High oil usage

[Kevin4857]

I have a 99 7.3 turbo powerstroke with only 135,000 miles on it and it has used 2 gallons of oil in less than 500 miles! No major leaks and it has been well taken care of. Any ideas?

Does it smoke very bad?

Injector o-rings

might wanna check and see if your coolant level is rising. see if its smoking. might be time for a oil report from blackstone and also a ring job.

That's a lot of oil!!! Don't drive it, if the coolant looks good, send a overnight sample to Blackstone Labs, sure sounds like Injector O rings to me.

Injector O-rings. I have 3 International DT466 Flat Bed tow trucks that I work on at my work with the same style injectors that we have in our 7.3's. All 3 of the trucks I have done injector o-rings on because of fuel in the oil and oil in the fuel. The oil on the trucks were constantly low but no leaks.... which led me to the injector o-rings, which were shot and leaking. Replaced the o-rings and all my problems went away! (for now) lol

Will the injector o- rings make it lose power and miss alot when you crank it up.

well it may casue it to run like sh*t, in my experience with the tow trucks, the drivers complain that the truck runs like a$$ and the oil level is constsntly down, or up but not where it should be.

yes sir.....they run terrible cold and usually not quite right warm either when the o rings go......usually are hard to start cold too.....
