Jeep Grand Cherokee Increased Oil Consumption Due to Intake Manifold Gasket Leak

(10 reports)

On 3.9L V6 and 5.9L V8 engines, the intake manifold gasket may leak and cause increased oil consumption and a spark knock during acceleration; the gasket should be replaced.

We are using about 1 qt of oil driving the car 200 miles. -
