Thats a great thought, Kelly.  I'll see if I can dig up the rest of the stock oil line.

Speaking of oil pressure.  I have 70+ psi on engine start and warm up, but after the oil gets hot the oil pressure drops into the 30's as soon as I throttle back.  Is this normal?

Perhaps those 2 issues are related.
