Crankcase vapor vent/recirc system

If you look at this vacuum diagram you see what I mean. Of course all the other vacuum lines are gone.

So I get rid of the PCV and run that one line from the fill neck to one nipple on the UIM with vacuum. Plug the others.

Then from the crankcase it's set up just like the diagram with one line going to the canister and the other with the check valve on the end going to the catch can. I know I can do without the check valve but i kept it.

Here's what I'm having welded into my downpipe for crankcase evacuation--

It supposedly draws a decent vacuum as long as there is exhaust gas flowing and you weld it in at a 45deg angle to exhaust flow. I hope it works -- I will find out soon enough.

Personally, I like the idea of sending crankcase vapors down my exhaust than through the turbo and motor.
