Default oil restrictor???

ok well here is the story i bought my greddy kit used installed in august last year without rebuilding the turbo ran fine for about 2-3 months then started burning oil. so i bought a rebuild kit and finally rebuilt it in january well when i rebuilt it i notiiced grooves in my shaft but thought it was ok. then about 3months later started burning oil again. so i figured i would rebuild it with a new shaft so i called up gpopshop and got another rebuild kit and a new shaft and well now a month after rebuilding it she is burning oil when the car is pushed hard, i have been told by a freind i might need to run an oil restrictor because im probably pushing too much oil pressure to the turbo. i now have my return to the oil pan and i though that would fix it but it didnt so. im wundering what else could it be. this is really starting to **** me off. what else can i check????? i have the breather hose hooked up with a catch can so i know its not getting oil from there also my ic pipes are fine so its not coming through there. what else can i do to fix this. im pulling the turbo off here in a couple days to replace my turbo to many studs with bolts since one is turning into the mani so i cant tighten it. so what can i look at???? also im running a -4an feed line with the banjo fitting on the turbo side. were would i install the rivet as a restrictor in my system????

Well, here's an easy first question: are you using the oil line and fittings that Greddy supplied with the kit? If not, then, yes, I would say we need to look at what size line you're using. I'm told the Greddy-supplied line is a -3AN, however, I'm using a -4AN line with my TD04-13C turbo (very similar to yours) with no problems for over 2 years, now.

Unburnt fuel is black smoke, coolant is white smoke and oil/blow-by is bluish-white smoke.
