sometimes fixing a problem is better than putting a bandade on it, yes more crankcase venting can only help, but why should it be necessary? i just got word back from garrett, as i suspected we are over oiling the ballbearing turbo, when i check the turbo drain output it was 42 oz of oil per minute, i thought this was too much and garrett confirmed this, they said that 18 oz of oil per minute was plenty, so i did some more testing, if you remove the oil feed line going into the turbo it can be tapped with a 5mmx 0.80mm tap to accept a standard mikuni pilot jet. (start the tap and give it 8 full rounds to make sure the jett sits below the sealing surfaces) i tested a 110 mikuni pilot jet (approx .030" orrifice size) and found that would flow 22 oz of oil per minute. this is still more than enough, but until i do more testing, it is what you should run. i suspect garrett may have recently changed the oil restictor size in the turbo because we didn't see any problems with last years testing, but, this update can be done on last years, or this years turbo kits because this new restrictor will be the primary restrictor in the oiling system.

Talked with Jeff yesterday afternoon. He has a simple fix - - - Install a small orifice in the oil line to the Turbo to reduce the amount of oil to the Turbo. He's done testing and suggested that if anyone has questions please give him a call.
