It's not loosing a whole lot but it is. There is no water in the oil. Replies to this message: kiawah (Feb 08, 2008 2:35 pm)

Into the intake manifold would then be spit out the exhaust and typically you notice it with white smoke (moisture) after the car has warmed up. The real concern is that you can ruin your cat converter, which is a costly problem.
