White steam from crankcase breather. | Use Cummins CC2602 coolant conditioner at double the standard dose for the first 500 hrs after liner replacement. | | Turbocharger VGT Ring Sticking (Tier 4 only) | Overboost at low RPM, then derate. | Manually cycle the VGT actuator with Insite software weekly during low-load operation (e.g., shovel standby). | | High-Pressure Fuel Pump (HPFP) Seizure | Sudden engine stop. Metal flakes in fuel filter. | Install a 10-micron absolute pre-filter before the factory 30-micron filter. Cummins will not void warranty if flow rate is maintained. | White steam from crankcase breather

When a QSK60 stops, operations stop. Downtime for a haul truck or a drilling rig can cost tens of thousands of dollars per hour. This is precisely why the is the single most critical document in any maintenance facility that handles this engine. Guessing, using generic procedures, or relying on memory is a recipe for catastrophic failure.
