Mazda CX-90 Oil Leak Malaysia — Inline-6 PHEV
CX-90 3.3T is a new engine — oil leak patterns not yet established in Malaysia. Common potential points (general inline-6 PHEV): turbocharger oil supply and return lines, cam cover gaskets (6-cylinder has longer gasket runs), front and rear main seals at high mileage. PHEV-unique: electric motor housing oil seal (gear oil) — if motor oil leaks, it appears near the front drive unit. Any oil leak requires prompt diagnosis — new platform means parts lead times may be longer.
