Fully resolve typical crankshaft failure faults

• Continuous loud knocking impact noise from engine crankcase after startup
• Noticeable vehicle shaking during acceleration and hill climbing
• Dashboard oil pressure warning light stays illuminated persistently
• Scratched journal surfaces accelerate wear of main and connecting rod bearing shells
• Fatigue cracks on counterweights bring hidden danger of crankshaft fracture and engine stall
• Worn timing gear teeth trigger ECU engine timing malfunction fault codes

Rigorous multi-stage factory testing & sufficient spot stock
