I've noticed some gunk on the filler tube and cap when I do an oil change. Looks like water in the oil but I'm not loosing any coolant and the oil seems fine and dandy when I drain it. Could this just be condensation in the filler tube? I've read of the cracked heads and hope that's not the case, I'd think there would be some coolant loss if it's leaking into the oil - unless the oil leaks into the coolant as well????
