Mitsubishi Xpander Oil Leak Malaysia
Common oil leak points on Xpander: valve cover gasket seepage at 80,000+ km (very common on 4A91), camshaft oil seal, and PCV hose cracks causing oil mist in the intake. Leaks present as burning smell from engine bay or dark stains under the parked car. Address promptly — oil on exhaust manifold is a fire risk and oil loss accelerates chain wear. Valve cover gasket is an inexpensive repair.
