1. Inspect all eight fuel injector hold-down clamps for a broken ear.

2. If any broken ears are found, replace the clamps(s), re-seal the affected injector(s) and replace the injector-to-valve cover seal.

3. Pry the injector-to-valve cover seal out of the valve cover using a screw driver. The new seal can be installed using a 22 mm socket (rolling/pressing the seal in place).

4. Inspect the fuel injector return hose connection at the injector(s) for damage and replace if needed at this time.
