I took off my fist charge pipe that attaches to the turbo's compressor housing outlet and notice on the inside of my coupler (the housing is clocked pointing the outlet straight up) that there is some oil puddling there...just a tad bit, the inside of the pipe is oiled up but nuthing in the rest of them..there dry.
Anyways thats not good..so em i blowing oil passed the seals becuase of high oil pressure? I have a ecotec and i know therew known for high oil pressures...but when i start up the car it sits around 60 PSI at the hight at idle...then warm up its around 25 at idle..doest really move too much when i drive it...i have a 4 an oil feed with already a restrictor at the turbo oil inlet?!?! Do i need to put another restrictor at the begining of the oil feed line (off my head) to make 2 restritors total??? would that be a good idea or is it too late now and ill have to change the seals in the turbo?? ....i have no other leaks outside of the turbo.
The seals are probably just fine.
My advice is to lower the pressure until you register 5-10psi when fully warm. Some people run fully warm with no pressure.. I'm no expert on this, but according to Mr. Bell, 25psi at WOT should be observed, and 5 psi at idle. This may not be possible, but given the above info, you should be able to find a range that is high on full cold (but not high enough to cause leakage) and still register acceptable pressure when fully warm. Really it's just weighing the different pressure ranges you get with your system and deciding minimum and maximums for various operating situations. Good luck.

Ok..well ill end up putting that restrictor on the head also if i can...it cant do no harm doing so...my return is a 1/2 barbed on each end...with a -10 an braided hose onto it. i know rule of thumb is to use no less then 1/2 and be the minimum...
