Miata94 just go to any autozone or advance auto and tell them you need check valves. They have a display section. Get whatever fits your hose.
Not sure if you're being sarcastic or not. I got the catch can today and put it together. Tomorrow I was going to run and get some hose to route the lines and then a plug for the intake manifold. I was going to leave the PVC piece on there and then run a hose from it to the catch can. Then also the driver side port to my vented can and like I said, plug the intake manifold port. I hope that should be fine.

Why wouldn't I be serious?

The PCV valve is only there to prevent air from flowing into the valve cover. Since you're going VTA instead of to the intake, you don't need the pcv valve. You'll have more flow capability if you drill it out but unless you're running a shitton of boost you will probably flow enough.

The catch can thing perplexed me for a while but it's pretty simple. Essentially you just need big holes in your valve cover for air to escape. The car doesn't give a **** about the actual can as long as the air ends up VTA.
