One of the three bolts that go from the ehxuast side of my turbo to the exhaust has backed itself out and is gone. I've been getting misfires and im running lean plus my car sounds like it has an exhaust leak and i can smell it. It sounds real cool though :p Anyway, the bolts are really threaded studs that screw into the turbo and have a nut on the other side, is it going to be possible for me to thread a new stud in and put the nut on without me taking the turbo off? I should be able to thread the new stuf through the hole and just slip a new nut on right? I'm not crazy about tearing my car apart in the snow. Luckily it is the one bolt closest to the top so I should be able to do this with just taking the airbox out. Does anyone know what size the nut is by the way?

you can get it from either vw dealer if you only need one hope they don't over charge you like crazy - or you can buy them online almost everyone carries them for about a dollar each and you will need the copper lock nuts along with it.

If the housing tread is not damage it should just go back in - but if the tread on the turbo are damaged then you will need to retread it and may require you to take the turbo out

when i replaced my turbo i bought the accessory kit from ecs including 3 of those bolts which i replaced the old ones with so i can just use one of the old ones. i need a new nut though, im not sure what you mean by locking nut, im pretty sure it was just a regular nut. i dont know what size to get, ecs says that bolt is 10x28....they have a few 10mm nuts:

the size is 10mm - "Copper Flange Locking Nut" - it suppose to prevent itself from backing out
