Thanks for the input guys!!
and No. I am not 100% sure it is the head gasket. That is just my best guess, and that of my mechanic after explaining what is going on. I dont know exactly what you mean by "heater valve", because the heater system is not hooked up right now. It is bypassed. I can find no visible leaks anywhere. I have watched the overflow tank again and again at several different times during and after driving, and seen nothing. As far as the look of the oil or coolant, (I am not a mechanic), but my thinking was, if the coolant is leaking into the combustion chamber and being spit out the exaust on the exaust cycle, there would not be any oil in the coolant, correct?
As for the problem I have noticed with the hard starting in the morning (even worse if it sits a couple days), the mechanic said that may be due to the plugs being WET from the coolant. Anyway, yes you are correct, I am not positive it is the head gasket. Trust me, I hope it is not. LOL!
The only thing that makes me question the head gasket theroy at all is...after I pull in the garage and park it after driving, and I get out of the car, I can smell coolant near the engine compartment!! Don't see any wetness anywhere, but just smell it. and I am not sure, but I think if it was burning off in the engine, I would smell it near the exaust, not the engine compartment?
