Tom, I already have a restrictor. I have a billet aluminum flange with a -4an male end on it, and it has a 1/16" hole to feed the turbo with. Even with the 1/2" return line, it's still pooling up. Now to say it isn't the turbine shaft seal, I can't until I tear down the turbo. But, I'll replace the drain line with the honker -10AN, and go from there.

My camera's battery died after taking a couple of pics, and it's charging now. But I pulled the turbo again and found it is not leaking in the compressor housing at all. The turbine and the down pipe is chuck full of oil though.

I'll be pulling the DP to clean it out and swabbing out the cat-back with a home made giant Q-tip (broom stick with rags tied on the end), while it's off

Just killing time for the compression tester and misc items to get here...
