Another job dropped on my door step. Local gent was having issues with his Dakota with a misfire code P0304. It's the little V6 engine. So I told him to order the gasket for me and drop it off and I'll get it changed out. You'll notice the oil in the inside of the manifold which is typically when the plenum gasket fails. It will start drawing air from the cam valley drawing in little bits of oil. The owner also admits the truck had a K&N filter. You'll see the amount of grit and dirt
