Well that sounds like it could happen, BUT if it wasn't getting enough oil it would smoke, not gush oil all over the place. Right?

what size return are you using? Make sure it's as vertical as possible.

It does sound like you have waaaay too much oil pressure going into the turbo. I have my oil pressure gauge hooked into a tee on the back of my block so i can see what teh psi is at the motor, and then i have another one after my homedepot style restrictor so i can see how much goes into the turbo. At the most I think you're never supposed to go over 40 psi at the turbo, or else what happened to you is usually what happens. Right now mine is regulated down so that when the motor makes 80 psi, the turbo only sees about 25 or 30.

I look at my turbo and find both sides and leaking oil again. I bought a Function 7 Oil inlet fitting with built in restrictor just so this would not happen again. What gives. What I'm I doing wrong???
There is a good chance your oil seal was damaged when you ran the turbo before you put the restrictor in. The seals can't stop any leaks if there's already a hole in them.

We recommend that you get the turbo checked out and have the seals replaced if necessary.
