To change the PCV valve in a 1998 Pontiac Transport, first locate the valve, which is typically found on the valve cover or connected to the intake manifold. Disconnect the hose attached to the old PCV valve, then twist and pull the valve out of its socket. Replace it with a new PCV valve, making sure it fits securely, and reconnect the hose. Finally, start the engine to ensure proper installation and check for any leaks.
