I think my rear turbo has oil blow by????

[Gordoskin]

I removed my stock twin turbo charge pipe because I was thinking about going to a local welder so that I could have it divided. I noticed that there was some oil/grease in it. I looked and wiped in the front turbo and it was pretty clean. Then I looked and wiped in the rear turbo and there was some grease/shmag inside of the turbo outlet. To my understanding this seems bad, does this mean I have blow by? If so does that mean my turbo is f*cked?

the stock oil catch is directed into your rear turbo, could just be that. does it smoke real bad?

I havent noticed any smoke

i wouldn't be too worried about it until your burning a lot of oil and smoking bad, if its black smoke then the seal is gone or if its white with no boost then your wheel is missing. but usually the rear turbo outlet has oil deposit in it as the stock system dumps just infront of that turbo.

rb's move a lot of oil. its normal to find oil in the intercooler, bov's, turbo inlet.

Even the new 3 liter turbo diesels mercedes are using have blow by sitting in the turbo inlet. I think it would be more worrying if a stock crankcase venting system didn't have any.

Thanx guys, that is a relief. I got the charge pipe divided, now I am waiting for a clutch, so I can test it out!

not that big of an issue even if it were leaking. gtr turbo swaps are quite easy. just the money is an issue for new turbos...
