I also have mayo inside my filler cap.It is not HG as I dont loose water or oil.All I want to know is how the vent lines work from the head and where does the small line go at back of engine.

its called oil and water mixed together,its just from condensation in the engine just wipe it out from time to time i take it the dip stick isnt covered in the same mayo.if so then the head gasket could be leaking.
