leaking a ton of oil
My oil was leaking for about 3 weeks and then one day I go to drive my truck out of the driveway and all my oil was underneath it so I was not going anywhere.
Leaking oil at right valve cover gasket. Replace gasket to stop leak. Left valve cover not leaking, but saved the extra gasket for when it does need to be replaced.
Severe oil leak, about 1 qt. every 50 miles.
