| Symptom | Possible Cause | Correction | | --- | --- | --- | | Hard start, white smoke | Low compression (worn rings/valves) or retarded injection timing | Perform compression test; check timing marks on injection pump drive. | | Knocking noise, worse when warm | Pistons contacting pre-chamber (carbon buildup) or worn big-end bearings | Remove injector, use borescope to check piston crown; inspect rod bearings. | | Oil pressure low (<0.8 bar at idle) | Failed pressure relief valve or worn main bearings | Replace relief valve spring; check main bearing clearance. | | Black smoke under load | Over-fueling (stuck injector) or restricted air intake (turbo wastegate stuck closed) | Test injectors; check turbo actuator and air cleaner. |
