Land Rover Part Number: LGH000040 - Exhaust Valve - Cylinder Head - V8 - Black
LGH000040 is an exhaust valve fitted in the cylinder head of V8 petrol engines. The valve is a hardened, black-finished component that seals against the exhaust seat during the exhaust stroke to contain combustion gases and withstand high temperatures and pressures; the valve stem runs within the valve guide and works with the valve spring and retainer to return the valve to the closed position. Correct valve face condition and stem integrity are essential for sealing performance and correct exhaust flow characteristics. Related parts for removal and installation include the matching inlet valve LGH000030 and service items: stem seals ERR1782, valve springs ERR4628, spring caps ERC573 and cotters ERC1637 - replace matched components where wear or damage is present to maintain valve timing accuracy and sealing performance. The valve is used on V8 cylinder heads fitted to Discovery 2 and Range Rover P38 applications as shown below; confirm exact vehicle specification before ordering.
