excessive oil consumption
I have a 1995 Superduty 450. It has 117,000 miles. It uses a lot of oil, several quarts per hour of operation. I can not find any leaks. I degreased and steam cleaned the engine, the engine is clean.
It does not seem to smoke either. No smoke at startup or idle.
I would appreciate help on tracking down the cause and cure of the problem.

Several quarts an hour that isn't leaking and isn't getting burned........I'd have to say injector o-rings. The middle o-ring on the injector could be allowing the oil to pass into the fuel system.
Pull the fuel filter and see what it looks like. If it's as black as oil it may very well be. If it's been doing this for a while you could also pull a sample from the fuel tank.

Dipped the tank and it looked more like 2 cyl for the chain saw
