Here is two questions for those that have dug into the top end. 1)once I have installed the timing chian tensioner the "I" that is supposed to line up on the flywheel is a little off the mark when the two punch marks on the cams are lined up with the top of the head. It looks as though if I move the timing chain a tooth here or there it won't line up at all. Is this an exact science? what am I doing wrong? 2) the manual says 7.2 ft lbs to tighten but my wrench doesnt get that low, would it be safe to assume that it is basically snugging them up? Thanks for any help.
