Toyota Yaris Oil Leak Guide
Yaris common oil leak: valve cover gasket and crankshaft front seal. Small-displacement engine leaks are inexpensive to fix — don't ignore minor seeps.
Yaris Oil Leak — Common Seal Points
Yaris petrol common oil leak points: valve cover gasket (most common at 80,000–100,000 km), camshaft seal, crankshaft front seal, VVT-i oil control valve seal. The Yaris Hybrid has an additional seal point: the junction of the engine with the motor-generator housing. Oil leaks in the hybrid that contaminate the MG housing are more serious — they can damage MG1/MG2 insulation. Address any oil leak on the hybrid promptly. Valve cover gasket replacement: RM 80–150. Crankshaft seal: RM 250–400.
