Great site guys. Too bad it took this long for me to find it. I am having some oiling issues with a twin turbo setup. I know this is a pretty common issue but I am having smoking issues across the board. The whole setup is new and there is no oil fouling on the plugs as well as no oil (puddle or residue) in the intercooler. I can actually see the oil coming out of the exhaust as a spatter with a cold exhaust. It is a twin setup with a -6 hard line off of the oil pressure tee splitting to two -4 hard lines to a 90 degree -4 to 1/8 NPT fitting at the turbos. The drains were originally -10 to the pan but I will get into that in a minute. I am running 75 psi solid cold and 15-75 psi when hot. The engine uses a dry sump oiling system with super low profile pan. I started with the drain lines run into the pan. Unfortunately clearance issues forced me to put the drain bung from one turbo very low in the pan with a 1" uphill into the pan. Figuring this was the issue the whole system was replumbed to share an all downhill run straight to one of the scavenge sections on the dry sump pump (approved by the engineers at turbonetics). I was sure this would do the trick but alas there is still blue smoke there. I know Turbonetics does not reccomend restrictors but I cant help but think there is too much flow to the turbos. They are T-70 BB turbos. Any ideas??? Thanks.

After much research online I guess it looks like It may be as simple as replumbing the system with -3 lines. Hopefully this will be enough to solve the problem. I will try it this week.

Yes that might resolve the issue. Turbonetics uses -3 AN feed lines for almost every turbo they produce.
