Question about 2002 Pontiac Aztek
That is not a good sign. These are a few ways this can happen. Bad head gasket, bad intake manifold gasket, cracked or warped head, or a cracked engine block. If the intake manifold gasket hasn't been replaced yet, have it checked for leaks. The 3100 and 3400 V6 engines are prone for intake gasket failure.
