- Examine ignition components for wear or damage, including spark plug condition and coil functionality

Fixes:
- Replace valve cover gaskets and camshaft housing seals to stop oil leaks
- Service or replace ignition coils and spark plugs to resolve misfires and rough idling
- Repair or replace faulty water pump or thermostat to address overheating issues
- Clean or replace fuel injectors if clogged or malfunctioning
- Perform routine tune-up including air filter, fuel filter, and oil change to maintain engine health

Prevention:
- Regularly inspect and replace aging gaskets and seals to prevent oil leaks
- Follow scheduled maintenance intervals for ignition system components
- Use high-quality engine oil and change it at recommended intervals to protect engine internals
