Banging my head! Multiple turbo failures

[Bryan_Arlaud]

@New recaros I will definitely have a look at that.

@New recaros Thanks for your input. Im going to a turbo shop next week to have the look it over and give me their insight on things. Still haven't heard any from Garrett Tech support.

Massive fail by the “venerable” Garret.

Had time today to tear down the driver side turbo for comparison. Big differences.

The shaft on the failed turbo has the black rings like its burnt and the working turbo doesn't have the discoloration. Also to be noted the working turbo shaft is much smother the the failed turbo shaft however the shaft still is not completely smooth. if you drag a finger nail on it there are still slight groves. Also to be noted the failed turbo shaft in the good journal bearing while spinning feels choppy and rough.

There is also a big difference in the thrust bearing color at the turbine. The failed turbo thrust bearing is black from heat and the working turbo thrust bearing is purple and the is some sort of a compression washer on it that is not on the failed turbo.

Strongly feeling it's a oiling starvation issue. who agrees?

Critical question - Were the turbo filters in the block replaced?

Good question!!!!!

 

[Bryan_Arlaud]

@Ellison3 Yes they've been replaced. After the first and second failures they been replaced also. The thought is a by pass of some sort is open. The turbo is getting oil just not enough. Ill have presure readings at the turbos once we get it all back together.

Good luck with that. Hope you find the answer to your problem real soon!!!

Did we just fly right over this report? You may have done this and I missed it. Cobb say the intake collapses and causes turbo failure.

Apparently that is a gen 3 issue, not gen 2
