Frozen Elbow Stuck Turbo

[Captain Ralph]

I would like to hear from the turbo shop on who made the turbo.
China??
Not a name brand.

I can pretty much guarantee you that elbow has failed. Look at the pitting inside it. And the exhaust housing is chunked up with rust scale.

Find a shop or a friend that has blasting equipment to confirm, but I'd bet money that once you get that turbine housing descaled you'll have an eighth of an inch clearance between the turbine and the housing. Spec is usually maximum .040".

I've rebuilt a lot of turbochargers in my career and I've never seen one fail from sooting, or not using a "cleaner" on the intake.

That's not pitting in the elbow that is a carbon type scale. I scraped it off in a couple places and it looks solid to me. Same stuff is built up on turbo up to the fins. Im not going to mess with that part will let the turbo guy check it out.

Hope it works out for you.
