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.

Illumination of the Check Engine Light can be caused by a loose or worn gas cap.
The high pressure power steering hose will commonly leak fluid and should be replaced if this is the case.

Bought with 25,000 miles on it; now has just turned 100,000. The intake manifold gasket was replaced under warranty (an inherent problem with this model).

Does not use oil.
