What this part does
The cylinder head mounts to the top of the engine block, sealing the combustion cylinders to generate compression. It houses the intake and exhaust valves, camshafts, and spark plugs, while also containing internal passages for engine coolant and lubricating oil. When this component warps or cracks, usually due to severe overheating, it compromises the head gasket seal. This failure typically results in coolant mixing with engine oil, a total loss of cylinder compression, white exhaust smoke, and continuous engine overheating.

Before you order
Check which specific bank (Bank 1 or Bank 2) your engine requires, as BMW V8 cylinder heads are side-specific and not interchangeable side-to-side. Always have a machine shop verify the deck surface for perfect flatness before installation. Installation mandates the use of a brand new head gasket and new torque-to-yield head bolts, as the original bolts cannot be reused. It is highly recommended to inspect the valve stem seals and guides while the head is off the block.
