Q: Where is the PCV valve located and how can its functionality be checked on Honda Del Sol?
A: The PCV valve is in a breather hose connecting the crankcase and intake manifold. To check it, squeeze the PCV hose with pliers while the engine idles. Listen for a click from the valve, indicating it's working. If not, replace it. The valve is below the fuel injector rail in the intake manifold. To remove, pull it out of the grommet, detach the hose and note its position. Ensure the replacement valve matches your vehicle and engine size. Installation is the reverse of removal.
