🔌 Function

The cylinder block forms the engine's primary structure and aligns the crankshaft, cylinders, lubrication passages and cooling jackets.

⚠️ Common Signs of Failure

• Cracking or porosity
• Distorted main-bearing tunnel
• Damaged liner seats
• Coolant or oil leakage through the casting
• Damaged deck or housing surfaces
• Severe internal corrosion or cavitation

🛠️ Service Notes

• Treat this as a machining and assembly job rather than a bolt-on part: measure the bores, main bearing bores and deck and work through the checks the workshop manual specifies for your engine before building
• Wash the block out thoroughly and blow every oil and coolant gallery through before assembly — a new block still carries machining debris and preservative
• Check that liners, dowels, core plugs and gallery plugs required by the build are present, correctly fitted and properly sealed
• Use new fasteners wherever the manual specifies them, and follow its tightening stages and sequence exactly for the main bearings and the cylinder head
• Confirm the block is the correct one for your engine's designation and serial number before any machining is started, and protect the finished faces from corrosion until assembly
