them all, AND it can be easily done in the engine bay making the cover so much easier to pass through on the much harder passenger side. Great video btw.

[@benjaminbrown1179]

Bought my 06 ram 1500 and once delivered had 215 miles on it.close to the end of the first year of running it i pulled a camper into the mountains of n.c. for a hunting/fishing trip. All went well and we left. Heading down the grade, in tow haul, i slowed rig and dropped it into 2nd gear to help hold me back. Even keeping it at low speed and mid high rpms i heard a change. Motor had around 25k on it at the time. Got it home, cooled off, and started it up. Been ticking ticky tic tic tic ever since. Itll tic heavy when cold and just starting up. Once the engine gets warm and pressure builds itll stop or just be a light tic. It has been a great audible warning if my oil is getting low as well. Fill it up and it diminishes. I now have 357 thousand miles on her and she is purring strong. Ive always said id do this repair job if it gets any worse. After watching this video itll be done as soon as the parts get here. Good video, and thanks

Very nice video. Covered every aspect of the job and reminded me I should pull plugs and replace them also to save the loss of blood.

So she shut the engine off opened the hood to find oil everywhere and smoke from it pouring on the exhaust manifolds. I grabbed my kiddos and head over to pick her up there is a hole the size of a rocker in the passenger valve cover. Cross your fingers for me 🤞 it only damaged the VC and didn't destroy my Cylinder head. 😂

I appreciate the great explanation of how lifters work and how to tell if they are bad. I have 180k miles on my 06 ram 4.7 and recently blew a head gasket so I pulled the engine and took the heads off to get machined and was told by the Machinist to take off the cams and rocker arms and I wasnt sure about the lifters so I took them out too and most of them have the loose plunger like you were talking about. I didnt know how to test them until viewing this video. Now I know to replace them. Tks!

Great video on a known problem with these engines. I've also seen on of the wheels on the roller followers fail and wipe out a camshaft, while their out it would be worth making sure each of those spin freely. Also on those runner grommets in the valve covers a trim panel popper, the little forked pry bar deal, will grab those and a quick twist rips that grommet right out of there.

I replaced both sides with the felpro gasket and less than a year later it leaks on bottom corner.im thinking of adding copper seal next time

[@mickeyallsopp1321]

Not faulting you, and you do a hell of a good video, just one thing you messed up on. The lifters do not collapse and the springs are not failing. The opposite is true. When a lifter collapses, the internal parts go down all the way to the bottom. These do not. They actually fill up with dirt or sediment and stay all the way extended up. They virtually become a solid lifter. Without the give of the lifter pushing down, that is what makes it possible for the cam to spit the fulcrum out. Aside from that one detail you did a very good job.

[@DEInTheGarage]

Hmm.. That is very interesting and contrary to what I have been taught. I will do some more research on this. Thanks for educating me

[@JF32304]

Cough... Unfortunately I don't think that's the case. You can actually swap these out for solid lifters (martin built has a video) they are not fun but can be done. What causes these to mess up is gunk inside prevents the "cup" from coming back up under spring tension. That same cup has oil pressure under it to push up the rocker and hence open your valve. If you wanted you could take them apart and clean them up and actually revive them. But it's not worth it as a full new set is only a few bucks.

The 4.7 has 3 timing chain tensioner that are hydraulic tensioners the port for these tensioners is microscopic. I would not pour Rotella diesel oil in as it will sludge up and cause issues. I recommend using full synthetic 5w 30 and use seafoam at each oil change. Pour 2 shots of seafoam into oil drive for an hour or two then have it changed while the engine is hot thus allowing all the broken down sludge out before it re-solidifys

[@originalsupermommy]

Spittin a rocker arm 6 years ago is what shut down my '02 Overland. Back then this problem was rare and parts cost twn times what they do today. Eventually as the problem became common with aging 4.7 motors parts got cheaper.

[@fatherguidosarduchi5204]

The lifter and timing chain failures are what have made me a gold mine. I find Grand Cherokees with this problem. People sell them because they can’t afford the garage bill to repair. I buy a nice Grans Cherokee for nothing. Put a little time and money in to it and turn around and sell it for a really nice profit. This is a good engine “IF” you take care of it.

[@tomoconnor7413]

Great video on the lifter replacement. I wanted to add that Martin has a video where he shows an upgrade to the '05 4.7 rocker arm. Smaller oil squirt hole directs oil right onto the cam lobe and rocker roller. Your thoughts on this upgrade?

Yes. I did the “Martin mod” while I was changing out the lifters. I have 237k, about 60k since the change out. So far so good. Supposedly the rockers oil much better than the og arms.

I'm in the process of doing a tear down/refresh of my 4.7 Grand Cherokee. I'm having the heads rebuilt, new stem seals, new intake valve seats as a preventative, and I believe they're putting in remanufactured valves and lifters as well. For $350 a head, that's not too bad IMO. But I find that as I start doing things, I find other things I want to replace, or needs replacing. It's nice to not need to get it done right away, as it's not yet a daily driver (and I work from home 4 out of 5 days a week anyway), but it's crazy how many things pop up lol

Have a 2004 WJ with the 4.7 and 174,000 miles. It has always had 3,000 mile oil changes and all regular maintenance. Its valve cover gaskets do leak a bit, but it never requires any added oil between changes though it does smell bad and occasionally will smoke just a tad from the exhaust manifolds (and this comes out from around the driver headlight). It has never overheated. At this point I am tempted not to mess with it. It has very little cash value as is, and it runs fine (no warning lights or anything abnormal). It was pretty much gifted to me and I have two much newer vehicles to daily drive. What say you? I am afraid I will end up messing something up when it might run another 100,000 miles just fine.

I plan to install a remanned 2008 or newer 4.7HO long block in my 56 Dodge pickup build on my 2001 Dakota chassis. I like the 4.7 engine and Powertrain has addressed all the issues with the 4.7. Also Chrysler updated the heads casting to better support the lash adjusters. My goal is to get near 325hp at the crank. Should give my 56 comparable performance to the Dodge Lil Red Express which was known to be a strong truck.

[@JoshMcGrath98]

Don't waste your time. The 4.7 is not a good engine at all. Go with a 5.7 hemi at least. I'd say go for the 350 gm LS motor. These engines don't last. Mine had to be rebuilt at 155k and I babied it. 3 head gaskets post rebuild too

[@Thisappaintreal]

That is a great plan. I had a Dakota with the NV3500 and the 4.7 and loved that truck. A real good performance gain most guys don’t know is the exhaust on the stock 4.7 loses a good 40 HP due to the Y pipe design, if you run true headers and duals it runs much nicer. AIRRAM has tons of parts than can make the 4.7 make 300 to the wheels NA. If you’re really wanting power you can scower marketplace for an early 2000s SVT blower from a 4.6 and with the help of a aftermarket intake plate it all bolts together kinda nicely. Would be a sweet build and might put you around 350-375 to the wheel

[@Thisappaintreal]

@@JoshMcGrath98you either don’t do maintenance or had bad rebuilds. The 4.7 really only has 2 top end issues that’s it. I’d stay far far away from any GM 5.3 due to the AFM being 🗑️. The 4.7 is a fine engine and is easy to work on. Yes it does require some things dodge should have fixed but it’s much cheaper to work on than the 5.7, also just to price out a swap for this wouldn’t make any sense. You can add a blower to a 4.7 for less than you can slap in tje 5.7 and you’d be probably less on power that way

[@JoshMcGrath98]

@@Thisappaintreal I always did routine maintenance religiously. The vast majority of people dislike the 4.7 so it's just not my build. The rebuild shop did a very good job on the bottom end and rebuilding the head themselves though, I have to give them props as I have 150k on the new motor now. It's currently down cause I need to do a chain tensioner cause I went cheap like an idiot. If it has a head gasket issue again, I don't know what I'm going to do with the truck.

I did not (obviously), but sure. That would be something else to do. I did not as I did not feel like messing with the valves and risking dropping on into the cylinder

[@tradbowhunter53]

Could this cause the intermitten misfire i have? I do have ticking coming from about the valve cover area, started misfiring after i put conventional oil in it due to money issues, since changing the oil back to full synthetic it has gotten better, but still has the occasional miss, swapped plugs, injectors and coils. Still there though. Shop said it could be a valve issue, but that normally would not be intermitten, said the same about piston rings.

I'm about to take on the task of replacing the lifters on my 4.7 as well. Just wondering if mopar lifters are significantly better for them to demand the price as compared to the melling lifters ??

[@DEInTheGarage]

I really do not think so. I certainly trust Melling for in-engine components

[@ocavant]

@@DEInTheGarage fyi, they are not 3 bucks anymore. More like 7 now.

I'm doing a full rebuild, found that a few of my lash adjusters were failing, so I ordered a new set of 16.

This is more of a question I have a 4.7 L V8 in a jeep the 2nd from the back rocker arm was sitting in on the side of the of the head when I go to put it back in I could do it by hand which I know is wrong but would that also cause my motor to seize up to where it won't do a complete 360

[@renejacques8288]

Some people say to use a paperclip to inject oil in the lifters. Are you saying simply soak them for a few hours should do the trick? How do we know the lifters have enough oil, should they be squeechy or rock solid?

[@Dirthauler65]

I know you said if it's a good lifter, you shouldn't be able to push it down with your hands, but I couldn't even push it down in my vise on my bench. Is that right? I would think my vise should be able to push it down shouldn't it?

[@paulallison6689]

Yeah, he got that backwards... They're all plugged up with fine grit & won't compress AT ALL when they're fully stuck like that.

[@pjbj3370]

I found that simply relocating 2 of the long post bolts and move them to the rear 2 bolts, makes it much easier to turn them by fingers down pretty far....

I recently picked up a 06 Grand Cherokee 4.7. Currently has one misfire in Cyl 7, I have replace all plugs/gapped correctly, replaced all coil packs. Ensured injectors are all working. Also have tested to ensure the proper voltage is going to the coil packs/injectors. I do have a slight ticking/knocking sound shortly after starting the car and once slightly revving or driving you can hear this ticking/knocking speed up. I am leaning towards taking the driver side valve cover to see if it is a rocker/lifter issue. Do you think if one of those were to fail it would causing this noise/misfire before I attempt to take the cover of to inspect? Also replaced the EGR valve. My final step after I remove this valve cover is to test compression in Cyl 7.

Thank You for showing the gasket set in the package. When I bought the gaskets they gave me VS 50577 R. The cover gasket was way too thick to fit the groove. I came back and watched this video again to see the part you had. (VR 50521 R) It fits like a glove. Great video. I'll have my 04 Overland back on the road in a few days.

[@flacoooo7001]

I had the same issue next time try a 2003 4.7 valve cover gasket that’s the thinner one but it fit my 2004

[@Kanakid]

Great video. I’m preparing to do this job as well as valve seals on my 04 WJ with H.O.

[@michaelbariso3192]

Mopar oil filters have an anti-drain back check valve built in to hold the oil in the oil pump after shut down that helps prevent hydraulic lifters from falling off. I use full synthetic oil, Hy-Per Lube HPZ212 Zinc Replacement Additive, Lucas oil stabilizer, a half quart of Marvel Mystery Oil and say a prayer with every oil change :-)

[@jonathangomez-vv2dh]

I will do this when replacing my valve cover gasket. Thank you 🙏🏼

[@glenjones3094]

I'm just now coming into problems with my 4.7 jeep and need to chat with the man making this video. Or someone that kinda knows there stuff about these 4.7's. Please see this comment and respond to me. Thanks

[@icenesiswayons9962]

Does the engine when started, refill and pump up the new lifters. When I replaced mine only half pumped up while the others failed and collapsed then never would activate for pressure no matter what I tried, even trying to pump them manually in warm oil. They still would not pump up. All the new liters , when I bought them were flat without oil. I first soaked them in warm oil for 32 hrs, then poured oil in the litter well before inserting the lifters. Changed the oil. And tried a new start. It ran ragged for about a minute then smoothed out. But each time I started afterwards. It did the same thing even smoking from at least 2 cylinders. I pulled the lifters in questions and the had not pumped up. And continued so. I think the 4.7 is a finicky engine to say the least. Every nuance of every part needs to be in top working order for a descent running motor.

[@MrBlunt32]

I have an 07' 4.7L dakota. Having some ticking sound under the covers (used stethoscope). Sound goes away when engine is warmer. Hope it's the lifters! Doesn't seem like a bad job

[@Chris-lo8xs]

You oiled the gasket before installing ! What about the gasket maker sealer do you use that at all ???

[@roncrandall]

You just saved me a complete rebuild.

Glad to hear it!

[@levitezoe1804]

I just bought a 2000 Grand Cherokee Laredo and I hear it ticking sound check all the vacuum lines definitely wasn't any hissing sign definitely was a ticking sound I stumbled across this video and several others confirming on my issue now all I do is ban up and try to see if I can fix this straight six any ideas on performance rocker arms and lifters

[@KyleGreenhow]

Good video, if you take out spark plugs, it will be much easy to rotate, but don't drop anything down those tubes! i messed that up once and had to rebuild my 4.7, so many hours! but it runs great now...

[@swapnifty]

my 2003 4.7 is making knocking sound and I was thinking it was bottom end until I saw this, If its already loose knocking around, could i get away with new lash adjusters or am i going to have to take it somewhere and have them pull the heads?

[@cusco587]

How do you get the gasket to stick in the cover? It will not go in for me

[@josephrodriguez8124]

The rotella oil you’re talking about is it the heavy duty diesel oil?? Idk how likely a response is as this video is 5yrs old lol but worth a shot!

So this is what I have to replace on my 2003 Dodge Ram 1500 with the 4.7L with 268,000 miles that has a "clack clack" noise for about 20 seconds when I first start up the engine?

What do you mean dump the Lucas oil on the cams? How much? Do you calculate how much Lucas oil you’re using and then factor it into how much engine oil to put in for your oil change?

Is it possible for the cylinder to still fire and not throw a code and run fine at low rpm

I had a second set of lifters fail after two months in my 3.7. These engines along with the 3.7 have a slugging problem that causes poor oil pressure to the lifters. I did a complete upper end rebuild, new everything and it lasted 2 months.
