VTT Cast/CNC Valve Cover OCC Setup

AUbeast86 · Feb 27, 2020

I recently installed a cast/CNC'd VC from VVT and wanted to post some pics of my OCC setup. I've been an advocate for years for running an external stock configuration for PCV but this new cover flows too well to run that now and honestly, I'm really liking this config now anyway. It's much simpler and should satisfy all of my requirements. I'm using a Radium OCC and some of their orb swivel fittings, which are really nice. The Radium OCC is non-directional for flow so I'm trying to use gravity a bit to help with the separation. I'll evaluate after a few hundred miles on how effective this setup is at keeping oil out of the intake pipe.

I have been overwhelmed at the product page for this valve cover and routing for OCC, I will be honest.

Your setup looks great! You have it routed from valve cover to catch can and then the air/gases (minus the liquid) is routed into the intake for the turbo(s)?

Thanks! That's correct.

Drop us an email, we can help. We do suggest dual cans for a setup like this. If you order the VC and dual cans. This is the configuration we suggest (file attached). We will make sure you get everything you need to route it properly.

Both can be found here. I went ahead and took a screenshot of how to configure your catch can, and attached it.

Thank you, very helpful. I remember seeing posts with this info and was unable to find it.

I see that the 'cowl must be modified', does this include the M3 cowl?

If you choose banjos you do not have to modify as they sit very low. The M3 cowl also should not have to be modified! Thanks!

Would you mind posting some more shots of your engine bay? Love how clean the harness is on top of the VC.

Not at all. I'll grab some tonight after I get the strut brace back on

Nice engine bay. Are you using one way check valves for your occ set up?

No check valves are required for this setup. This is basically a VTA system except I'm tying the OCC to the turbo intake so my car doesn't smell like a mosquito truck

Easily the cleanest N54 engine bay out there. Damn nice work man!

Thanks man! I recently did the 6MT swap and converted all the coolant stuff over as well so that really helped with tidying things up a bit. Not to mention the car runs about 20F cooler now without the the torque converter

This is awesome to see, as I'm installing same VC, but with the Dual OCC setup from VTT. I really like that Radium setup you have.

The only thing missing and maybe this is something Chris@VargasTurboTech can get going, is a fix for the unsightly stock fuel rail and connections to the injectors.

wow! Is that an original Fab Factory?!

huh. I like the fuel rails, but the injector wiring and plugs are indeed a nightmare.

It’s not only a FF but a custom 1 off Shawn and I designed just for my port meth system. #unicorn

I just think its a improvement that hasn't been addressed and would help show off the VC and provide a cleaner look for the engine bay. Hell maybe a small strip of carbon to cover it up would do the trick at least for the fuel rail itself, alternative is using the N55 mount for PR injectors. I must admit the wiring on these (R8??) coils looks extremely clean.

@AUbeast86
I just noticed the billet housing plate where the thermostat normally is, that's unique compared to the normal block off plate. Is it just a redirect to mount the oil cooler lines on the bottom of the housing?

Thanks. I’ve had this car since February of 2011 so I’ve had a little time to get shit half way right lol but it’s been a hella expensive learning experience

It’s a Mossleman TSTAT that replaces the stock one. 185F cracking temp keeps the oil right in the sweet spot to burn off contaminates and never goes above 230F when I get stupid. I’m also running a Setrab 16 row cooler core though. The TSTAT is a bit pricey but totally worth it. It’s high quality.

oh.. oh myyyyy.

You have an incredible custom driveshaft from DSS (which I WANT!). Freaking awesome build.

... you showoff

Did you modify your coilpack harness ?
