A bad PCV valve can produce a number of symptoms:
For example, if the valve gets stuck in the closed position or clogs, you'll notice one or more of these symptoms:
* Increase in internal engine pressure * Failure of one or more oil seals or gaskets * Engine oil leaks * Moisture and sludge buildup inside the engine * Engine surges and possibly black smoke
If the PCV valve gets stuck opened, or a system hose gets disconnected or ruptured — producing a vacuum leak — you'll notice one or more of these symptoms:
* Engine misfires at idle * Lean air-fuel mixture * Presence of engine oil in PCV valve or hose * Increase oil consumption * Hard engine start * Rough engine idle The fix? Remove and clean or replace the PCV valve.

Just had a look in my valve and there is nothing in it. Just a small hold which then goes to the crankcase via a brass pipe??

Good morning.
No cone-shaped valve and no spring huh? Your best bet is to hunt up a NOS unit. I realize where you are it may prove difficult to find one. Try RFJP(G503) or Peter DeBella Jeep Parts to start with. They pop up on eBay every so often. Beware. There are some ersatz versions out there that can not be disassembled. I’ll do some looking for you and see what I come up with. May not be today as I’m booked up solid through the weekend, but I’ll look.

Is there a god way to test these pic valves? Seems to me that the valves play such an important part with regard to engine idle quality that there should be a good way to test there functionality. Something is giving me fits trying to smooth out the idle on my 62 134F. I've been chasing a "vacuum leak" and I'm beginning to believe it may just be the egr system. My valve is clean but doesn't "rattle" when shaken.

It should rattle some. Were you able to disassemble it and clean it? Sounds like time to replace it with a quality NOS unit. Ron Fitzpatrick, D.L.Bensinger or Peter DeBella.
