No oil pressure Kohler CH20 64632

Yeah, I didn't think of that. I think it could be done pretty easily on the pickup tube, but I'd have to go most of the way to the top of the pump to do so. No doubt it would work. Thanks for the info!
 
At the very least I recommend you polish the crank journals and verify there is no aluminum transfer from the components running dry. If there is metal transfer/ embedded aluminum on the steel crank journals, this engine is not long for this world.

Without oil circulation to cool the components, internal crankcase heat built up rapidly and the seal simply popped out of the machined area designed to retain it.

This may be much more than just and oil pickup coming off inside the case.
