Failure Symptoms

Initial signs of failure might include visible cracks or looseness of the cap, allowing moisture or debris to enter. If left unaddressed, this can lead to contamination of sensitive engine parts, potentially causing wear or corrosion. Continued operation with a compromised seal risks damage to internal engine components.

Installation Tip

Ensure the mounting surface is clean and free of any debris or old sealant before installing the new cap. Press the cap firmly into place to ensure a secure and tight seal.

Service Note

Inspect the surrounding area for any signs of damage or wear that might affect the sealing of this cap.
