Cometic Valve Cover Gasket Kit for Mitsubishi 4G63 / 4G63T

The Cometic C4691 Valve Cover Gasket Kit is a premium sealing solution designed specifically for Mitsubishi 4G63 and 4G63T engines.

Unlike traditional cork or paper gaskets that are prone to leaking, drying out, and failing under heat and pressure, this gasket features a soft durometer rubber wrapped around a steel torque-limiting frame. This advanced construction provides superior sealing performance, excellent reusability, and resistance to blowout, over-tightening, and high vacuum.

Whether you're performing a routine valve cover service or building a high-performance 4G63 engine, this gasket delivers reliable, long-lasting sealing that outperforms standard replacements.

Key Features

  • Steel Torque Limiting Frame – Prevents over-tightening and maintains consistent compression
  • Soft Durometer Rubber – Excellent conformability and sealing ability
  • Superior to Cork/Paper Gaskets – Resists blowout, drying, and vacuum leaks
  • Extended Reusability – Can be removed and reinstalled multiple times
  • High Heat & Pressure Resistance – Built for both stock and high-performance applications
  • Precision Fitment – Engineered specifically for Mitsubishi 4G63 / 4G63T engines
