First let me apologize if this has been asked before. I tried the search but can't seem to find anything exactly like this. My stang won't start. It has coolant on all of the spark plugs. No or very little compression on 5 of the 6 cylinders. The radiator is cracked and when the car cranks, it spews coolant from the crack in the radiator. I'm thinking head gasket, but whats the chance of the gaskets on both sides failing at once and would there be enough compression in the cooling system after a h/g failure to crack the radiator? I'd like to hear your thoughts on this before I tear it down. Thanks
