can oil vapor break a turbo ?

[farmer]

well as you know i had some issues before about a no boost situation, i found the problem to be a broken turbo shaft in the rear turbo. I have replaced the rear turbo and the car runs fine now untill...... I went today and had a cat installed on the car , the guy at the shop told me to take it out on the highway to heat up the cat. so i take it out on the highway and go for a rip. after about ten mins on the highway i decided to se how fast it could go, so i let it go and at about 240ish i loose all boost , so i slow down and pull over , i checked the piping to se if anything fell off and it was ok , i tried to drive it and i had no boost again (same as before) so i tow the car back to the shop and pull the intakes off and start the car , the front turbo spinns ok but the rear wont spin.

So i take a look at the pieces i took off the rear turbo and notice theres alot of oil comming from the intake of the turbo. above normal i think.

So my question is , can too much oil vapor cause a turbo to break? if so wold an oil catch can help me ? i dont want to be replacing turbos every month or so

thanks

I don't know about oil vapors hurting a turbo much. My thought would be that your other turbo has blown and is now leaking the oil past its seals.

I Hope I'm wrong.

I think blow by might be owning your turbos with a ton of oil and sludge, I'd go catch can but of coarse there are other things to check first.
