I recently had a remanufactured engine put into my 95 grand am (2.3l) and within weekss after installing the engine it was blowing out white smoke and I failed an emissions test. I couldnt figure out how an engine that is supposed to be like new would fail. I read the codes and a few sensors were bad and I replaced them, but the mechanic told me the car was overheating. I checked the oil and I found some coolant in the engine and he suggested I change the thermostat because it might me faulty. I had the thermostat changed and havent driven the car since so I dont know if everything worked out. He told me I might have a cracked head gasket and I am wondering if this could be true because I only drove the car about 50 miles since I had the engine put in and I dont want to cough up $600 unless this could have happened. Is this likely with only 50 milkes on the engine?
