- Replace worn gaskets and seals to stop oil leaks; perform regular oil changes with recommended grade oil

Prevention:
- Regularly check and maintain coolant levels; flush and replace coolant according to service intervals
- Follow timing belt replacement schedule (usually around 60,000 to 100,000 km) to avoid belt failure
- Use quality spark plugs and replace them at recommended intervals to prevent misfires
- Monitor oil levels and change oil and filter regularly to ensure proper lubrication
