Iv done head gaskets intake gaskets 2 new water pumps the gaskets blown 5x it's the weirdest thing when I'm idling it's fine but when I drive I have to ease on the gas or it will blow everytime I can ease into it then get to highway speeds and it will blow again I'm stumped no coolant in oil no oil in coolant I was thinking maybe radiator is plugged but I wouldn't feel that at the gas pedal and I can blow through it and see it come out the hose Iv never been stumped like this before I was thinking cracked block as well but no coolant in oil and I don't know any way possible for there to be a crack in the block lettin combustion gas in if there's no oil or coolant mixed except a head gasket and I just did that this weekend
