The PCV isn't stuck to the grommet as it does turn. I've been trying to pull it straight out but guessing the grommet is dry rotted and doesn't give.The Pressure Control Valve (PCV) should pull straight out of the grommet. Give the top a slight twist to break it loose from the rubber grommet - squirt a tiny bit of WD-40 onto the PCV itself, and let it work into the grommet if you need to. Don't twist too hard or fast, though - you don't want to snap off the plastic part and leave the rest stuck in the valve cover.
Do the same with the plastic part and the hose - be careful not to snap it off... those things can get brittle after awhile.
I'm guessing you have a new grommet seeing how chewed up that one is. I'd recommend using a new one when you put the new breather in.
Hope that helps!
There is a twist in PCV cover on the drivers side, but that one which I'm leaving connects to the new intake manifold.That appears to be the vent to supply fresh air for the positive crankcase ventilation system. The elbow
are readily available. I've seen similar parts in the Help section of parts stores.
The PCV valve should be in the cover on the driver side.
You can read about the need for crankcase ventilation here:
Anything is possible.Maybe someone applied PVC glue to the PCV grommet...
I would put some oil on it and inside the grommet first.I'll be removing the valve cover tomorrow to remove the PVC from the inside of the cover and hope to replace it with no problems.
