PCV grommet help

Going through some of the idle issue fixes on here. Went to pull the valve out and it crumble and the lower piece of the valve fell into the valve cover. Thank god for baffles. Anyway went to pull the grommet out and it wont budge. Will i need to break that out also. Every other grommet (hundreds) I have replaced were rubber easy in and out. Probably safe to say im in for a trip to O'Reilly for a grommet and valve cover gaskets?

Same thing happened to mine, but I was replacing the PCV and the valve cover gasket anyway. Both the PCV and the grommet had gotten very hard and had to be broken out in pieces.

Same thing with my 4.0. I pulled the valve cover and it had a one piece rubber silicon gasket so I was able to clean up the head surface and reuse the old gasket. Over the years and heat, the Pcv rubber Gormet hardens and has to be broken out in order to replace.

Same here. The rubber gets brittle and hard. It's breaks apart when you try to remove it.

I ordered a bunch of parts from Rock Auto and they had the PCV elbow and the rubber gasket for about $5.

Well. I got it all sorted out without having to pull the valve cover. I tried heat the grommet to see if it helped gettng it out. Haha came out in about a hundred pieces. Now I went with the more expensive BWD PCV valve and its ticking really bad. When you touch the valve itself you can actually feel it. Did I just get a faulty one. Cause I have never had this sound comng from any of the others I have installed

It's normal. It will calm down eventually. Its because it's so clean. Clogged PCV's don't make noise.

You have a picture of the rear pcv elbow? Something is missing on mine and idk what it is. The hard plastic line is just stuck back in the elbow but it easily falls out. Think i have the wrong elbow.

5.2 Hard PCV Grommet blues

I use a Dremal multi-Max- http://www.dremel.com/en-us/Tools/Pa...spx?catid=2094 To slice the Old and Friggin hard Grommet into quaters. If you are very carefull... You can remove the offending grommet and PCV valve with out dropping crap down into the valve cover. If you do not own one of these things, you have no idea of what your missing! The only thing that I have found more usefull in life, would be wd40!

So much easier on my 93... both CCV elbows use twist-lock fittings, not grommets.
