== == I'm not sure. I have a 2000 S10 4cyl. and I can't find the PCV valve. The only thing coming out of the valve cover is a short 90deg. hose that connects to the air intake box. Does this engine have a PCV valve? I'd appreciate any info.

== == I don't know about the 2000, but the 94, the PCV valve is underneath some throttle linkage. At the front of the engine, you'll see the radiator hose, then an AC line, and underneath a plastic shroud, you'll see another hose. Take off the plastic shroud by removing the screw at the top of the shroud. The PCV valve is held in by a screw fitting, back it off and you'll find the PCV, pull it off the hose attached to it and replace.
