But with the seal bolted solidly to the water cooled block, it should stay
cooler than the crank. So I don't think the clearance will increase that
much.
Also, I believe 300F is pretty high for oil temp in the pan. The oil gets
significantly hotter in the bearings and on cylinder walls, and it doesn't
take much more than that to make it break down. If you're getting 300F in
the pan, you might want to think about a cooler.
