Try it first. Cheapest fix if it works. Search around here, there tons of info on that.
Lazy way:
Gut the pcv valve, reinstall in manifold, attach hose and run to catch can. Then run the valve cover breather hose to another port on the can too. Plug the port on the manifold where the old pcv hose went. Plug the intake pipe port where the VC hose went. Hopefully your can has a breather filter on it.
Theres a better way where you keep the pcv valve in tact, but the writeup was on ohmt. I dont know if it made its way over.
I saw another writeup using the exhuast to draw the pressure out, like old v8 guys do. Probably the best way but the most cost/labor involved.
