Does a Chevrolet S10 pickup have a pcv valve for a 4 cylinder?

I I have 98 s-10 with the 2.2 4 banger. I went to auto zone to do the first tune up on it a few years ago, and like aways that was on my list of things to get. They have the part number for it in the book, but they did not have one on the shelf or even a place for it on the shelf. So then me and my friend looked at my truck, and we could not find one for anything, so im kinda going with that it does not have one, unless its not located in the ussual place, on top of the valve cover.

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."

I had an '88 Jeep commanche pickup that had a massive oil leak on the top end when I bought it. At 65mph on the highway I blew out 6 quarts of oil in 20 miles of driving. I pressure washed the engine, started my tune up and found it had no PCV valve. I checked the books and the jeep uses a sealed crankcase system, even the oil fill cap has a gasket and it tightly screwed in place. I drilled a hole in the valve cover, installed a grommet and PCV valve, and spliced into a vacuum line to the intake manifold and never had another problem with oil leaking after that. I now have a '96 S-10 that has a valve cover leaking, looked for a PCV valve and cant find it. Looks like i'm drilling another hole.
