i recently got a t3/t4 .60 trim. turbo is dry no oil in it. it has a small amount of side to side no contact to the housing. it does have a small amount of in and out play. ofcourse the seller says that it was fine on his car no smoking or nething. the housing has no marks so i dont beleive nething has been touching. compressor housing is dry and turbine side has regular exhaust soot. so i wouldnt think the oil rings are bad. but im worried about the in and out. my buddy seems to think its fine. he says hes running a similiar turbo on his murker with same play and no issues. ive searched and im getting mixed reviews. thanks for the help

 

What kind of turbo is it? How much play?

 

Airesearch t3/t4 .60 trim mayb a 1/16-1/8 of an inch I'm not sure exactly. I didn't know with it being dry if it would have a little play

 

It might be a idea to mark everything off with a pen and take it apart. If there is a issue, it will be to do with the thrust bearing.

I know if the oil pressure to the turbo isn't adequate it can cause the thrust bearing to wear down when the turbo comes onto boost hard.

 

Ok thanks. I haven't used it yet. I'm in the process of building right now. He had been using it and I see no sign of wear on the housing, Fins look fine. Compressor housing is dry. My buddy was saying that was a good thing. That too much shaft play would take out the oil ring. It would have oil in the compressor housing. He said since it wasnt a ball bearing with no oil in the center housing u would have some play. That the oil takes up some of the space and I guess kinda tightens it up.
