So if you DO have a breather cap and there is steam coming out (coolant level is fine and constant, no discoloration, oil color fine and slow burn of 1/2 quart after 3k miles) to the order of lets say what a mug full of boiling water would produce.
When I had a hose from the sealed valve cover tube running down under the car, it looked as if something under the car was burning and there was respectable amounts of light smoke coming out, especially after a good highway run. When I installed a breather, it changed to the gentle steam described above.
Is this normal or excessive? She's got 140K. Time for new rings?
