My 1995 7.3 diesel left me when I needed it most.
I don't drive it very often so it sits in storage most of the time. It has about 190,000 miles on it
and had not been smoking any oil other than the fuel. It has no oil leaks. I never have to add oil between
oil changes.
So I checked the oil a few months back and saw it was over a quart low. The disappointed me because it was
the first time I saw any drop in oil level. So I drove it about 30 miles and then parked it again without checking the oil.
So I checked it again before planning a 1,400 mile move my household trip. This time no oil appeared on the dip stick.
Now I am astonished because this is a massive oil loss that I had not seen any evidence of. Had not been watching the tailpipe for smoke. But here is the punch line: I added over 2 gallons of oil to reach full mark. I look under the truck for an oil lake and don't see anything. I start to look carefully at the exhaust pipe and I do see blue smoke at idle and a fair amount puffing once I press the throttle. I do not see white smoke like I see other posts describing.
So here it is in one sentence : all of a sudden its using over 2 gallons of oil in a distance of 30-40 miles and its certainly be burned.
I am looking for tips on how to determine the source. I see it could be a turbo seal issue or possibly fuel injector seals.
Totally stock setup, no recent maintenance to the fuel or air systems. I did need extensive brake system maintenance though, new master cylinder, new booster chamber and new engine driven vacuum pump.
Again. nothing found dripped into concrete garage floor.
