Blown head gasket issues
Recently I have been over heating with coolany boiling/spilling out of the neck of the coolany resivor tank. I started the car (cold) multiple times with the radiator cap off to fill the radiator as the car heats up. Each and everytime I do this, I have air bubbles coming to the surface. I checked the oil and the oil is thin, runny and looks like there is coolant mixed in, plus it smells like coolant (dead give away).
Anyways, my question is when I take my heads off to replace the gaskets, is there anything else I should replace. My car has 108k miles and the engine is all stock. I am not sure if the head(s) are cracked, so I am not sure if those are needing to be replaced. But just wanted to know if there is anything else I should replace while I have the heads off. Thanks.
