Pontiac Montana Problem Report
Pontiac Montana Intake Manifold Gasket May Leak Coolant or Engine Oil
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.
