How to remove my PCV valve
My pcv valve is the plastic 90 deg version. However it definitely feels as though it has threads. So, I attempted to remove it by unscrewing it out. However, after at least 75 rotations it isn't coming out. Can I be mistaken that it doesnt have threads? It sure looks and feels like it does. I'm afraid to just pull it out. Any thoughts on how to remove it?

It is not threaded in there. I though the same thing. I used a nice set of channel locks to get it out. I would also suggest replacling the rubber grommit as well. One huge tip that I can give you is on the grommit removal without it falling into the valve cover. It is a royal pain in the *** to fish the grommit out if it falls in there,
I am replacing mine again tomorrow and I intend to try this out.
Fishing line and a hook large enough to dig into the grommit. This way if it falls into the valve cover, you just pull it back out. Hope this helps.
As for getting the PCV out, it does take some force. Gloves are reccomended to help those knuckles out .

99 is definetly not screwed in. I had a 99RX and it is in a rubber gromment which has probably become very brittle and hard. Be very careful....probably a good time to replace the gromment as well....Folks have broken the gromment and it does fall in...

I am one of those folks. Not a fun retrieval

Thanks guys. I though of checking the pcv valve to see if it may be clogged. I have oil leaks from the valve covers and wanted to rule out the PCV valve before I replace the PITA rear valve cover gasket.
Now I'm worried about the grommet falling down into the valves. The PCV valve does look fairly new though. I'm suspecting that it's been recently replaced. I bought tha car about two years ago. Should I go ahead and remove it anyway?

Why dont you do a insitu test.
Remove the oil filler cap and place a paper and see if the vacuum tries to suck the paper in ... (not a sure test)
Other is to connect a clean hose on to the valve and try blowing and sucking through it (not sure what the long term health consequences are but once in so many years ought to be fine).
Grommet: [Caution it may not be right for you]
My experience is the problems happen due to uncontrolled events. I prefer making a surgical cut and then pulling the piece out. The thing falls down due to elastic nature of the rubber as it breaks away from the lip and it your hold on it is loose.

Thanks Salim,
I like the idea to try blowing/sucking on a hose connected to the PCV. I'm thinking the PCV valve is fine. The engine idles perfectly and runds smooth. I have a new OCV right side on order and will put that in this weekend to solve another problem I'm having.
It's the darn oil leak that I'd like to cure.
