Stay below 190 degrees coolant. Cut open the oil filter to look for any form of debris. If it is a Fram filter strike yourself on the head with a hammer. Friends don't let friends buy Fram filters for anything, ever.

Never lost an engine to an oil problem.

My Race engines use a flex plate for starting and a 5 1/4" flywheel and clutch cover and lightened rotors. As close to no load as you can get. Never a problem. Look at the revs first, then one half second later, at the oil pressure.
