Working on a slight oil leak on a M20B27. The head was recently overhauled when I replaced the head gasket. Again, a slight oil leak along the front of what I believe to be the valve cover gasket. There was a recent discussion on the "Das Beast" thread about the best method to use when replacing the valve cover gasket. In that discussion, there was mention of this shaft keeper can prevent the valve cover mating correctly.
I noticed my keeper sits about .030 or so above the valve cover machined surface. Where keeper sits on top of the rocker shaft, it appears to be seated all the way down. The keeper itself, has marks on the top where someone hit it with something. I took the keeper to my sharpening stone and now the surface is smooth and it seems to be seated correctly but is sill proud of the gasket mating surface.
The gasket will take up some of that difference, but what should be "normal"?
