Not sure what to do. I can't leave it that way. Leaks way to much. I have other early flat-heads and they all leak, but nothing like this one. It has 50Lbs oil pressure. Do you think that could have anything to do with it.
If the rear main journal on the crank has any wear or ground on the low side of the specs 50 lbs of oil pressure will for sure push oil out . I always ask the crank grinder to leave the rear main full or on the high side of the specs.
