so i was working on getting my engine together today and came across another funny problem. i got the timing gears on and whatnot, and went to install the bolt into the end of the cam which holds those gears on, and it seemed to stop about a 1/4-1/2 inch too early, at 65#ft. with my history of breaking bolts off into really important stuff, i thought i'd stop there and ask someone if they happen to have an engine apart, if they could measure the length of their camshaft bolt. i'm wondering if the machinist mixed it up or something while it was at his shop. the other thing to add, if it makes any difference, is the book said to use some thread locker on that - so i did. can't imagine why that would stop it too early though. anyway, any comments or suggestions??
