I have a 2006 L 33 with a TVSS intake manifold and throttlebody(DBW). I just switched back to DBW. When I had the cable throttlebody, I had a hose running from the port on the throttlebody to the barb on the valvecover. The DBW throttle body does not have a port for PCV. How should I route things and what should I do about the barb on the valve cover? The valley cover does not have a barb on my set up.

 

If it was the manifold vacuum port, find a source on the back where there might be a port.
If it was the fresh air port, any source BEFORE the throttle butterfly will work.

 

I believe it was the fresh air port since it was coming right from the throttle body before. I can drill a hole in the intake tube and run a line from that with a fitting. For some reason, I have a mental block when it comes to PCV

 

In case you haven't seen it there's a sticky thread called "does my catch can routing look ok" that has a TON of information in it.
