Took my turbo apart...... :(
Hi Team,
I just recently took my front turbo, off of my FD, apart. Cleaned it up and reassembled it. It leaked oil...big surprise.
So I took the exhaust side turbine and shaft back out and examined the seal. There looks to be a very, very, very thin carbon ring in the housing assembly that mates flush to the exhaust side shaft's compressable seal ring. This carbon (I think) ring is worn/damaged.
Now the question; how do I replace this carbon ring? Is it replaceable? Did I just cost myself a crapload of needless trouble?
Thx,

Alright, got good news today.
I drove down to the local Turbo shop and had the guys take a look at it. There is a groove in the shaft hole near the end of the turbine side. But, there is no seal in the groove. It is there to build up a carbon deposit and aid in sealing the metal compressable ring seal around the shaft.
They just instructed me to put it back together with the thick petroleum lube you seat valves with. This non hardening seal will act as a barrier against the oil untill the engine deposits build up and displace it.
I have to figure out a way to test it for leakes though. The housing is designed to be aligned in a certain way. In this, and only this, position, the oil level will only be about half way filled in the shaft cavity. Any more and it will leak. This is hard to do on a work bench
