Started the tear down of the 235 in the 54- backtracking:
Engine started and ran but had been sitting for quite some time before the P.O. got a hold of the truck and flipped it to me. I replaced the brakes, fuel system and brakes complete. engine started and ran fine ( better than I though) but in doing my initial series of checks for the motor I found I had water in the oil ( here we go again) compression tested the motor before I pulled the head and #2 only had 30# (all others around 120#) so off came the head... The gasket was in good shape no visible breech and no visible cracks in hte head- but the exhaust valve on #2 was "sticky" so I'm taking to the machine shop to be cleaned, magna fluxed, and reassembled. we'll put a new head gasket in and hopefully take care of the water in the oil issue. in puling everything apart- I noted 5 and 6's lifters are pitted- cam appears to be ok. I would rather not replace the lifters if I didn't have to but I also don't want to run with the pitted lifters if it wall cause more damage- Can I just replace the 4 pitted lifters with new? or do I replace all of them? not interested in messing with cam if I don't have to (replace cam and all 12 lifters)
