Thanks Jack and Cliff. Ok, I’ll do it myself. I’ll call Tom today and chat with him. Jack, I have low boost around 9-12 psi under full load absolute max boost. I blow copious amounts of black smoke. I have tons of soot coming out between the hot and cold sides of the turbo where they are sandwhiched together. This soot has now covered everything in the engine compartment and is also making its way into the living area of the coach in minute amounts. I’ve degreased and pressure washed the engine to determine if soot was coming from any of the exhaust manifolds and it is not. Only source is the union between the two sides of the turbo. I’ve replaced the vband clamp and that didn’t make any difference.
Geoff, you’re probably right. I might try that route first and see how far I get. Those two seem to be somewhat seized together but obviously there’s a gap there since it’s leaking air. I do not have a drop of oil leaking anywhere around the turbo and there isn’t any play in the shaft and the fins look fine. So it’s likely ok and I just need to do what you said but I’m not sure I could get those two halves to be perfectly smooth and seal perfectly again. I’ll give it a whirl though. Jack I know cliff had told me on Facebook which turbo I needed but I completely forgot and never wrote it down. Cliff, if you can remind me what the numbers were I’d be grateful.
