    On the leak down test, make sure the piston is at tdc before pressurizing the cyl. If you still have a cyl that has a higher leakage %, hunt down the leak path. Listen for air passing through. Leaking air sound in intake=intake valve. Sound in exhaust=exhaust valve. Sound in oil fill stand= rings/cyl wall clearance. Sound &/or bubbles through radiator fill= head gasket.

    But based on the findings posted thus far, can I rule out that I'm losing oil to combustion ? Or is that still a possibility ?

    Based on what you've said, I'd think oil is going somewhere else. However, not 100%. I won't say it isn't oil being burnt (you do have some fouling), but at the level of loss you mentioned, you should have smoke.
    Check pressure leakage again.
    Make sure oil is full. Check for leaks (pull skid pan off). If you have any oil on the motor, clean the motor, then drive it to get it up to operating temp. Once up to temp, give it a few good accelerations (in a safe and LEGAL manner) and check for smoke. Park the truck with a piece of cardboard under it (make sure it is under the truck from bumper to bell housing, wheel to wheel). That will help find leaks.

    Aaaaaaaaaaaaand, he's back........... Anyway, I don't see how you could loose that much oil through a leak and not see it. And 3.5qts over 1500 miles and you'd have been out of oil real soon if you hadn't caught it. Now that you know, is this consumption steady? I would assume you're topping it off to the tune of about a 1/2qt a week. In for another epic thread.
