Where is the PCV located on a 2000 Chevrolet S10 4.3L?
Passenger side valve cover
The PCV valve is just to the left of the carberator...if your looking at the carb. follow the hose comming out of the center of it (should be rubber and hard plastic combo) that plugs into the PCV valve. I believe the answer is that it does not have one...I have a 2000, and it doesn't have one......
The 4 cylinder has the PCV located under a threaded cap that is screwed into the valve cover on the back side. You will need to remove the vacc. hose from the cap and then unscrew the cap and remove the PCV from the hole that is opened up and replace the valve and install the cap and hose. It will be oil covered and that is normal.
