Major motor issue
So here are the details.
Sunday. Truck running rough and knocking. Stalls out about a mile from home. Get started and get back home. No oil on dipstick. Just added a couple quarts to top off about a week before.
Monday. Add 8 quarts of 15W-40 dino oil. About 1/2 way between add and full. Runs good.
Saturday. Knocking a little after leaving work (few miles away). Get home. No oil on dipstick. Add 8 quarts to bring oil above add level.
All this time, oil pressure gauge never changed when running. Always in center. I know, dummy gauge, but no oil should move it, right?
No major blue smoke that I can tell when accelerating when engine warmed up. Just a little on start up - say 15 seconds.
No oil in the fuel bowl.
Where is the oil going? No pools under truck. What would happen suddenly to burn 8 quarts in less than a week? Gasket? Injector o-rings? Turbo o-rings?
Each time it was driven and the oil ran out, it was short trips, say 15-20 miles.
