#2 Intake Rocker Arm

[llll1l1ll]

Yeah, it broke again. Anyway, I know how to replace it and everything, its just the factor of time. Now, this will sound somewhat dumb (considering as how I did the previous replacement myself) but is there any way that I would not have to take the head off to replace this rocker arm? I called my usual shop that I always go to, and he claimed that he would be able to do it without taking the head off, although he said he'd have to look at it. Is this true?


I think I got the cylinder number right; its this one right here:

------------------------------>Front of car
6 5 4 3 2 1

#6 and MAYBE #5 are possible.

#2 is not.

Pull the head, its easier.

Is cyclinder 2, the 2nd cylinder from the front of the car? (Its hard to tell from your picture) If this is the case then you can do it with the head in the car - if its the 2nd cylinder from the firewall you'll have to remove the head.

Yeah, I'm pretty sure he labled the cylinders backwards. His "2" is really number 5, and that one is possible to replace without the head coming off.

Hmm, my Hayne's manual has it labeled with cylinder 1 being closest to the front of the car, and 6 to the back. In any case, its really not that important.

I don't think I'm going to fix this problem. I'm in college right now, and I don't have the time to take apart my car to that extent (I've done this before... on the exact same part)--nor do I have the room at college. I'll figure something out later...

How?!?!? I will fix it if I don't have to pull the head.

If you pull the radiator and A/C condensor w/aux fan it's possible with the head still on. However, I think it may just be easier to pull the head unless you have your A/C removed.

You should probably replace them all while you're at it. The rocker arms are the weakest part of the valve train on the M20.

[Rigmaster]

you're wasting your time if you just pull it apart + replace the broken rocker arm without finding out WHY it broke (again.....).

I've seen rockers break due to incorrect valve adjustment (too tight), also had one that broke because the valve seat disingegrated, effectively closing up the valve lash gap. I've seen them break due to overreving too.

Due to overrevving would be my gig, hahah. Thanks to my friend driving it.
