Rb20 Rocker Cover Breather Question

Alright so i've just had some custom piping made for a new turbo i've fitted and i've just realised i now have nowhere to plumb the breather pipe from the turbo side rocker cover back into the inlet piping.

I still have the hose from the plenum side breather that connects to the pcv hooked up, and i have the u shaped hose that joins the 2 breathers hooked up. I'm wondering if i can just block the outlet that feeds to the inlet piping or does this cause problems?

Any help is appreciated guys. Can also provide pictures if required.

The cam covers must be vented to something that is NOT pressurized. Therefore if you mean intake before the turbo that is OK, if you mean after the turbo (and therefore pressurized air) then it's is NOT OK.

      Duncan's V37.......race car?

      By Duncan · Posted

      Before I get to the test day, just to finish off the android head unit. This is a demo from car start up....the standard/host system takes a few seconds to boot (same as all v37) but Android comes up quickly. In this vid I'm using the delivered launcher but have set the default to Agami since which is easier to navigate when if use primarily 5 apps. You can see the host system still takes over when required eg putting it in reverse, and you can switch between Android and not by holding the back button 3 sec. It is pretty responsive (fast) but you can see I had to press harder than expected a couple of times.  I still have the phone connected to the stock system, and that also seamlessly takes over Android music playing. v37-android-demo.mp4 The bigger reason that I put this in though is so that I can use Ecutek directly on the head unit. That gives me a dash with logging (up to 20MB only), high and low value warnings on any parameter etc etc. I've run a USB cable from the Ecutek OBD dongle to a USB input on the unit, easy. v37-ecutek-demo.mp4   The unit did freeze on the launcher the other day, I think Agami was trying to verify the license when it didn't have a data connection...will monitor and report back if there are any other problems but so far I'm very happy with the upgrade.

      So 10/10 times that code is coil packs? I mean if that's the case ill drop the $400USD or so to replace them. I didn't know these cars threw codes before the issue became an issue.
