Blowing turbo

I have a 02 2500 4x4, strait pipe, Edge pro comp and afe air intake. A few weeks ago my turbo blew. I had it rebuilt. New seals and bearings. I put it back on and it blew again in two weeks. Had rebuilt once more and now it has blown again. Any help would be very useful as to what the real problem is.

check and see if the oil supply line is cloged might be getting starved also try getting a new turbo maby something is out of spec on the one you keep rebuilding

What do you mean by blown? Oil leak? What kind of pressures does it see? EGTs?

Other than that

Acme Diesel in Knoxville Tn. I have not seen the turbo torn apart so I can't say. The first time it blew both sides. (compresser and exhaust) Filled the intercooler full of oil. The exhaust side of the turbo and the exhaust was caked with about 1/4 inch of gummy oil, almost like tar. The guys at Acme said that they had never seen avything like that (the amount of gummy oil) Said I might have a problem in the motor causing the turbo to blow.

um ok then are you putting to much oil pressure to the turbo? something goofy with your oil pump? or is the return line cloged or pluged and causing a preasure build up honestly with out looking at it i dont know but its something to check out, or who knows maby you just have a FUBAR turbo.

Thanks. I'll check the oil pump. Didn't think of that. Poured oil down the return and it drained fine
