1 logical step at a time. Don't jump around, dont' buy anything until you know what the problem is.
1. Please fill out your signature as asked earlier so we know your truck details.
2. Did you go for a long drive as mentioned to see how that affected your oil level?
3. It's hard to tell in that picture but that black ring is a metal snap or spiral ring that is designed to hold the turbo air guide in place. The gap is totally normal. Going from that picture your turbo looks fine.
Did you check the turbo shaft end play?
This is from the BD Diesel website:
The specs are from the BD Special turbo but the procedure is the same.
Just going by experience...
Zero to very little end play.
Very little up & down play. The compressor wheel should not touch the housing, nor should there be any rub marks on the housing...
Oil is flowing thru the turbo shaft center section at all times. The turbo shaft rides on bearings & there are end seals to seal the shaft.
You can see a braided stainless steel line from the top of the oil filter head to the top of the center section of the turbo.
From under the turbo you will see an oil drain tube going back to the engine.
4. Did you remove the exhaust from the turbo? What were your findings there?

What part of Montana are you in? My wife and I love Montana. Friendly folks, nice country, great stock car tracks, excellent ski hills.
I'm just 3 hours north of the Montana border..
