Losing oil and exhaust break doesn’t work

[Janson]

I had my engine rebuilt late last year and ever since then I haven’t had a exhaust break. I also have been losing a good amount of oil like dipstick won’t show any. Anyone think I could be losing that much oil through my turbo?

Do you still have emissions connected?
Are you getting codes?
Over how long of a period have you lost that much oil?
Are you seeing smoke at startup, at idle, or when you step into it?
Have you checked connectors to the turbo?

Just curious, why did the Cummins need rebuilding?

Cheers, Ron

Fully deleted now. Rebuilt because it Dropped 6 Cylinder.Every once in a while I’ll get "TURBOCHARGER BOOST CONTROL "A" SLOW RESPONSE". I lose 3-5 quarts every 3,000ish miles. Lots of black smoke when I get on it , A little puff at start up,and none at idle.

Trucks fully deleted. Rebuild after drop cylinder 5&6. Burns 3-5 quart every 3,000ish miles. No smoke at idle, little puff at start up and a lot when I get one it.

Sounds like your burning it all. Perhaps the turbo is leaking into the intake system. If so, you’re probably not all that far from a runaway situation. Inspect the front of your turbo and see if there’s any play in the shaft. Also check the intake for any oil.

I have video of me spinning the turbo and trying to wiggle it but don’t know how to upload it here lol! There is very little play on it.

Is that oil in the pic? If so, you’ve found your problem.

 

[Janson]

Yes it is.

Get that turbo replaced or rebuilt ASAP sir. If the seal goes out completely you could have a runaway. Diesels love to burn oil and that would be uncontrolled. The only way to stop it is starve it of air or stop the oil ingestion once a runaway starts.

Ok thank you for your help!
