so i finished my set up its a true garret gt35r on a completly built and tuned b16b/9:1 comp wisco pis,12 psi... the motors fine but the turbo smokes like a oil fire it dinnit smoke untill i had about 5 hours of run time and it looks to be from the exhuast side only the rest is oil free) any ways ive checke the feed line and i have it restricted, and the return line is good as well im just gunna replace it.i researched but im not in way super knowledgable on whats my best out come for a easy cheapest/reliable replacment. would like some help from some from h-t guys please thanks!!!! oh yeah the turbo was used ehh but ran fine for quite some time....

have turbo rebuilt?

buy new one ?

 

cheaper to rebuild then buying a new one.. send it way to have rebuilt. how is the shaft play on the turbo.

 

the shaft play is about 1mm up or down ive researched and most legit h-t motor heads say there should be absolutly no play soooo i guess it gunna need some lathe work and ballancing aka full rebuild huuh? the play is very slight but it seems to be enough to smoke like a skinny tire fire... dam ehh im ima go blow some smoke to these diesel trucks that always bothered me ill be back..

 

If its a true GT35R and there is an issue w/ that cartridge, there is no repair. The compressor wheel, sure, but not the rest. you need to check which restrictor you used (should be .035" for a -3AN feed line), and what oil return you used (about a -8AN is appropriate), with no 90 degree AN fittings on the return line gravity feed to the pan. If you don't have this setup, you could have destroyed it in a way that can't be rebuilt.

Sounds like oil could have backed up in the return line. Pictures of the setup underneath with answers to the questions above will help w/ a diagnosis

 

ill get some pics up soon.thanks 4 the help. im using the obx restrictor .020'' and no i have no 90 deg on the return line and ive checked it several times it is a -8AN. im not the smartest when it comes to FI but i envy others that are knowledgable. the guy i bought off of acked scetched so it thats my fualt. but the a good possibility it was fine when i bought it so im obviously given him the bennifit of dout.it just stinks so theres no real hope for rebuild? it smokes all the time... mostly when its warm...
suggestions ?

 

.020" is a bit small.. Yikes. Suggestions..... Time for another unit. One that isn't ball-bearing, and doesn't require a restrictor. PM me for questions and/or suggestions
