Well, my turbo is STILL burning oil...

I have a .055" or so restrictor on it, 1/2" return all down hill, and it is still burning..

Gettin kind of sick of this.. its a nissan 300z t3, and was rebuilt by blaast performance a while ago..

I am using 5w40 shell rotella t syn oil in it..

I can actually see the oil in between the center section and hotside..

 

Musta not been rebuilt very well

 

i have the same turbo from a 300zx late 80s' t3 60 trim and it burns oil, not too bad though about a quart every two months. and i dog the living crap outta my car on a daily basis

 

There is a big cloud after a full throttle run.. a solid amount of smoke for about 5 seconds afterwards.. or while starting from sitting for a few..

I am gonna try moving the restrictor to the turbo side, it is on the T at the moment..

I know its not rings b/c my compression is 190/185/190/185, which is exactly at the factory spec... and the fact that oil is visible on the outside between the center section and the turbine housing lol..

It seemed to be a good rebuild, and a great price, but I dunno now

 

Im not certain, but is it possible that the valvetrain could be worn? Eg. Valve seals, Valve guides.

 

a possibility, but I doubt that just because of the oil visible on the outside of the turbo, a tell-tale sign of oil gettin past the seal

 

i would contact blaast ..your not the first to have problems with them

 

check your charge pipes, see if it throwing some oil in there, if it is, just snag another one on ebay, they are a time a dozen. also, i suggest running mobil 1 15w50 in any boosted car.

 

no oil in the charge pipes, not even a film

is it a particular seal/washer that is the culprit for the loss of oil on the turbine side? could I replace it myself if I marked the wheel location upon disassembly to not lose balance?

 

i've been having the exact same problems as you. oil restrictor, stealthmode oil lines, turbo leaking on the outside of the turbo, burning a -----ton of oil.... i rebuilt the turbo, and it was alright for like a week, then it started up again. i just assumed that the center cartraige was bad. i've tried everything else, so now i'm just gonna replace the center and wheels
