🔌 Function

⚠️ Common Signs of Failure

• Cracks, porosity or leakage from the casting
• Cylinder-bore wear, scoring or distortion
• Low compression, coolant contamination or excessive blow-by
• Damaged main-bearing saddles or threaded holes
• Deck-face damage or repeated head-gasket failure

🛠️ 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
