Hi,

The PCV system on 3800NA works like this.

1. channel in the throttle body->intake->front head is for drawing filtered clean air to front head.
2. air travelt from the head to pan to rear head.
3. channel in the intake with pcv valve draws this air to plenum while plenum is underpressured.


Now, I have a turbo
Okay, I need a breather on the front valve cover, but how do I block off the first channel?

You can completely block it off, vent it to fresh air or in the turbo intake. When you block it off, make sure you run a breather or 2 on the valve covers. I prefer to pipe it to the air filter if possible. This assumes you can make the vent work correctly...

As far as the vent to the after blade goes... I forget the best way to get rid of it or make it work correctly.

I know what I have to achieve, but I need a direction how to actually block the first channel.

* fab plate between intake and TB
* clean channel and fill part of it with epoxy/silicone etc
* ???
