The exhaust is showing large amount of moisture out of pipe. It was not low on antifreeze. The thermostat is good. It showed 150 psi on compression on each cylinder. Removed spark plugs all 3 were clean. Removed head , gasket looked good , 2 small spots across coolant passages very slight. The head looked good, I am wondering about a crack in head ,leaking past a passage into exhaust. Also thought about a leak at the throttle body on the intake. It seems like the engine is not coming up to temp. It did not show any codes.
