Mitsubishi Galant Fortis Oil Leak Malaysia
Oil leaks are common on high-mileage Galant Fortis units as rubber seals and gaskets age in Malaysia's heat. The most frequent sources include the rocker cover gasket, camshaft seals, and the crankshaft front and rear seals. A minor seep that only leaves a small spot on the driveway is less urgent, but any leak that is dripping actively should be addressed promptly to avoid oil loss and fire risk. The rocker cover gasket is the most common and accessible fix on this engine.
Galant Fortis Oil Leak Inspection
- High-mileage Galant Fortis (common in Malaysia): inspect valve cover gasket, cam seals, and rear main seal every 40,000 km
- MIVEC oil control valve seals: can leak on high-mileage cars causing oil consumption and MIVEC codes
- Prevention: strict 5,000 km oil change intervals with correct viscosity reduces seal degradation significantly
