Ok, very stupid question

Maybe I should have double checked the turbo seeing it came from a guy named "Drunken Will"

Shiz! Hope that's the end of that problem!

I've found that most T3's don't have the seal between the compressor housing and the backing plate. Many just spray a thin layer of copper RTV on to make a seal or the like.

On turbomustangs.com, I've been reading up on very simular situations where they're smoking. Most people run atleast a 5/8"/-10AN oil return line to stop issues like mine. They also atleast run a -3AN or -4AN feed line with a restrictor, which I do have.

How large of an I.D. return line do you all run? Mine is 1/2" copper with high temp hose ends simply to adapt it to my fittings with hose barbs.

On top of getting the missing gaskets, I'm considering ditching the hose fittings and get down to the pipe thread to -AN adapters, bore them out to as big of an I.D. as I can, and build a new solid return line that's 5/8" or 3/4".

Where does your return line enter the engine ... pan or block? Also, what fixture is at the return end ... slip fit or threaded? If you feel like doing it right, I would suggest these guys as a starting point to design you own solution: ATP Turbo: Oil Supply Section

Here you can customize the return line (10AN) however you want it: ATP Turbo Return Oil Line Customizer

Slip fit with -AN to NPT adapters on both ends, and it's tapped into the block above the pan. From everything I've read, I am damn sure this is my problem. T3's do not have oil seals, but rather piston ring type rings. I'm not dorwning my turbo in oil because of the feed, but because it simply can't drain fast enough.

Thanks for the link, I'm going to order a return line from them today

You can get those lines made up at any hydraulic hose shop around town. Shoot, most high performance auto parts shops will have the braided stainless and push lock or screw on type ends that you'll need too. Should be quicker and probably the same or less cost.

What size is the restrictor? You only need about a one thou hole in it. There are several ADC turbo kits out there with a half inch drain.

Edit: none are running your turbo however.
