hey guys new to the forum i dont own a jeep but my little brother does. recently i discovered it tossed exhaust rockers on #1 and #3. ive found a couple posts about these 3.7 tossing salad, i mean rockers. i need to know best place to get new valve springs if the old ones are damaged. i dont think they are but hey im not a jeep guy. also i saw where one guy put washers under his lifters to prevent them from collapsing as far causing slack in the rocker arm.

i need to know the best way to fix this. seems like nobodys found a sure fix yet. thanks in advance for your help guys i need to get my bro back on the road

so nobody has anything for me on this? come on guys help me out here. my bro needs his jeep back for school and work. from my research if i just put them back in theyll just pop out again. id rather fix it right the first time and be done with it.

I ran across this youtube video explaining how to fix the rocker arms on a 4.7 (same as your 3.7 but with two extra cylinders). I was scouting youtube last week because my engine had a rod bearing go bad and I was listening to various engine noise clips to identify the noise I was hearing. Youtube has additional rocker arm vids as well, but most of them just show the problem, not how to fix it.

You can get the parts from oreilly auto parts. Don't put washers in the engine to try and half booty a fix. Do it right the first time.

so i got it back together last night started and ran fine (w/ washers under #1 exhaust lifter). i started it again this morening and i heard it throw a rocker. i left it until this evening when i got home to find it snapped the rocker. im not sure if the washers caused it or if it happened after it fell.

im having a difficult time finding valve springs or rockers. autozone, orielys, advanced none of them have the parts. they all have lifters and thats it maybe valves. i ordered a new rocker arm off amazon it will be here tomorrow. im gona try to remove 1 of the 2 washers. when i installed the lifter initially the cam lobe was not close enough to the rocker added 1 washer still not added 2nd washer seemed perfect. so ill try 1 washer this time. the cylinder has 150psi compression so i doubt the valve is bent or the spring is bad.

Try RockAuto for parts http://www.rockauto.com/

or for genuine Mopar parts:

I dropped a #2 exhaust a couple years ago. Saw the washer trick but I just popped mine back on and it never happened again. If they keep falling off something is definitely wrong. Lash adjusters may be toast and are available from the above.
