The intake manifold gasket may develop and external engine oil or coolant leak. In some cases, an internal coolant leak may occur causing coolant to mix with the engine oil. Our technicians tell us that operating the engine with a coolant/oil mix can result in internal engine damage. Replacing the intake manifold gasket should correct these leaks.

I took my car in because I heard a squeaking sound and thought it was a belt. it was the water pump anyway they told me about the manifold leak and it would cost $1000. I was very sick to my stomach because we had this problem fixed 2 or 3 years ago.

Nothing seems different about the way the Alero runs, but when I took it to the dealer for unrelated repairs, they discovered that the intake manafold gasket was leaking oil. They said that it would not necessarily create a puddle, but rather would stream along the bottom of the car as it is driven. So far the coolant has not mixed. Watch out for wheel issues (control arm, brakes) with this model.
