Ok guys, before I get flamed off the page..I have spent 2 hrs :banghead: reading all the different PCV and catchcan threads I can handle and have come to a conclusion. Now, I need to confirm my beliefs and ask if my setup is good or bad. In my picture I have the VC line to intake now going to the catchcan and the PCV line ALSO going to the catchcan, the catch can is vented and the manifold plugged. I have a Dejon intake pipe without the nipples so I have no means to apply vacuum to the VC side.

Good or Bad?? If bad, suggestions are appreciated. I think from everything I have read I can get away with this or am I wrong?

what did you do to your manifold? is that painted and how long has the paint been on there?
 
Exhaust mani' paint been on there couple of weeks since the turbo replacement. Turns almost black when hot and returns to red when cold.:sneaky:
 
Should also mention this is a regular driver (not quite daily), but 3-4 days a week.:)
 
Your setup will work, however keep in mind that you have eliminated the circulation capability of the OEM setup. You might require more frequent oil changes because it will contaminate faster.
 
You also give your system no fresh air. In the OEM setup, the valve cover breather hose sucked fresh air in from the intake pipe under vaccuum.

Like he stated is correct, But, you also are taking in Unmetered air from that filter on the side. Those usually come sealed, did you tap it? What did you do to the PCV?
You have left side of VC going to can, and the PCV to the other side of the can?

Yeah exactly right. Both the PCV and VC outlets go to a vented can. Nothing else. As far as the vent on the can, I just removed the plastic view tube to clean it up and plugged the bottom and put a nipple on the top and slid a breather onto it. I can drain the can via a nipple valve on the base (can't see it in the pic), but figured this was neater than the silly little plastic tube.

The reason I'm asking about this setup, my experience leads me to believe I'm fine, but having read countless threads as to single and double can setups I began to wonder. Most single can set up seem to keep the OEM method from the PCV and the can in line with the VC side, but still drawing from the intake to create vacuum. My biggest dilema as to this setup is that I did this right after a turbo install and as you can see from the pictures UICP and intake as well. No other mods to the system and I now have a fairly significant oil weep from the exhaust camshaft seal. So I was wondering if this set up is causing some back pressure and pushing oil out of a weak seal:confused::confused:

Anyway, it might be pure coincidence but thought I'd ask those of you who have down the single can set up.:thumb:
 
Forgot to mention if it's not clear:ohdamn:

The PCV is brand new and still in place, with a hose running to the can and the manifold side is plugged. Should I remove the PCV or reconnect it? I didn't quite get what you were aiming for in asking what I have done to the PCV.
