Well finially got my cases split, and look what I found. Its a hole in case where crank shaft is. Got some play in bearing for counter balance and it must have hit side and made hole, and wore some on side to. In one of the pics you can see all the shavings in the corner. This started out as a engine that was getting too much air and didn't hold a leak down test, and I see why. So much for just replaceing gaskets and seals. I was kinda having fun on this project till this. Now what??? Do I have to replace both cases? I need some advice please! Thanks!
