What to Look For

• IMS (Intermediate Shaft) bearing failure — catastrophic if it fails
• Bore scoring / cylinder liner cracking (Nikasil or Alusil)
• Rear main seal (RMS) oil leaks are common
• D-chunk coolant pipe failure causes overheating
• AOS (Air Oil Separator) failure leads to excessive oil consumption

Pre-Purchase Checklist

• IMS bearing — ask if upgraded (single-row to dual-row or ceramic)
• Bore scope all cylinders for scoring or flaking
• Check for coolant loss or overheating history
• Listen for engine knocking or ticking at startup
• Inspect RMS area for oil seepage
• Verify service history — these engines need regular maintenance
