PCV question, need help?

I was just on the appearance board and noticed a picture of a engine bay with the pcv on the passenger valve cover connecting to the tb. I quickly realized that that is the stock location. However my motor had been apart for so long that I had forgotten that when I rebuilt it. I installed a K&N valve cover breather on the passenger vc, and the regular pcv on the drivers vc. I connected the pcv to a vacumm port on the plenum.

My question is this.....did I do that right? Because I have taken away one of my pcv's, should I run the drivers side back the tb? Or did I do it right by running it to the plenum?

Thanks.

The PCV valve on the left (driver's) side should be connected to the vacuum fitting near the rear of the plenum. The breather fitting on the right side should be connected to the vent hose at the TB.

Using a breather type filler cap without the hose connection to the TB will cause airflow measurement problems for the MAF. You haven't "taken away" a PCV, but have allowed the PCV source air to be unmetered, probably causing lean mixture.

The stock setup should be similar to this:

Has anyone else had this problem when switching to a different style valve cover??
