Locate the PCV valve and loosen the hose clamp.

Remove the hose from the PCV valve. Replace the clamp and hose if they're worn, cracked or leaking.

Thread in the new PCV valve by hand to prevent damage to the fragile aluminum valve-cover threads.

Tighten the new PCV valve until it seats firmly in the threads. Do not over-tighten.

Replace the hose and clamp. Start the engine and test system for leaks.
