Report: Intake Manifold Gaskets May Leak Coolant or Engine Oil
GMC Savana 2500 Problem
Engine Affected: Gasoline
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. Running the engine with a coolant/oil mix may result in engine damage. Replacing the intake manifold gasket should correct this issue.
