Toyota Rush Oil Leak — Common Sources

Rush petrol engine common oil leak points: valve cover gasket (most common, gasket hardens with age — RM 100–180 to replace), camshaft position sensor O-ring, crankshaft front seal. The valve cover gasket on 2NR-VE can start seeping at around 80,000–100,000 km — you'll notice oil smell after engine warmup and possibly slight smoke from the engine bay. Fix promptly — oil on hot engine components can cause fire.

Common Toyota engine oil leak points: valve cover gasket (most frequent — brown residue on top of engine), camshaft oil seals, crankshaft front seal (oil on timing cover), and the oil drain plug (overtightened at previous service). For Hilux/Fortuner diesel, also check the turbo oil feed and return lines. Any oil leak in the timing belt area on belt-driven engines is critical — oil-soaked belts snap. Valve cover gasket replacement costs RM 120–250 at independent workshops.
