Gents:

Thank you for having me in your forum.

I purchased a 2000 JDM ej20tt from a Legacy GT and installed it in my 1974 VW Westfalia. Using the EMS Stinger 4424 and not the factory ems.

The twin turbo set up would not fit in the engine compartment, so I decided to use a t3/t4 hybrid that I had from a previous frankenmotor ej25. Headers look like they came out of a Baja bug, well, they did come out of a baja bug. The turbo sits right about at the alternator. This turbo appears to have come from an early 90's Nissan 300zx. Journal bearing. This turbo ran just fine and leakless on the prior ej25 turbo motor with the same EMS.

My turbo is now leaking oil at the turbine housing where the cartridge/bearing housing meets. Its a slow drip, but pesky. Drips on the pipes and smokes as well as smoke comes out of the tail pipe in blueish white and puffs of dark gray smoke on acceleration.

I have widened the oil return flange to a 5/8 with a 3/4 hose going to the oil pan in order to improve the oil drainage. I attached a clear hose to the drain just to watch what happens. It seems to drain just fine.

A: Crank case pressure? Whats it supposed to be? Am I getting blow by even though air bubbles make there way into the sump?

B: What is the stock oil pressure supposed to be hot at idle? at WOT?

C: Would it be so awful if I put the secondary vf27 on instead of the t3/t4? Do we really need the secondary turbo?

I'm not looking to race this old hippie bus, but I would like to keep up with traffic and head up hills without angry drivers piling up behind me.

I really need to get this project off and running.

Any help will be appreciated.
