So I've seen many turbo's with a seal between two parts of the compressor housing. As in where you would loosen the bolts to clock the compressor housing.

I know it's a bad picture, but this is what im talking about:


Anywho, my ebay turbo has no seal, and I was wondering if anyone else running theirs with no seal, or if they sealed it and realized it was leaking before. I was thinking of putting maybe a thin layer of RTV or finding a seal to go there, but wasn't sure if it was necessary. I just hate the idea of thinking I could be leaking air out between the housing.

 

In my turbo there are 2 O-rings there, large and larger.

 

don't worry about it. it's the compressor o-ring and it's usually a worthless paper seal, some rtv will work but I never use anything.

 

Good enough for me, if I ever have it apart again ill throw some in there but until now ill just let it be
