no prime in oilpump problem fixed! - 05/09/24 10:34 AM
Last fall I had issues with the oil system priming after sitting any length of time. I pulled the NEW Milodon high volume pump apart, and found it to have .004 end clearance. I hand sanded the housing down till I have .0017 end clearance, and now the pump pulls a prime right away. Milodons spec for max end clearance is .004. Why they would send them out the door already at max end clearance is beyond me. But I am now somewhat happy. Next problem, I have a big leak at the rear main seal. I put phosphorescent dye in the oil to help locate the leak, and after running the oil pump with an electric drill for over a minute, the only leakage is coming out of the seal area, so a new hi performance Felpro tan colored seal is on order.
