Oil feed restrictor poll
Oil feed restrictor poll Please just say whether or not you use one and what kind of smoking you had before using one and how the restrictor affected the oiling issue. I have a brand new 0 miles TC76MPS and we are having pretty bad smoking problems and we have no restrictor yet. Today we are going to start playing with restrictors before we decide the turbo needs to be sent back and serviced under warranty. DrTurbo stated he has sold over 100 TC76 turbo's and not one of them has come back to him mine would be the first. My oiling issue is so bad the oil pressure will drop while in boost!!!! I sure hope the turbo does not need to be sent in for service since I am afraid the turn around would be a whole month or more. I hope people had pretty bad oiling issues before using a restrictor and the restrictor solved their problems. We already know the drain is doing its job just fine.Thanks for replying!!!

Yeah I believe this would be the first one we have had come back for an oiling issue. We have had some comeback for crashed wheels due to debris and several for oil starvation. As for turnaround, well its hard to tell. T-netics is sometimes fast and sometimes slow....kind of a crap shoot.
STS turbo, not sure if the line that comes with the kit has a restriction. I also have the SLP hi presure oil pump. No issues, although I did blow a fuse once for the return pump so I do know what issues you can have with smoking.

I guess my main question is has anyone ever found that a restrictor did not solve their oiling issue? If thats the case I need to send in my turbo? Thanks guys and please keep it coming.

Verdad Gallardo Someone please answer the question have you ever come into a situation where the oil feed restrictor has not solved your oiling issue? Then you know you have bad seals in your turbo???? Speak to me people!
thanks man for the reply! All the info and different situations help our diagnosis of the problem and affects whether or not we send in the turbo to FI for another long hold up on my Snake Slayer Build.

there is some good info there.

Thanks Ger I have been reading that post and I don't think anyone ever comments on how they tried the restrictor and it did not help them and then they decided their turbo was in need of a rebuild.
have you even tried to run one? Running a restrictor is VERY common in the turbo world.
It is very easy to try and the results are immediate....if you have cleaned out your oil soaked DP...that is.
Be worth the 5 minutes to try it out right? Better than sending a turbo off and all that hassle. Did you contact Tnetics? They are very good at answering questions on their website.
Quite a few people state that they run a restrictor in that post and give the specifics of their combos down/oil pressure. Very informative post.

Right now I am waiting for a reply from the shop that is doing my build and they are trying out a restrictor this evening its still 8:50pm here in Cali. They were very hesitant to use a restrictor since they have never had to use one before and they have done many turbo builds. I told the owner we MUST try one before we determine the turbo needs servicing. Thats where I am right now. Sitting here in front of my computer waiting for a reply as to if the restrictor works or not. We at first thought it was a drain problem since you know the location of the tapping of the pan was not in the optimal location we since then have moved it to the top of the pan with a new larger -10AN line that has a straight downhill path. Now its either the restrictor works or we have a faulty brand new TC76MPS on our hands.

I would say the turbo may need servicing if the restrictor does not help. As long as the feed is -4 and drain is -10 with proper angle as well, then their is not much else it could be. Also if the restrictor does work it may take a little bit before the smoke goes away cause you will need to burn off the oil in the turbine side that is already coked up on the ring.
