Dodge Durango Increased Oil Consumption Due to Intake Manifold Gasket Leak

(6 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.

Plenum intake gasket leaking. Was consuming a quart of oil every 500 miles. I added a liquid gasket sealer to the oil and now am only using a quart every 2000 miles. But it's only a matter of time before it will require a replacement gasket costing approximately $1200, mostly labor. Research shows this is a common problem due to an aluminum plenum contracting and expanding at a different rate than the engine block due to dissimilar metals. Bad design. -
Increased oil consumption and haven't tried to fix -

2 1/2 quarts of oil had to added within 2 weeks. Truck developed misfire on cylinde #8. Took it to firestone and sparkplug was fouled by oil leaking into cylinder. Check engine light came on. I'm guessing this is the intake manifold gasket -
