🔌 Function

Forms the engine's main structure, carrying the cylinders, crankshaft bearings and all mounted assemblies.

⚠️ Common Signs of Failure

• Cracking, often between a bore and a coolant passage
• Main bearing bores worn, oval or misaligned
• Liner seats corroded or eroded
• Coolant leaking externally or into a bore
• Deck face out of flat, causing repeat head gasket failure

🛠️ Service Notes

• At 257 kg this is a crane lift and the largest single component in this range
• A replacement block is a full engine rebuild in practice — cost it against an exchange engine before committing
• Have the block crack-tested and the bores and deck measured before building it up
