After doing some research and checking some threads ( mainly in the engine DIY section ) I see pretty much everyone is throwing a catch can between the pcv valve and the nipple coming off the lower part of plentum. Is just doing a catch can here sufficient or is there anyone out there using this design on the other valve cover as well ? Thanks Dave

 

I put one on the left side breather and no oil collected. So I took it off and put a K&N style 5/8 breather filter on. Less weight lol.

 

Gotta love the " light weight mod " lol, thanks for the responce looks like ill just do the passenger side.

 

the driver's side port on the back of the valve cover is the breather.

The PCV valve is built in to the nipple on the passenger's side valve cover. You can unscrew it and verify for yourself.

The catch can should go between the pass. side pcv nipple and the nipple on the lower plenum. the port on the lower plenum is where vacuum is pulled from.
