Mitsubishi Eclipse Cross Valve Cover Gasket Replacement Malaysia
The valve cover gasket (rocker gasket) on the 4B40 engine seals the top of the engine against oil leaks. Over time and with heat cycling, this gasket can harden and begin to seep oil — typically noticed as an oily residue around the top of the engine or a burning oil smell from the engine bay. Replacement is a straightforward job and the gasket is an affordable part. Delaying this repair allows oil to drip onto hot components, creating a fire risk.
Eclipse Cross Valve Cover Gasket
- Turbo heat cycling stresses valve cover gasket — inspect at 80,000 km for seepage
- Oil dripping from valve cover onto turbo or exhaust manifold creates smoke and burning smell — do not ignore
- Genuine Mitsubishi gasket set recommended — silicone compound quality matters for long-term sealing under turbo heat
