How to Install Upgraded Rocker Arms on a Jeep, Dodge 3.7 & 4.7

[@alfonsosalamanca6146]

Greetings Martin, I have a 2003 Jeep Liberty 3.7 and I'm in the process of changing hydraulic lifters as most of them are Not plunging. The Jeep overheated about 6 years ago. I managed to run it once in a while. Anyway, I went to our part store here O'Reilly's ordered some lifters and he told me that they don't stock engine internal parts now a days because, "no one do engine overhaul anymore, they just buy rebuilt engine". I told him that's bs. There are still people who rebuild their engines. So the bottom line, I'm not going back there to buy the rest of lifters and rockers in that store. Thanks for the great tips and videos.

[@donoimdono2702]

the O'Reilly's in Boise stock the lifters... but they're spendy. I bought a set of 16 from rockauto for $70

[@alfonsosalamanca6146]

@donoimdono2702 I actually bought mine from Rockauto.

Thank you, I appreciate that. Stay safe.

[@edgreany4226]

I have had a noisy lifter on my 06 Mitsubishi Raider for over a year. One mechanic said "Oh, that's normal". What he didn't tell me was that it may be "a normal failure" on that vehicle but it still needs replacement. THANK YOU for an excellent classroom education. I'll be back. I wish you were in my town.

You are very welcome.

Man it was so cool watching that camshaft spin. I’m rebuilding my 2004 4.7 after watching all your videos when I get home I need to see what kind a roller rockers I have.

Thanks for putting in the time!

[@linoveiga]

Ok I got some of these upgraded rockers from a 4.7, I see your point and the issue with the original rockers, but I also see that the new rockers created another issue, lack of oil to rocker bearings, I have seen a few videos and the majority of rockers that come off are from the exhaust valves so I’m thinking of installing the upgraded rockers on exhaust valves and leaving the originals for the intake valve as they put out a lot more oil.

[@Thisappaintreal]

Did you have luck doing this?

[@linoveiga]

​@@Thisappaintreal Haven't done it yet, but that is my intension, except I'm doing the upgraded rockers on the Intake valves as they seem to be more common on coming off, hopefully within the next 2-3 months, maybe I will do a video.

Thanks for mentioning what year they were redesigned and what was changed

[@rootbeernineteen135]

The newer ones seem to promote slower leakdown as well.

[@martinbuilt]

Exactly and that is why they should help reduce latch adjuster collapse and the Rocker popping out.

[@thomasvaninwagen2256]

I have a 01 Dodge Dakota it dropped #8 rocker and I don't have compression so It probably dropped the valve. I haven't looked down the plug hole to see how bad. Than you for the video.

[@martinbuilt]

I bet you dropped a valve seat and the valve is hung open and that's why the rocker came off unfortunately you probably gonna have to replace the cylinder head or a machine shop should be able to repair the head.

All of my youtube advice will come from you from now on! (And scotty kilmer lol)

[@IanMcDonald-ro5xm]

PS I popped the rockers in with my tire iron LOL

[@IanMcDonald-ro5xm]

Also to anyone else reading this, probably the rocker kicked off due to poor oil delivery. My suggestion is to replace the worn lifter but also pop off the oil pan and clean the suction filter.

[@JF32304]

The newer ones also increase oil pressure, in doing this it's also putting more pressure on the rocker in turn they won't fall down.

Yes that is my theory as well and was the main reason for installing them. Thank you for watching 👀

[@martinbuilt]

Hi Chris, where did you get the chainset you used and what hardware will I need from the newer engine to complete the conversion?

[@chrisbeitzel4788]

Okay, Rockauto has a Cloyes set #90393SF listed under 2008 dodge Dakota 4.7 for $270.00. This will have everything you will need, except the toner wheel from a 2002 4.7. Grind the rivets from the back side and punch then out enough the remove the toner wheel, Swap the 02 onto the 08 sprocket and weld up the rivets. I spoke with Cloyes about what I was doing and he agreed it would work. And mine is working great. Cloyes has a video on youtube with both applications if you need to watch and see what they did differently. Best of luck.

07 Jeep Liberty, 3.7. My question has to do with the rocker arm and lift shooting through the plastic valve cover today. My question is if the rocker arm wasn't sitting properly or if the lifts with bad could that be the cause?

[@martinbuilt]

If the rocker arm was installed incorrectly, that could happen, but generally, the lifters (lash adjuster) will collapse, causing the rocker to fail out. Then, once that happens, the oil pressure will push the lash adjuster out as well. I have seen several valve covers damaged from the rocker arm. I've never seen one where the lash adjuster goes through the valve cover.

I had a rocker kick off. Valve lash adjuster would not compress at all until I put it in a vice. I put in a new VLA and a new rocker arm, but it had the larger hole. The truck ran great for one month. Now it has kicked a rocker off again. Misfire codes for the same cylinder. Im getting really tired of this engine.

[@Devin_Schwartz]

I'm preparing to replace all of the lifters on the drivers side of my 2001 Dakota with the 4.7L V8. Saw a review which mentioned the 2005 rocker arm redesign, which led me here in an effort to understand the design change and its pros/cons. Excellent video, answered every question I had on the rockers. A few more related questions: 1) Can I rotate the engine via the crankshaft bolt when one or more rockers and lifters are removed, or will doing so cause issues because the exhaust valve(s) will be unable to open? 2) If I replace rocker arms in addition to lifters, do I need to follow any specific break-in procedure for the camshaft upon start-up? 3) What do you recommend in terms of assembly lube? Saturate with oil before reinstalling valve cover, or use assembly lube on the cam lobes? Thanks, Martin!

[@martinbuilt]

I'm glad you like the video and found it helpful.. You can rotate the engine the to where it makes it easy to remove the rockers. Always rotate the engine clockwise when you're facing the engine. There is no need for a break in oil or assembly lube since it is a roller type rocker arm but you can use assembly lube if you like and I would definitely recommend at least squirting some oil over the lobes and rockers before covering them up and make sure you soak the lifters in motor oil for at least several hours to remove the air.

[@Devin_Schwartz]

@@martinbuilt - Thanks, Martin! Appreciate the lubrication tips. What if I want to rotate the engine several revolutions (by hand or via the starter) with one or more rockers removed, would that be alright or cause problems since valves wouldn't be opening? My logic in so doing would be an attempt to ensure the oil passages supplying the lifter bosses are visibly clear and pumping oil before installing new lifters.

[@martinbuilt]

@@Devin_Schwartz Yeah you can rotate the engine with the rockers removed but you're not gonna see oil being pumped through there if you're spinning it by hand, it's gonna take more than that a faster rotation in other words.

[@geostanley409]

I had a bad tapping noise after replacing the number 5 cylinder rocker arm and lifter so I left it alone for several months while trying to find information about the issue. I decided to start it up and move it a couple weeks ago and to my surprise that tapping noise was gone. I’m guessing that the lifter didn’t take on enough oil when I left it in a tub of oil before installation. However, I tried starting it a couple days later and now it won’t start. Now it’s on the back burner again.

i wonder if you would be kind enough to direct me as to how to remove the valve lifters, I bought a valve removal tool from 'autozone but it is too bulky, is there a special tool to this this

[@martinbuilt]

They should come out quite easy by hand if you're having any difficulty at all with them you could probably grab them with a pair of small channel locks or needle nose pliers from the outside edge and lift them out.

Can you provide part number for upgraded rocker and are using OE or aftermarket rocker? Thanks, Mark

[@martinbuilt]

I got mine from pickapart so they are OEM rockers. Here are some links to where you can get new ones if you like. 16 x Rocker Arm 53020742AC 4.7L amzn.to/3prhzt8 Rocker Arm For 99-13 3.7L, 4.7L amzn.to/3rwiM3S Mellings Rocker Arms amzn.to/3pzqpEC

Do you set the timer

[@martinbuilt]

you are not removing any of the timing chains so there is no need to time time the engine, simply remover and replace the rocker arms. Always turn the engine clockwise when facing the engine.

[@anthonyedwards5104]

Is it OK to rotate clockwise to make it easy to remove rocker

[@Rockr69747]

Thanks Martin. My wallet is thinking you're not a nice man, but your content is golden. I'll tell the wallet to quit thinking. Keep that content coming!

Спасибо, Мартин! Очень полезное видео. 👍

[@martinbuilt]

I'm glad you liked it and found it helpful thank you for watching.

[@cobolt13]

How do they just hold on? Once they crack on do they attach to the lash?

[@martinbuilt]

Yes the lash adjuster is holding on to the rocker arm. This is why it's important to have good lash adjusters if a lash adjuster collapses the rocker arm could come out. In my 04 Jeep Grand Cherokee I run solid last adjusters and I don't have to worry about that at all. Other than that they are expensive and you spend a lot of time adjusting them properly.

Hey Mr Martin I have a 02 dodge ram 1500 4.7 motor I just had a Rock arm shoot out of the side of my vele cover on the passenger side and this is my very first truck and I don't know what's wrong but I watch your video on when a Rock arm shoot out of the side what can I do to fix or I have to get another motor

[@martinbuilt]

1st you'll need to remove the valve cover and inspect to see if it damaged the cylinder head or not.. You should find a lifter lifter (lash adjuster) possibly laying in the cylinder head as well. If you're lucky and it did not damage the Camshaft or the cylinder head replace the lash aduster and reinstall the rocker arm. It may be a good idea to replace all of the lash ajusters on that 1 cylinder head while you got the valve cover off. Make sure you soak the new lash adjusters in oil for at least several hours to help remove the air within them.

[@quincyward7187]

I have a picture of it I was I could send to you so you really know what I'm talking about. The thing that pushes the arm up that little slot that thing sit in broke a little pieces is miss it want hold it in place

[@justins8638]

Is it okay to rotate the camshaft, (at the harmonic balancer of course) without rocker arms installed?

[@martinbuilt]

Yes only rotate the camshaft at the harmonic balancer (crankshaft) can be done with or without the rocker arms in place just don't do it at the camshaft cuz this will cause a lot of stress on the timing chain and guides.

[@justins8638]

@ awesome! Thank you so much for your help and your videos 🤙🏻

[@DwightStebner]

Very nice video! I sense a lot of knowledge from Martinbuilt. I see headers installed, curious as to what other performance parts are available for the 3.7? 350000 km on my Liberty, glad I found this video

[@LoudBarkDesigns]

I just bought all new melling 2271 lifters. They compress easily with your thumb. The old are rock solid. No compression. What now?

[@martinbuilt]

you need to soak them in motor oil first

[@LoudBarkDesigns]

@@martinbuilt I did soak them for a bit.

[@martinbuilt]

@@LoudBarkDesigns soak them for a day minimum

[@LoudBarkDesigns]

@@martinbuilt everything is back together. Changed out an injector at the same time that looked rough as the connector portion broke off. Upgraded the lifters and rockers. Running smooth .

[@martinbuilt]

@@LoudBarkDesigns that's awesome, glad to hear that it's running.

[@robertknull456]

Any rockers listed above can be used on a 3.6 ( 2013) Jeep Wrangler?

[@martinbuilt]

The Jeep 3.6 takes a different rocker arm.

[@jjginnard]

Thank You for this video you saved me a ton of work I thought I was going to have to remove the engine head. You videos are so simple to follow.

[@martinbuilt]

Great to hear! Thank you, I appreciate that.

[@gregj.gotham4402]

Martinbuilt: big time shinny looking valve covers look better than chrome. So the new rockers are for a 05 yet fit your 04 correct ! Are they the same for the HO 04 ? I purchased the 04 HO engine to replace my 4.7 broke engine. I will do a total rebuild on the HO im going to replace the rockers with 05 rockers from your link. I’ll purchase all parts needed by your links from now until i get it installed. Including motor mount inserts and transmission mounts.

[@martinbuilt]

Yes the 05 and later rocker arms will fit all 99 through 13 4.7 and 3.7 engines. Thank you for the support I appreciate that every little bit helps. And one of these days I got to get my HO engine rebuilt as well

[@leograjalts]

Good evening, excellent video and explanation, I just wanted to ask you, I have a 3.7 jeep liberty, can I put a 4.7 rock arm and lifter on it without problems?

[@BuiltByRik]

Just ordered from mellings 2 sets part number mr-1345 but they have the bigger holes . This is not good. They have different holes to my old rockers but they are not microscopic like you say yours are?

[@martinbuilt]

Yeah mine are OEM I had higher confidence in the OEM part than I do the aftermarket ones. But the ones you did get are still directing the oil toward the cam lobe instead of just hitting the top of the valve cover and splashing everywhere.

[@BuiltByRik]

@@martinbuilt I have always had a good run with Mellings in the past. I know they cost more but you get what you pay for. Just like the timing set. The quality of this set compared to a generic brand before is noticeably different. I also purchased the professional set. This set is made from Hardened steel and I think only Mellings do a set like that. Other sets are made from powdered steel. They mix different grades of metal powder and heat those up and press them into shape. A much faster and cheaper way of production. Hardened steel is made from a solid piece of steel and then hardened and tempered. I just hope the roller chain will hold up better than the link chain. Rik

[@BuiltByRik]

@@martinbuilt PS yes OEM is better a lot of the time but sometimes a good manufacturer will make a better/improved product. I presumed you had Mellings because you have them in your description.
