Rick,
There is a scraper built in to the Canton 460 pan. On this model, if you overfill the pan it makes the loss of
oil pressure problem worse! BTW, when Canton says seven quarts, they mean
including the
oil filter. Their tech support recommends running a quart low!
I've had the pan off, checked to proper location of the pickup, no leaks in the mounting or pickup tube, proper operation of the trap doors surrounding the pickup. Still no joy.
BTW if you use a higher pressure or volume
oil pump on a 460 you have a higher risk of distributor drive gear/cam gear failure.
Good advice, your #2 rule!
Tom
