I had a similar problem. However, my seal was never pushed out. Once, the spring was off when I removed it. Then a mysterious leak started from around the oil pump relief bolt. I changed oil pump and stock seal and so far no problems. This thread should help. http://www.supraforums.com/forum/showthread.php?t=165069

How are you venting the crankcase? Mine was leaking until I properly vented the motor, no issues since.

I am no expert, but you might want to apply some sort of vacuum to the PCV setup to get all of the pressure out of the crankcase. (like how the stock setup is) If too much pressure builds up inside you will blow seals. I have seen some nice setups where they have a hose from the exhaust side pcv to a catch can, and then from the catchcan to a vacuum source on the intake(pre- turbo).

I am no expert though. Maybe somebody else can chime in.
