Q: What is the location and replacement process for the PCV valve and hose?
A: To replace it, disconnect the hose, loosen the valve from the cover, then reattach the hose to the valve. While idling at normal operating temperature, put your finger over the valve. Shut off the engine and detach the PCV valve from the hose. Connect a clean piece of hose and blow through the valve from the valve cover end. If air will go through the valve in this direction, replace it.
