I found a small pool of oil on the garage floor every morning and in both the exhaust and intake tubing.
or am i wrong?
I was going to set it up in this order:
tapped 1/8th NPT(the right size?) barb fitting above oil filter into half inch ID hose -----> turbo ----> mocal oil pump ---> check valve ---> filler cap
just in the process of getting all the oil supply/return parts i currently have oil pump on order, turbo, BOV, wastegate and charge pipe
lol i appologize this is new to me so we'll see how it works!
Thanks

The check valve does go before the turbo. The way it works, is you install it normally so oil flow though it. Check valve have about a 1 psi "cracking" pressure, which means that when you shut the motor off and you have no oil pressure, the valve is held shut, which keeps the residual oil in the feed line from running into the turbo and seeping past the seals and in to the housing which makes it smoke when you start it back up. Makes since?
As for the rest of you oil system, The STS kit uses the oil fiting you are talking about on the motor, but the line you are plan for is WAY biger then you need, STS used a -4 AN line, which is 1/4 and then the retune is 5/8 off the turbo to the pump, which is abput 2 feet and then 3/8 from the pump back to the motor. Turbos need very little oil, on the S-10 I turboed, I had to put a .063 restrictor in the feed line to limit the amount of oil flowing to the turbo, because it would push past the seals.

cool thanks for clearing things up
I tapped the oil fitting today and ran the supply line, i realized that was too big so i ended up using -4 anyways (capped it for now). Also changed the pcv valve now just waiting on the oil pump to finish the rest!
I appreciate all the help thanks
