I have a Mercury Sable 1995(3.0 V6) with over 100 000. Suddenly as I was driving, I noticed a loss of power(car revs up to 6000 rpm and does not shift), with white smoke coming out of the exhaust and the engine was heating up. I stopped the car as soon as I noticed it, and it remains parked today as we speak, I even had to tow it near my place to await a better diagnosis of the problem. Based on the symptoms, is there a possibility of the head gasket being blown? I would like to know if changing the head gasket would do the job or possibly could there be a little crack in the cylinder head? I can change the gasket head myself but I would like to know if I would be wasting my time and money? Changing valve, water pump and head gaskets could it remedy the situation? And what would explain the fact that the car, upon startup, does not shift up to 2nd gear but stays at 1st gear? Or maybe is it the computer that senses a bad combustion therefore preventing a shiftup?
