I need to replace mine also. Are there generic ones available at the auto parts stores (AutoZone, etc.), or should I get one from Isuzu?

hm i was out there a day or two ago and changed my pcv.. had a purolator in there and noticed that the top and bottom had started to separate, there was like a 1/8" gap in the elbow, anyone else seen this?
Next time you replace the PCV valve, it's probably a good idea to replace the grommet also. It's been prone to deteriorate over the years. You won't notice it from the top. The center part will separate and one day the bottom half will drop down inside the valve cover when you pull out the valve. It probably won't go far and you can easily grab it with tweezers or whatnot, but why not just change it now. You can get a replacement at many parts stores for a few bucks. At Pep Boys, the Help grommets are right by the PCV valves.
I used #42340 and it fits perfect. Others have also used #42330.
