Those of you on VEMS with no turbo inlet pipe, where are you connecting your PCV to? I realized the other day I have to run without the factory inlet pipe or drop money on a 2.75" inlet hose from 2bennet or 034.
So I'll just run the diverter open to atmosphere and maybe grab a couple of cheap 90 degree couplers to put a filter where the stock airbox goes, may even leave the airbox. So I could weld a port onto whatever I rig up for that, but I know I've seen a lot of VEMS setups with a filter right on the turbo. What are you guys doing for your pcv setup?
Thanks

We're just venting to catch cans/atmosphere.

Something similar to this is what I'm doing... Front of valve cover to a Provent vented to atmosphere.
I thought about draining back to the oil pan, but figured I rather to keep that gunk out instead of bringing it back in the system.

So you're just keeping the crank case at atmospheric pressure? I was hoping to be able to keep it under vacuum, otherwise you're just venting pressure instead of actually evacuating vapors
Re: 3B/AAN PCV with no turbo inlet pipe (on VEMS)
When running higher than stock boost, I'm sure the vapors are being pushed out with ease. Especially on a loose motor where rings are worn. I've thought about plumbing in vacuum on mine but not sure it's detrimental to vent to atmosphere.paradox11235 wrote:So you're just keeping the crank case at atmospheric pressure?

You'd pull a vacuum in an ideal situation, but it isn't hurting anything not to (as mentioned above). I wouldn't put much effort into it until you start making 600+ hp. Even then it's debatable. I don't think Gerner runs a vacuum pump...
