Symptoms:
- Rough idling and loss of power
- Excessive smoke from the exhaust (black or blue)
- Engine warning light illuminated
- Increased oil consumption or oil leaks
- Difficulty starting or misfires

Diagnosis:

- Inspect the EGR (Exhaust Gas Recirculation) valve for clogging or malfunction
- Perform a compression test to detect cylinder wear or injector issues
- Scan for fault codes related to fuel injectors, glow plugs, or sensors
- Examine the timing chain for stretch or wear, which can cause timing issues

Fixes:
- Replace or repair the turbocharger if damaged or worn
- Clean or replace the EGR valve to restore proper exhaust flow

- Repair oil leaks by replacing seals or gaskets, especially around the valve cover and oil cooler
- Replace the timing chain and associated components if wear is detected to prevent engine damage

Prevention:
- Use high-quality diesel fuel and change fuel filters regularly to protect injectors
- Perform regular oil changes with manufacturer-recommended oil to maintain lubrication and reduce wear
- Periodically clean the EGR system to prevent clogging and maintain emissions performance
- Avoid prolonged idling and harsh driving to reduce stress on the turbocharger and engine components
