To remove the PCV valve from a 2004 Chevy Avalanche, first locate the valve, which is typically found on the valve cover. Disconnect the hose attached to the PCV valve, then gently twist and pull the valve out of its socket. If it’s stuck, you may need to use a pair of pliers. Once removed, you can install the new valve by reversing the process.
