I was curious what you guys have found to be a good catch can and crankcase ventilation setups for boosted VQ's.

I read over the 20+ pages of IMO bullshit on the 350Z forums seemed like no one had a definitive setup.

After reading I was thinking of drilling out my PCV valve and adding a 300ZX brake booster check valve between the mani and the catch can. And since I am replacing the Drivers side valve cover drilling the baffling out of the rear intake vent tube hole.

Any Ideas?

 

Why not just run it from the passenger side valve cover (PCV) to lower intake manifold?

 

There is a great thread about this in the FI section of my 350z site.

They say any check valve at all decrease effectiveness......but plz read thread as I might have misunderstood.

Drill out the passenger side PCV, throw a breather filter on it and cap the intake manifold port to the valve cover... put a breather filter on the back of the driver side valve cover too.

 

unless you have an issue why change it from whatever the kit manufacturer recommended ?

 

This then drill out the drivers side valve cover port to .5" vent both through large rubber hoses to the road...

 

Thanks for the help guys. I ended up drilling the drivers side VC aft breather hole out more. seems to be fine now.

 

I used the hole nearest the firewall. pretty sure it's a larger hole than the ones mentioned.
