Where exactly is location of PCV valve? on 1992 Chevrolet S10

I have an oil leak into my air filter and have been informed I should change the PVC Valve. I purchased and now can not find the old part to replace. Is it hidden from top view?

Asked by for the 1992 Chevrolet S10
The PCV valve is located on top of the valve cover. Chevy actual had a recall on the valve as it was seizing up in cold climate areas. Valve should be under $10 and simple to replace. Its toward the rear of the engine just around where the air snorkel passes over the valve cover.
Sounds simple enough but I still can not locate it. I have disconnected the hose that seems to be the one pointed out but no luck. Now I am gently pulling the piece that was in the hose but I do not want to break anything so I am not pulling hard. I have a photograph of my engine and the part the auto store sold me. Anyway I can upload the photo?
I've been having the same problem and finally found this on another website:

"I have a 1992 chevy S10 with a 4 banger and I've spent the six years I've owned it trying to find a PCV valve. I have always been too embarrest to ask anyone. I even bought one six years ago and it is still in the glove box!!! Finally one day I asked my father who has owned a chain of auto parts stores for 40+ years to try and find it. After laughing at me for a while, I finally asked him to show me where it is. What do you know... he couldn't find it either. This sparked a long research through all his parts books, and finally he found a foot note that mentions "most S10's of this vintage use a very common part #blah blah... but very few were built without PCV's" I guess you and I have one of those "very few.""
Yep, I finally had a mechannic look at it. Actually I was in the shop about to leave when I remembered so I asked the guy to quickly show me the PCV. In just a few minutes there were three of them looking. Finally I know this truck does not have one nor a spot to put one.
AH HA!!! I thought my truck was the only one with NO PCV valve!WHEW! Mine is 93 S10 Sonoma, 2.5lt, 5 speed...I did the same,about 5 yrs ago, bought all the tune up stuff, air/fuel filters, plugs,cap,rotor...PCV valve...& its NO where to be found! Ive talked to a number of ppl,mechanics at GMC!! & they look at me like im dumb! Just cause Im female, DOESNT mean i dont know my way around an engine!I still have this PCV valve, also in my glove There isnt even a place to put in in the valve cover, so i guess this lil truck just isnt meant to have one! Thanks for confirming im not crazy! I recently purchased another identical truck..& go figure, IT HAS a PCV!! Makes no sense to me! UGH!
