Report: Intake Manifold Gaskets May Leak Coolant or Engine Oil
Oldsmobile Silhouette Problem
Engine Affected: 3.4L V6
Average Mileage: 98,714 mi (56,000 mi - 130,000 mi)
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.

Had to have the intake manifold gasket replaced exactly 2 years ago at 81K miles at a cost of $1500 and now it has failed again. This part should last to at least 120K by most accounts and now I'm looking at replacing again.

I took my car in to Gregg Young Chevrolet for new tires they did an engine check and said that all the gaskets and seals needed to be replaced. We had them replaced for over $1000. 2 weeks later car died and I am now told I need a new engine. They are telling me that damage had already been done to the engine prior to my replacing the gaskets and seals. Why did they not check to be sure there wasn't damage done before charging me for gaskets and seals?
