I definetly have to get something to fix this. Literally my engine comparntment has oil spray everywhere where it's all comming from I have no idea.
Sharif please don't forget to tell us how to set this up.
If you can design and put together an electric or engine driven crancase vac pump setup to keep the crancase in permanent vacuum I would certainly buy one. I can't blow silicone couplings at the track anymore and push the car off the track. It's quite embarrassing.

I was thinking...
Why not drill and vent the crankcase upper oil pan up high and run a line to a catch can and vent it to the atmosphere. Problem solved!
People drill the upper oil pan for the Turbonetics oil return why not for this.

Jet, I wish i could say this is something really complicated or remarkable, but it's not. And it's really stupid easy to do. we rigged this up in a hurry, but you can get the point.
The PCV Valve is removed and drilled out, and then reinstalled. If we had the time, we could have ordered a new fitting, and deleted the PCV all together. Now on the driver side, you need to remove the valve cover, and drill out the breather port. It's a very small hole back there....open it up. Then run two hoses to a catch can, or T-them like we did, since all i had laying around was a Greddy square catch. I put a breather on one port, and that was it.
Give it a try at your next track day.

I think my setup is similar except i have a hose coming out of the catch can and a breather on the end of it. With Sharifs style I was pushing oil fumes out of vented hood then my clothes would smell like oil.

so you dont use any check valves? just connect both sides into a catch can? how does that keep boost out of the CC?

Sharif's setup doesn't keep boost out of the crank case. Nothing will keep blowby out of the crankcase. The point is venting the crancase to relieve the crankcase pressure.
One of the issues with the stock setup is that the hole in the drivers side breather is tiny, smaller than a drinking straw. Drilling that out and opening it up will alow more volume out of the crankcase more efficiently relieving pressure.
Under boost the pax side PCV valve is closed so there is no venting throug hthe PCV into the plenum. The two valve covers are joined by a crossover hose of small diameter that vents the pax side valve cover pressure into the drivers side valve cover and out the drivers side valve cover breather into the intake.
There is no way that hole is big enough to evacuate all the crankcase pressure built up. Crankcase pressure starts to blow out through mating surfaces like where the lower oil pan joins the upper oil pan, and presurizes the oil return lines causing pressure and oil to leak out the oil seals on the turbo. It's not a good thing.
Sharif's system is simple. It does away with using the small diameter valve cover crossover as the only source of removing pax side crankcase pressure. The drilled out PCV valve is the new point of evacuation for the pax side valve cover. Thee drilled out drivers side breather hole can move more volume. The crossover is now only responsible for equalizing the pressure between the valve covers.
This does away with the recirc of the crancase vapors into the plenum.
This setup is not as good as having a good vacuum source hooked up, but this might be all we need to stop the leaks.
Has anyone thought about my suggestion of drilling the upper oil pan and venting the crancase there? Maybe there is somewhere else on the crancase to vent from?
