i havd to remove the entire turbo< engine and heads to remove a snapped spark plug... let me tell ya, it was no fun... so before i remover the cams, i marked them and took pics< but the lifter somehow pumped up, so with slightly longer bolts, and cross patterns, i managed to get the lifter down to where it was, but now my marks seem to be a kittle off.. im talking like 1/32 from original marks.... im concerned, but even after adjusting the cam chain tensioner, its a very slight bit off..... should i be as worried as i am or will the prime of lifter correct that???? thanks, Patrickstevensog1300@yahoo.com
