I am so absolutely careful about changing oil and levels and I put in Amsoil and It was perfectly clean and oil that came out was dirty and definately looked like primary oil mixed with engine oil.
Glider,
Do you think seal blew out because of pressure on crankcase due to oil getting past that check valve you told me about the other day? Also, I put new cylinders and pistons less than 10,000 miles ago and I noticed that rear base gasket is leaking and it wasn't before I put it away for the winter. Pressure in crankcase cause this too?
One more thing, How much of engine do I have to take apart to replace this seal? I had inner and outer primary all apart last year when I rebuilt transmission. I don't want to deal with this now. Maybe try some STP stop leak??? Just kidding.
