Need help with Holley valve covers Hello, I recently put on a set of the red Holley valve covers on my 2000 Z28. They look good, the problem is the lack of ports for the PCV system. What are people doing about this? I wouldn't be opposed to running a catch can if I have to, I would be fine with either way. I'd love some input on this, what goes where, what parts do I need, etc. Thanks in advanced. Also, I wasn't sure where to post this so sorry if this is the wrong place.
Each VC has a 3/8 hose end correct?
Install the driver side pointing to the rear of the car and the passenger side pointing to the front. On the one from the driver side you'll run a 3/8 hose around the back of the motor and up along the passenger side of the intake where you could run it into a catch can then out of the can through an inline PCV valve or you can find a way to make the one in the stock line work and connect it to the intake manifold. The passenger valve cover you would connect a 3/8 hose from it to the port on the throttle body or in the bellow between the MAF and TB.

This is the stock setup and the passenger valve cover had two ports instead of one. Notice the PCV valve at the end of the hose just before going into the intake manifold? You don't have to run a sealed catch can but it will help slow down some of the blow by from getting into your intake manifold.
