So when for a dust last night and when i got back in i noticed some oil on the windscreen. when i dopped the hood there was a layer of oil over the engine. it looks like a bit mor ethen normal and i think it might be the rocker cover gasket. I did notice also that where the gasket is sort of visable there is what seems like petroleum jelly or white grease, any idea what/why its there?

The engine is running at about 300hp and i was wondering if there was any recommendation about a replacement gasket?
