Turbocharger GT1752S – Symptoms of Failure

Vehicle: Nissan Patrol / Nissan Safari
Engine: 2.8D RD28TI (78 kW / 95 kW)
Turbo model: GT1752S

The GT1752S turbocharger fitted to the Nissan Patrol / Safari 2.8D RD28TI engine is designed for durability, but over time it may fail due to oil contamination, high mileage, overheating, or heavy off-road use. Below are the most common symptoms of turbocharger damage:

1. Loss of Engine Power

• Sluggish acceleration
• Weak boost pressure
• Poor performance under load (especially uphill or towing)

2. Excessive Exhaust Smoke

• Blue smoke – oil leaking through worn turbo seals
• Black smoke – insufficient air supply / boost loss
• White smoke – possible oil entering exhaust side

3. Unusual Turbo Noises

• Loud whistling or siren sound during acceleration
• Grinding or metallic noise (damaged bearings or shaft play)

4. Increased Oil Consumption

• Frequent oil top-ups required
• Oil present in intercooler hoses or intake piping

5. Oil Leaks Around Turbocharger

• Visible oil at compressor or turbine housing
• Oil dripping from turbo area

6. Boost Pressure Problems

• Underboost condition
• Slow turbo spool-up
• Engine entering limp mode (if equipped with boost control system)

7. Excessive Shaft Play

• Noticeable radial or axial movement of the turbo shaft
• Possible contact between turbine wheel and housing

Common Causes of Turbocharger Failure

• Infrequent oil changes
• Low-quality engine oil
• Blocked oil feed or return line
• Engine overheating
• Foreign object damage (dust ingestion in off-road conditions)

Recommendation

If your Nissan Patrol / Safari 2.8D RD28TI shows any of these symptoms, inspect the turbocharger immediately. Continued driving with a failing turbo can lead to engine damage or complete turbo failure.
