Engine M272.965

Symptoms:
- Rough idling and misfires
- Loss of power and hesitation during acceleration
- Check Engine Light (CEL) illumination
- Oil leaks around the valve covers and camshaft adjusters
- Excessive oil consumption
- Timing chain rattle noise on cold start

Diagnosis:
- Inspect ignition coils and spark plugs for wear or failure, common causes of misfires
- Perform a compression test to rule out internal engine damage
- Check for oil leaks around valve cover gaskets and camshaft adjuster seals
- Use a diagnostic scanner to read fault codes related to camshaft timing and misfires
- Listen for timing chain noise indicating possible chain stretch or tensioner failure
- Inspect variable valve timing (VVT) solenoids for clogging or malfunction

Fixes:
- Replace faulty ignition coils and worn spark plugs to resolve misfires and rough running
- Replace valve cover gaskets and camshaft adjuster seals to stop oil leaks
- Clean or replace VVT solenoids to restore proper camshaft timing function
- Replace timing chain and tensioners if excessive noise or timing errors are detected
- Address oil consumption by repairing leaks and ensuring proper oil level and quality
- Reset fault codes after repairs and perform a test drive to confirm resolution

Prevention:
- Regularly change engine oil and use manufacturer-recommended oil grade to prevent sludge buildup and VVT solenoid clogging
- Replace spark plugs and ignition coils at recommended intervals to maintain ignition system health
- Inspect and replace valve cover gaskets proactively to avoid oil leaks
- Monitor engine performance and address any CEL warnings promptly to prevent further damage
- Use quality fuel and avoid extended idling to reduce carbon deposits and maintain engine efficiency
