I just noticed that one of the top 3 bolts in the center of my valve cover is permeating oil around the edge of the bolt. It is so minimal that it is hardly noticeable. Everything else is bone-dry. I just had the valve cover gasket replaced last year, is this normal? I have a 94 SL2 with 90K miles. I have an appointment to have the gasket changed next week, but I am concerned as I drive about 60 miles a day at highway speeds (above 70mph) and am concerned about compression loss or engine damage. I am not low on oil. As long as I make sure the oil is at level, is this ok? Thanks.
