I've noticed a coolant smell from my car when driving, and thought maybe my head gasket was leaking. I tested it recently and seemed to find nothing wrong except a drip at a hose. I can't place a specific time this started since I've always been doing something to it.
Still, it seems like coolant might be leaking into one or more cylinder upon shutdown. I was running an errand today and after making a quick stop at a store I noticed what may have been steam from the exhaust at start-up, and it often has a miss that goes away after a very short while.
My question is can coolant leak into one or more cylinders when the engine warms up, and is shut down? :confuse2:
I'm thinking that I have a head gasket leak that is obvious symptom free except that coolant leaks after shutdown when the coolant system pressure is at 13psi and the cylinders are no longer under compression from running. Theoretically this could and should also leak combustion gasses into the cooling system, but I haven't noticed this, haven't seen bubbles or signs of over-pressurization of the system.
I have a head gasket and could swap it in in an afternoon, assuming everything looked good when taken apart.
