Hi all, if you've seen my other posts you know I started with inconsistent compression across all 4 cylinders. AMC kindly advised to adjust my clearances but digging a little deeper I found a leak in my cylinder 1 exhaust valves. I did a leak down test which confirmed that suspicion. So in addition to adjusting the clearances I figured I would address some other items at the same time. Since I'm going deeper I figured I may as well just do the rings while I'm at it. I also found both tensioners desperately need to be replaced. They're both cracking already at 30k miles. First random question, do I need to change the cam chain guides as well? They're both very hard, is the bigger middle one rubber or plastic? I can't tell if its just old solidified rubber or what. I think the top one is metal right? Also, are there any other items that might go overlooked which I should address while here? I'm definitely changing all the rubber bits, any dowels that aren't perfect, checking the lifters and polishing the camshafts. What about the oil pump? It's fully operational but I know there's o-rings in there, do they need to be replaced by now? Is it necessary to also change the crankcase tensioner if the other tensioners are in rough shape? Is it worth doing the bottom end since I'm already here? Any other advice? Responses are greatly appreciated!
