Camahaft interchange 4.2/4.0
Posted: January 5th, 2016, 3:12 pm
First of all sorry if this has been beaten to death but I'm not sure what I should do in the situation I've gotten into.
I have a 2002 4.0 engine. Not a stroker. I needed to put a new headgasket on it and at the same time figured why not replace the cam and noisy lifters I had.
Ordered a Comp cam/lifter kit, 4.2 timing kit, and spring pin retainer kit and slammed it all together. It runs mostly good. That was all 2 years ago.
Last week I check my oil and find it a quart low. Put in some oil and suddenly I have a massive oil leak. Turns out the spring pin cam retainer wore a hole in my timing cover and oil is coming out.
Well Shit.
So what do I do from here?
The way I see it I have 3 options
1) Cover the hole with epoxy, and hope the chain and tensioner is enough to keep the cam where it belongs
2) replace the cover with a cover from a 4.2. Hopefully I can do this without removing the grille again because I just had the AC charged a few months ago.
3) tear the whole thing apart and put in a stock cam and new lifters, buy a new cam retainer plate, and 4.0 timing set, hope the head doesn't need to be skimmed again.
Gotta be honest, #3 isn't likely to be happening. I'm leaning towards epoxying ove the hole and hoping for the best, but I'll replace the cover if everyone here is in agreement that it would be a bad idea to just leave it as is.
Help?
Thanks everyone
