So I just installed my new cam. I have also put on the retainer and the oil pump drive, I havent put in the lifters yet. My question is the cam can still move forward and back a little, maybe 3/8 an inch or less, just an estmimate mind you. Is it still supposed to move even with the retainer in and the oil pump drive in?

Well, I just went and looked at it again. Im guessing once I put the timing chain and sprocket back on it wont be able to move forward and back.Is this correct?

 

Yeah, after you put the timing set on it will barely move.
