I have a 1995 F350 crew cab with 460 and EO40D. This thing goes through lots and lots of oil and I cannot yet figure out where the oil is going. I bought it in Florida with 112,000 miles and drove it home to Kansas City without using any oil. It now has about 120,000 miles. The valve cover gaskets are not leaking. There is a little oil around the pan gasket and on the pan, but not near enough to be the major source of this consumption. There is never any size of an oil puddle under the truck. It never has that odor of oil burning on a manifold or similar. The engine does not smoke. In my experience if it smokes at first start you would suspect valve guides, but it does not smoke at startup. If it smokes when you slam the throttle open you would suspect valve stem seals, but it does not smoke then, either. If it smoke all the time you would suspect rings, but it does not. The last couple oil changes have been at/by local Valvoline shop, and the consumption might have started about the time I started having them do that, but not really sure. I would live for somebody to say they have been through this and know what's going on here. Any ideas?
