trying to figure out a catch can setup for my soon to be turbo b18b. Now i saw all the billion how to's, but they all seem to be on b16's and b18c's...i have not seen one on a b18b.

How exactly would I do this on my b18b? I have the PCV valve in the middle of the valve cover going into the IM. Would I just hollow out the PCV valve, run a line to a catch can then another line from the catch can into the IM, then just put a filter to vent the valve cover where I currently have a line going from the intake to the valve cover?

Or would I just leave that PCV setup and vent the block like all the other how-to's are with the OEM block fittings running to a vented baffled can?

 

On a boosted setup, you really want an open breather can. Ideally, you want to run the block fittings and then close up the vent on the valve cover.

Here are some good threads about PCV evacuation on a boosted motor:

Ok, but what exactly do I do with my PCV valve then? If i run the block setup with the vented can I still have my b18b PCV valve setup in the valve cover.

 

Here is what im talking about, if I do the block venting, do i just leave that PCV valve there going to the Im, then that other red line is the vent that goes into the stock intake, just slap a small filter on there?

 

I would plug it. There is no reason to have the stock PCV valve if you have an open breather run from the back of the block.
