Ok so i found a leak at the bottom of my thermostat housing, while in the middle of a tear down to replace head gaskets.
I was getting bubbles coming through the cooling reservoir. not boiling bubbles, I got them regardless of temperature of the water. cool to the touch, or operating temperature.
I would think that a leak in the system could not because consistent bubbling, being that it is a pressurized system and the thermostat housing is at the discharge of the water pump and there would be no suction at that point in the coolant system.. but then again if there was a leak loss of pressure could allow air to be drawn in.
could the leaking thermostat housing cause the elusive bubbles or do I have a leak in my head gasket, and its drawing air from the compression in the cylinder? I want to say that it smells like exhaust in my reservoir. but no water in oil and no signs off coolant on plugs.
My gut tells me i gotta bite the bullet on this and pull the heads.
