Why do you have a check valve before the turbo? The turbo is always fed with high oil pressure on the feed side so i don't see why a check valve before turbo is needed. Since the oil is at 60 psi+ on the feed side why would it ever see back pressure?
Also why a check valve on the drain side. If the turbo is above the oil level no oil would enter back into the drain line.
I'll do it and get these parts but it has to make some sence to me
Im guessing you get the supply of oil right at the oil filter unit. I have to unplug the brass plug? Thats how mustangs are must making sure its the same for vipers.
Alright Dan thanks for your help

if you dont put a check on each side of the turbo the oil will drain into the turbo and smoke on start up. The turbo is the lowest point in your system. Yes you need to t off your sending unit for oil supply to the turbos, running 3/8 braded line. Vipers have 40-60 # of head pressure so if you dont restrict this you will blow oil right past the turbo seals and it will smoke like a fogger! Turbos do NOT need much oil 10-15 lbs of pressure is fine. If you use the surflow pumps you will not need a scavange tank.
