what are the signs for replacing the oil gasket in a 1996 Chevy cavalier
Intake manifold gasket
That narrows down which head needs a gasket or which side of intake needs a gasket. Check your oil for signs of water in pan.
Engine oil mixing with coolant and/or coolant mixing with engine oil.Losing coolant but don't see any leaks. White smoke (steam) coming out the exhaust that has a sweet smell to it.
Those are signs of a blown head gasket or a cracked cylinder head.
You keep hitting parked cars and stop signs.
With a blown head gasket the engine will still run, poorly with issues, but run. A blown engine will not continue to run from that moment on.
the only way oil will get in the coolent is a bad head gasket or a crack in the head.
Ignore the signs and subtract the smaller number from the larger one.
