Do you have a crank scraper on the motor now? If not, you need one up
I build my own out of sheet metal and shoot for .020 to .045 clearances from the rotating parts, I build and install it on the passenger side, 1.0 inch holes for oil back at each main web and one at each end of the scarper for oil drainage: wrench: wrench uptwocents
