I have 2001 Excurison. It is drinking oil. I have asked every one I know. Comes down to two answers. Turbo seals or a Injector o-ring. Happened all of a sudden. It will use 2 quarts in 50 miles. No leaking no smoke. Injectors have arond 20,000 miles since new. Question is how can I figure out what injector is leaking if it is? No crap I have put over 16 quarts of oil in it to keep it on the stick. It never used oil. Maybe a quart every 5 months. Thanks for any help.
I have a Oil Drinking fool !!! 7.3 Excurison

Check your fuel filter. If it’s black, or the fuel looks black, the o rings have failed.
Next thing to check is your tail pipe for oil residue.

Welcome to PSN!
Have you washed the engine? Just in case there is some new oil leak?
Drain some fuel from the fuel bowl. Then open it up. If the filter is black ... ^^^ what @matthewd11 said.
Who did your injectors, or from where did you buy them?
What year model and how many miles / kilometers?

This is probably going to sound insane but I had this problem acouple of years ago towing through NM. The man at the mom & pop place couldn’t find anything wrong and after a week of searching he ended up checking the air filter just doing a general check and it was pretty bad. He changed the air filter and it took care of the oil problem. I thought it was going to be something major because I had to have a new oil cooler a few weeks prior. The old man said he’d been working on diesels his whole life and never heard of an air filter causing one to go through oil like that. I’ve only had my truck 2 1/2 years and know practically nothing compared to everyone else here but I thought I’d throw it out there for you. I hope it’s something that simple for you as well.
Cross-post here. Note some of the most active, experienced and helpful folks are on at least the top three diesel sites (some by same screen name, others not hard to identify) so cross-posting may not yield more info.
It seemed that the prevailing theory was sudden failure in one or more injector o-rings, though noted as a rare occurrence.
The turbo seal failure theory required 4 gallons of oil to be stored in the intake plumbing while engine operation remained normal; very unlikely.
So OP, is this a bona fide problem, or are you making it up to mess with everyone?
