Here's two options that both work!

R32 is a bit ugly but works, drain from valve cover catch can back to rear turbo drain is general knowledge our biggest improvement is venting valve cover ie from oil cap back to catch can.

Under blowby conditions, this stops oil pumping from valve covers or can, as it is vented both ends - no longer wants to push the oil out, lets engine breathe.

Prior to this the R32 - standard engine and sump - would fill 3 ltr catch can in 40 second hillclimb - engine still strong, no fumes, remembering if there is 3 lts of oil in catch can 2ltrs in valve cover doesn't leave much for the engine! Thats why oil pumps blow up etc etc For FoSC regularity events as a safety measure ran a holley blue fuel pump from 3ltr catch can back to dip stick tube, this also worked great under extreme conditions

R33 - most of this setup was existing on car, eg 9ltr high octane sump, twin catch cans main drain back to sump - we added the filler cap back to rear valve cover can hose and earles one-way valve catch can back to sump - this also stopped it filling the catch can in 5 laps at Wakefield - following approximately 75 laps at Oran Park GP - breather hose from main catch can, probably half a dozen drops of oil!

    • The final part arrived today to un-clampify and simplify the intake Who would have though a 1/2" hose stainless bulkhead fitting designed for below waterline bilge pumps would be what I needed Test fit on a 3" offcut I had laying around to see if it would work, and it worked a treat All going well the intake will be on its "final version" tomorrow 
    • Good luck on the weekend mate
    • Must have been an absolute nightmare to drive when the power steer was out, the rack ratio/wheel size/caster is all set up for power assistance
    • Welcome to SAU, what are you looking at buying?
    • I checked the injectors again (1 and 2, since they’re easiest to access) to make sure they weren’t clogged. Even though the entire fuel system had been cleaned, I wanted to be certain. Everything looked clean, so I reinstalled and connected everything. When I started the car to confirm everything was okay, it immediately revved up high, so I shut it off straight away. I checked to see if I’d missed a vacuum hose or something, but everything was connected. On the second attempt, the car ran without the high idle, but I noticed a distinct “compressed air” sound coming from the engine bay. Tracing the sound, I pushed injector #6 forward slightly and the noise stopped — it turned out it wasn’t seated properly, despite the fuel rail being bolted down. While holding it in place, the car idled steadily without stalling and ran for over 5 minutes. At this point, I pulled all six injectors out just in case I hadn’t seated them correctly or dirt had gotten onto the O-rings. Unfortunately, I discovered that I had damaged 3 out of 6 injectors (the OEM 270cc ones) during installation. So yes, this was my fault. Since only the pintle caps were damaged, I’ve ordered a Fuel Injector Service Kit from NZEFI to refurbish them. In the meantime, I reinstalled my new injectors – the car now idles fine for over 15 minutes without stalling. I have not attempted to drive it so far. It’s not perfect yet, as it hesitates when the throttle is pressed, but it’s a big improvement. Unplugging the IACV with the new injectors idles at around 800rpm, even with the IACV screw tightened fully. But this is probably due to tune.
