Valve Cover Oil Leakage

[firetwuck]

I'm sure there is an easy answer to this questions... I am noticing more oil leakage out of the top of my valve cover. Any ideas what is causing this and what the solution would be?

replace the PCV valve and the grommets in the valve cover. The oil and gases that they experience harden the rubber and make them ineffective over time. AZ's heat, and the ethanol fuel we have kills rubber faster.

I knew it was an easy answer. Do I need two PCV valves then?

Is a little leaking normal? Mine's always done it, not as bad as firetwuck's, but enough to notice that it's dirty.

You need only one PCV, the other is a fresh air return hose, no valve there.

Hi again guys, thanks for all the input. I take it that the one closest to the front is the PCV and the rear one is the air return. One thing though, I went to Autozone and Checker, neither of their systems say that they carry a TJ PCV valve. Is this a dealer only item?
