Would fitting a catchcan do away with the pcv valve all together?
Sorry, I looked around but we don't really have any info on that year because it wasn't available here. A catch can doesn't replace it.

bumping this because you took the time to take pics and this helped me out
FYI - Autozone P/N PCV1142DL works as well and you can use a 19mm deep socket to remove the PCV valve.
Unfortunately, it does take some time to clean the PVC valve and it does make sense to combine it with IC removal and clean up.
In order to avoid having to do all that, prior to each oil change, I disconnect the upper hose and spray liberally carb fluid cleaner or mass air flow cleaner. The fluid eventually precipitates on top of the PVC valve and cleans the PVC bulb well enough to make it functions as new. If the process is repeated with each oil change, I cant see how it will ever get clogged. I have not had any issues yet.
I recommend making it an annual maintenance item or prior to each oil change since it is easy to do.
