My son has a '74 CJ and the right bank is smoking. We are going to pull the valve cover on Tuesday and check to see if the drain back holes are clogged as well as putting new valve stem seals in and checking compression.

My question is (since he doesn't have much money after buying etc.) if we find a bad cylinder, can we just pull that piston and replace the rings?

Also, would we have to pull the intake or can we get away w/leaving it and re-sealing it up (that is if the valley pan doesn't give way).

Thanks,
Jim
