Oldsmobile Silhouette 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.
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. - Visitor

At 94, 000 miles replaced transmission, 96,000 replaced motor when camshaft broke, oh also replaced head gasket at 93, 000 now at 161,000 head gasket is leaking again. Headlights alway full of water, in winter bulb would shatter in cold weather. Had to drill small hole in bottom of light to let the water drain. Driver side window needs new motor every few years. seat controll broke off , never worked well. - Visitor

Intake manifold gasket developed coolant leak Replaced gasket.
This same problem developed at 59,000 miles and was corrected exactly the same way.
This was corrected on both occasions very early upon noticing the odor of coolant.
The engine has always been serviced with Mobil 1 synthetic oil and that may have help prevent any internal damage. - mocha50

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? - Visitor
