Long story short, I was installing a cam at my friend's garage. (He has a heated garage, I don't and the outside temp. is below zero) He leaned on the cam gear and SNAP.:8 The chain guide snapped and pieces fell down the timing chain cover. Great in vehicle engine disassembly. I hate it because I don't like all the crap that gets in to the engine despite a persons best efforts, plus I just rebuilt it 45,000 miles ago.
Upon engine reassembly I noticed that the chain has no "bright links" or marks of any kind to align with the gears. I don't remember what it was like when I assembled it during the rebuild.
What do I do? Put the marks at 6 o'clock and 12 o'clock? Count the number of links and gear teeth and divide knowing that the cam spins half as fast? Have someone look at their chain and tell me how many links apart the bright spots are apart? <img src="/forums/images/graemlins/confused.gif" alt="" />
