2013 Freightliner Cascadia leaking oil out of exhaust

Engine might be worn off already, can take head off to check it out

 

Yes, you would need an overhaul, very expensive. You can drive like that for a long time though, but only if you have def deleted.
If your engine is worn off, you gonna notice oil consumption.
Still, it might be just the turbo. Take the truck to a mechanic and let him check it out asap.
I would stop driving until I made sure that turbo is ok

 

Are you sure it's oil and not slobber?

 

What engine does the truck have?

 

That’s the air side. How do you get oil in the CAC without the turbo being bad? Prolly coming out the hot side as well.
