Replying to: bena8837 (Feb 08, 2008 7:22 am) Well if it is leaving, it is either leaking on the ground, or into the passenger compartment (as in a heater core leak), or into the engine oil, or into the intake manifold. 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.
