your probably also getting water into the oil system. When the engine
is shut off, the oiling system immediately loses pressure - the cooling
system retains pressure for a while - if there's a hole between the two,
the cooling system is peeing into the oil during this time.

It's an excellent way to destroy your main bearings - turning a simple
head gasket replacement into a complex engine replacement.

Of course, I'm sure your 'certain' there's no coolant in the crankcase.
Famous last words. By the time Joe Shadetree Mekanik can see water
in the oil, the mains are shot.

and you are getting cooling fluids into your oil tank ... they are mixing
and must not. good think you found it. usually tis a head gaskey that has
blown to make this happen.

When I've had coolant in the oil, it shows up first as a milky foam looking
substance on the oil cap. If you've got something that vaguely resembles
dirty mayo on the inside of your oil cap, or along with your oil when you
drain it, you're in trouble.
