Yes, this is the case! My old 2.2L car was not leaking the coolant into the oil case. It leaked out. If it were to leak internally, you would see white smoke from your exhaust... the mixture of oil and anti-freeze.

When you started the car you could see the anti-freeze slowly dripping out from the head gasket seem and evaporating on the block. The smell was apparent. I dropped approximately a 1/2 container of anti-freeze in 7-10 days!!!

The TOYO tech is correct...

Yes, but the only way this can happen is if the leak ONLY lets oil from a pressurized oil passage going up through the block to the head leak to the outside, with no leakage involving cylinder compression or coolant. This is uncommon. Leakage of oil into coolant is also uncommon.
