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.Google+

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.

I was told it could the intake valve but there's no guarantee that would fix the problem. Or I could get a new/rebuilt engine.

well I have to refill my coolant every couple months or until my sensor light comes on. Right where the transmission fluid compartment is , is where you find coolent liquid on the outside not that much , pin hole maybe. I ran my car for the past couple days alot traveling due to a death in the family and my 3rd gear acted up as in I could not get her to shift into 3rd or take her any faster than 35 m/hr. Im really hoping the transmission isnt bad. Im really strapped for cash no credit and its my only vehicle...3rd owner and ever since I got her problems had results. Only a little over 88k miles

Radiator was leaking ( well at least i thought it was) and when I took it in, I had a crusty orange fluid stuck to the side of my engine. I guess I have an external manifold gasket leak and it is leaking coolant. Said its going to cost me $2,000. I've already rebuilt the transmission on this car, new tires, new breaks, new everything. Now this.

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.
