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

In this video, I'll explain the benefits of the 05 and later rocker arm and show how to install these upgraded rocker arms. This also a great time to replace the lash adjusters (lifters) if there is any lifter tick. Also, show you how they operate with the engine running. With an epic fail but funny.

Still not sure what to get. Your links no longer work. There are several rocker links. Can you update them please?

[@pjbj3370]

Come on bud let see you just POP off the passenger side valve cover.... No just popping off the passenger side, thanks chrysler

[@ImmortalIdeas]

It did for me quite easily. Sure the wire harness is a bit of a challenge. But after studs are cracked loose, it popped with a twist of a flathead.

[@pjbj3370]

@@ImmortalIdeas the actual removal of the cover is easy, it's getting to the cover requiring the removal of basically half the engine compartment that makes it a real pain in the arse

ive got a 3.7 im gonna rebuild, i pulled it because it wouldnt idle,blown head gaskets, and higher miles, and i droped 4 and 6 exhaust rockers what woulda caused that??

[@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.

[@mlubnani]

Great video!!! One question, I changed the Cloyes timing kit and I feel the same tensioner knock noise I had before. Disappears within 2 to 5 minutes of turning on. the oil pressure measured it and it is at 70 cold and at 18 hot idle. I put liqui moly for botadores and I do not improve. What can be?

I pulled a lifter that was seized up put so they probally all are bad how do i know if there is any other damage?

[@martinbuilt]

I would replace all or at least on that one side the fact that you were able to pull the rockers out out by hand indicate they were collapsed lifters you're lucky that the rockers stayed in place. When you say that the lifters were seized or they will seem like a solid lifters, like you are unable to compress them in either way those are actually good. Also make sure that the valve springs are all in good shape none are broken.

I did remove the cam timing wheel from one of the older cam gears but, that is as far as I got.

[@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.

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.

[@grahammay4727]

I know this is at least 3 years ago. The links (20.05.23) are all out of stock for the new type of rockers as well. I was just wondering if you have used the rocker locks that are made for the 3.7 & 4.7L as well and if you think they would be of value and last the distance?

[@KingJamesV-jo7nv]

Thanks for your video. After doing the rocker arms and lifters on the passenger side, my check engine light came back on and I can’t get engine to rev above 2200 rpm. Could it be related to hand turning the crankshaft ?

[@pjbj3370]

Wouldn't it be much safer all the way around to just remove the cam gear with the engine at tdc, and then remove the cam bearing caps pull the cam and simply pick up the rockers and place the new ones, then reverse the process. My experience with these aluminum heads it doesn't take much at all to crack them. Prying any part of the heads edges is scary. Would rather spend a little more time doing the job right then chance a cracked head🧐 I attempted this pop out just to see, and sure enough, I ended up with a crack... Not from actually removing the rocker, that was after I found a broken valve spring and a dropped valve seat. I mic dropped the ratchet which conveniently landed right on the edge of the first air intake flange and cracked the corner.

Hey Martin! Love all your 4.7 videos! You have no idea how much I have learned from your videos!! Thank you. Wondering what rocker arm brand you put in with the new design? Huge price difference and origin of manufacture. My rockers seem all right, but have old style you mention in video (2001 dodge dakota 4.7). Swapping all lifters and seems like good time to change to new style. Received DNJ (made in china). Got the similar priced EngineTech rockers you mentioned above coming this week. I am torn if I should just leave the old ones or not. Just don't want to put in low quality arms, but think the new design makes sense. Also everything says the Melling MR-1345 rocker doesn't fit 2001 but fits 2002, do you think that is a screw up or is there something to it.

[@martinbuilt]

Thank you, I really appreciate that. I like the OEM rockers and I just get them from the local Pick-a-Part and them just clean them up with some Totally Awesome and reoil before installing them. The Melling MR-1345 will fit all 99-13 3.7 and 4.7 engines.

I just rotate the motor and cam so the lobes are in a neutral position and take the bolts out of the cam caps and carefully lift the cam without affecting the timing to remove and install the rockers. Way easier that way

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.

[@bigbo7632]

Martin quick question. I had my motor at TDC and I was installing new chains amd sprockets. When I pushed up on driverside camshaft vise grips slipped and the timing mark moved to about the ten o clock position. Can I rotate it back to proper position? Thanks

[@martinbuilt]

It's not unusual for the camshaft to rotate after you remove the timing chain as long as you marked the sprocket and the chain and return them to the exact same location and then you'll have to rotate the Cam to get the gear back on you should have no problems.

[@daddybiggs9343]

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.

[@martinbuilt]

also, check the wiring at the fuel injectors. How is it running? does it have a rough idle, poor MPGs, or loss of power?

[@dawnofthedew7303]

Hey Martin… I just did a head gasket job on my 4.7.. I soaked my brand new lifters in oil prior to putting them in the head and when I pulled them out the oil they had a good amount of play to them.. prior to soaking them they did not. Is this bad? I know they were good new injectors and I don’t get why they are so movable now.

[@martinbuilt]

Yeah that does sound weird but you should be all good.

[@OscarHernandez-ym4hx]

Question. The rocker that you installed does not look like the 1st optoon of Rockers you suggested from Amazon. Please help.

[@martinbuilt]

yes the ones that I used in the video are original Mopar rocker arms the ones on Amazon are very similar with the hole on the top of the rocker arm is larger but not nearly as large as the original first gen rocker arm.

[@croquest8749]

Awesome job . Lucky me l have a 5.4 3v ford and 4.7 dodge . Both have very close in design roller followers and hydro lifters. Same issues as far as hole on roller followers early 04 05 . Original design hole is way to large.

[@martinbuilt]

Yes the lash adjusters are extremely similar I've even used ones from a 4.6 Ford in a 4.7 Dodge

[@brianparker8720]

It’s incredibly disappointing that no one shows how to remove wiring, plugs and clips. Not everyone has a bunch of spare parts from other projects. Show the hard parts. The prep details.

[@hagentidwell2284]

Use common sense

[@virgilastacy5281]

Poor set up I've got a 05 3.7 and running excellent stopped for gas and Wala instantly running like crap that's bs but I'll deal with it

[@martinbuilt]

I hear where that happens a lot where people stop for just a few minutes and then when refiring the engine the problem occurs in your case it almost sounds like a valve seat drop but I certainly hope not.

[@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.

[@elizabethloudon6097]

Do you think I can do this without taking the engine out? I don't have the tools. 2011 jeep liberty misfire on cylinder 2

[@martinbuilt]

Yes, you can. It's just easier to show in the video with an engine on the stand. Thank you for watching.

[@joeyelliott-bh3yb]

love watching your videos keep up good work buddy. i have a ram 1500 4.7 very helpful vids

[@martinbuilt]

Thank you I appreciate that. I'm glad you like them and find them helpful.

[@jamiegermaine5395]

2012 1500 4.7 dodge ram cannot get valve covers off between motor and firewall please HELP

[@martinbuilt]

Hello Jamie, how can I help?

[@juanmespinoza65]

Thank you so much I’m gonna use this upgrade on my 2001 dodge Dakota 4.7. It has a slight lifter sound and gasket leak on the driver side although it is a crate jasper engine about two years old.

[@ariele4278]

Hello, thanks for the video, very informative, Can you apply this method on 3.6 pentestar

[@martinbuilt]

Thank you. I appreciate that I'm glad you like it. Unfortunately, the 3.6 is not as easy as the 4.7 or the 3.7.

[@justinholland7657]

With the rocker removal tool (plastic clip remover) did you modify it in some way ? I can't find any that look like the one you're using

[@martinbuilt]

I'm pretty sure I got those at Harbor Freight.

[@nealecole8768]

Mine has both designs inside the valve cover 😭🤦🤦... What do you think about this..???

[@martinbuilt]

sounds like someone else has done some work to the engine in the past.

[@bbelrixx]

Martin I have a question. Have you had any issues since installing the new style Rockers?

[@martinbuilt]

No I've had no issues at all and you shouldn't have any.

[@markfleck5320]

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

[@marka2786]

no one could have explained it better I don't know where you got your teaching credentials but you are better than all , by the way , is the procedure the same 2001 Dodge Ram 1500 v6 3.9. thanks I am pleased to have found your video

[@martinbuilt]

Thank you I really appreciate that. I'm glad you liked it and found it helpful. The 3.9 l is typical non overhead cam engine installation for the rocker arms I have a video here that I did on the 4.0 Jeep engine where I upgraded the rocker arms. the installation for your 3.9 would be very similar to that. Thank you for watching. kzbin.info/www/bejne/ooOogJyLrsx3r5Y

[@marka2786]

@@martinbuilt I watched that video it was a great help but I am having a hard time to remove the valve lifters, I bought a lifter removal tool from autozone but it does not fit, is there a special tool for this, thanks in advance

[@SeanDIY]

Would you recommend replacing all the lifters if 1 is bad? My thoughts is you already have the valve cover off. Cheaper (time wise) to just knock them all out, no?

[@martinbuilt]

Yes I would recommend at least the one valve cover you have off to change them all out especially if you're doing this on your grand Cherokee on the passenger side valve cover very hard to get out because of air conditioning heater hoses and wiring that are all in the way.

[@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.
