RB turbos wastegate loose..
I stuck my hand down to the rod that controls the wastegate on my RB turbos and it is very loose...
I notice on acceleration I have extreme wastegate rattle. How do I tighten this?? Sorry for all the threads today. I'm working on the car trying to fix all my problems!

agree. Call or email Rob. If I remember correctly the outside pieces are stock, it's just the internal wastegate pieces that were modified by Rob, but he should have ideas on how to best proceed. Good luck.

There are no seals The seals are rings No way for them to become damaged since they ride in metal grooves (except of course... turbo shaft play) Remember we said no way to leak except? Well they have small gaps in them and oil can be forced through them and into the turbo housings. Don't have them, but you have them, they can't leak, but there are gaps and they can leak into the housings. |

Most are not willing or able to do the work themselves. Easier to do what that person did if you have the skills. Also, you can find great low mileage stock turbos for $300 (for both) from someone who upgraded, so sometimes that's better than the labor of rebuilding. |

So what specific part actually "goes bad" in this instance? Is it a combination of wear causng shaft play, which then allows blow by, etc.?...I ask again, what is the actual "seal" that allows the blow by to make it's way through the exhaust? Is it the piston ring? Something else?
