72 318 Scamp. Low oil pressure 1 minute after startup.

OK, thanks for the compression readings. The reason to ask is to see if the bores/rings seemed to be in decent shape, then I'd be more inclined to go with it. But sounds like you are going down the 'exploratory surgery' road anyway; good deal.

And thanks for the update on #8 rocker oiling. Who knows how that got there.....
