Just started recently. Occasional drip in driveway, bottom of bell housing has a hanging drop, but for the most part, it's dry. The part I don't understand is when I pull it in the garage and leave it sit, (not my daily) nothing on the floor, but a drop hanging. Driveway has a slight incline. Had it completely tore down in August of 2014, everything from bed plate gasket on up been replaced. Internal gaskets, oil cooler, glow plugs, studded, all the goodies. Have maintenance done accordingly. Thoughts and opinions appreciated fellas. Only one shop here in town works on my truck, just curious if it's something I need to have checked out. I love my 6.0 regardless! ??
