🔌 Function

Closes off the inlet manifold aperture and seals it against the pressurised charge air.

⚠️ Common Signs of Failure

• Whistling or hissing under boost
• Oily or sooty film escaping around the joint
• Charge air pressure lower than expected and poor pull under load
• Sealing face pitted, corroded or distorted
• Bolt holes elongated or the fixings repeatedly loosening

🛠️ Service Notes

• Renew the gasket or sealing ring whenever the cap is removed, and tighten evenly from the centre outwards
• Check the sealing face is flat before fitting, as a distorted cap is the usual cause of a boost leak that returns
