I'm worried that my engine is about to blow. It's been making a fairly loud knocking sound on startup. It's a sort of metallic clattering type of knock, rather than the dull sound you usually expect from a dying bearing. As far as I can tell, it's coming from the left side of the crankcase. Maybe the main bearing, maybe the rod? The knock goes away when the motor warms up (five minutes or so).
What worries me is the bike may have been run for an extended period of time with low oil pressure, thanks to the oil pump seal that DPO forgot to reinstall at some point. It seems to have plenty of oil pressure now judging by the amount of oil leaking out of the head but the damage may have been done already.
Am I worrying about nothing or might the motor be about to go BANG in a big way? I hate to do a total engine teardown at the start of the season but that's better than having it self-destruct.
