there may be other quality options, but over the years the only reliable and quality place i have had rebuilds done for my car and others is at forcedperformance.com in florida. they were not the quickest with my greddy twins, but they did a good job and somehow even got the corrosion off the center section and it looked like fresh new castings... was around 900 for the pair, needing no replacement parts... if you need any new wheels it can go up fast

Thanks for the answers gentlemen. I just got off the phone with Robert @ Forced Performance and he said the words before I could get them out. Crankcase pressure. He thinks my oil return linesd are pressurizing causing oil to leak out of the seals, but that likely the seals are still good and that they will stop leaking oil when I get the crankcase presure issue fixed.
I guess the modifications that I made to the PCV system didn't work very well.

u never drilled out your driver side valve cover though, right?
i think tapping the crankcase (like a vortech) and running a breather up high would work well.
sounds like you will be in good hands with the rebuild. 900$ seems like 1/2 the price of new turbos. expensive.

I don't think a breather in the crankase would work only becasue there is oil present.

I think the water pump cover is closest to the crankcase, not sure if there is any way for pressure to flow into that area from the crankcase.
Just a thought, not sure if it has any merit.

It's something I don't have the answer to. I don't know the quantity of oil in the pan when the motor is running, and I don't know what happens to the oil in the pan under lateral G's. I don't know how much oil runs down the upper oil pan walls draining back from the heads/cylinders.
There doesn't seem to be any benefit of venting the crankcase at the oil pan vs. the valve covers since the pressure in the valve covers is the same as the pressure in the crankcase since the oil drain passages link the crankcase and valve covers to form a single space between which crancase pressure can flow uninhibited. So the place to vent is the valve cover.
What is amazing to me is that I am the only one with this problem. This might make me sell the car. I don't want to deal with this anymore.
