1999 Oldsmobile Silhouette ProblemsIntake Manifold Gaskets 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.
The rear light socket plate may fail causing a brake light or other rear light to stop working.
1999 Oldsmobile Silhouette Questionshow so I change the check engine bulb? (1 answer)
New GM engine with 2k miles runs perfect after warmup. I'm a little worried that whatever is wrong may finally end up with engine not starting as part wears out. This condition causes no codes to be set. Thanks for any help.
