What does it mean when you have oil in your radiator? Specifically. I realize it means "not good".
I don't see the usual froth yet in the oil cap, but I didn't drive it that much either. Oil appears to be just oil, for now.
Head gasket? Water pump? It's the 1988 3VZE with 261K miles on it. Had the head gasket done once (don't know when but likely many years ago when recalled).
Thanks in advance.
