I have about 135k miles on it and one lifter sounds like a monkey with a ball peen hammer inside the bock, anyways, when i get around to replacing the lifter and cam will i need to have the block machined where the bad lifter was? The rest of the moter still holds 40-45 psi of oil pressure cold, and around 20 psi when its all warmed up.

any suggestions? :smokin:

I don't think that any machining will be required.
But you won't know until you pull the lifter.

They usually just collapes, and that's about it.

sorry to be the bearer of bad news , i dont know if you know , but the head has to come off to get the damn lifters out , i know this cuz i had to do it too , and they still made noise! i was angry to say the least , course , i dident change the cam , o well. but i bet youll have a good ol time with it to begin with if you decide to change all that in the car anyways huh? good luck!
