water in the oil

Ok, what kind of rocker failure? Why did the rocker fail? I use rtv around the water passages on the intake. A thin coat. A dab on the outer corner bolts threads maybe. Can’t remember if they are wet bolts. I have to use engine hoist to remove the intake every time. I have a phenolic spacer that takes the place of the cork gaskets runs all the way front to back and it is close enough I can’t get a razor in to cut the rtv. A major PITA!
