How do you know its leaking. What did you do to discover the leak?

Remove the hose, and hit the nipple with some hair spray, then quickly reassemble and tighten snugly.

I had the same problem with the oem pcv valve. Leaked at 10 psi. Bought a new one from Mitsu, and it leaked the same. Like you, I installed a check-valve between the pcv valve and the intake manifold. No more leak. That was about two years ago. I recently checked for boost leaks to 30 psi, and still no leak at the pcv!

Yea I tried a new valve and I could blow on it and it would sightly leak. So hopefully the kit I bought fixes it!

I bought a PCV valve from Advance Auto. It looked like an exact replacement but it leaked when I blew through it. I got my money back.

what would the symptoms of a leaky PCV be other than the obvious? Like driving symptoms.. would a leaky pcv affect the smoothness of a WOT pull?
