Hi, have a 1987 trans am gta 350 tune port injection. Can I have radiator coolant in the engine due to a faulty gasket that goes between the idle air control housing wich is attached to radiator coolant lines and the throttle body. My mechanic bypassed that IAC housing and he said it stopped the coolant from entering the engine. I ask this question to confirm this fix. And before the bypass there were No signs of white smoke @ the exhaust tail pipes. Thank-you
