I have a stock 69 340 wasnt paying attention i was low on antifreeze she got hot and ive got antifreeze into my oil, i di a compression test and all cyl. are 130 to 150 my question is how do i find the culprit is it possible just the intake gasket blew or timing cover gasket how do i get the milk out of the engine before there damage whould it more likely be a head, just looking for a direction , also should i put oil back into the oilpan to prevent rust while im doing the heads thanks
