Buick Regal Problems

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.

Rough and/or High Idle Due to Engine Vacuum Leak

The upper intake manifold gasket and/or a PCV vacuum lines/hoses can develop vacuum leaks with age. This type of leak can result in a higher that normal or rough idle.

Fuel injectors can short-circuit
