Re: Milky oil cap and down in pour pipe but dip stick looks good?
Don't mistake our suggestions as expertise. The mayo could be what we say but again it could be a leaking oil cooler which is catastrophic if ignored. If it were a blown head gasket there'd be overheating and loss of coolant. Mechanics unfamiliar with the L81 engine are quick to blame the head gasket. While it does happen it isn't very common. Just keep the coolant level right and you shouldn't have to worry. Still some kind of compression test couldn't hurt.
