Nissan Serena Oil Leak Malaysia
Common Serena oil leak points: valve cover gasket (MR20DD at 80,000+ km), VTC actuator seals, crankshaft front seal at high mileage. Oil smell is noticeable to MPV passengers. Detect early — oil on exhaust creates fire risk. Check underside at each oil change.
Serena Oil Leak Diagnosis
- C27 MR20DD: valve cover gasket and cam seals most common leak points after 80,000 km
- Oil consumption above 1L per 5,000 km = internal seal issue — inspect soon
- Rear main seal: check if oil appears on bell housing area
- Fix leaks before annual service — prevents oil contamination of other components
