This is the sump (oil pan) gasket, part number LVF500040, designed for Land Rover Td5 2.5L diesel engines. It seals the mating surface between the oil pan (sump) and the engine block, preventing oil leaks from the bottom of the engine. It fits the Defender Td5 and Discovery 2 Td5 FAQHow do I know this is the correct sump gasket for my Td5?Verify your engine is a Td5 with the “late” sump configuration and that the engine VIN is ≥ 4A000001. Compare the gasket shape or part numbers. Do I need any sealant or adhesive with this gasket?Usually, the gasket itself is sufficient, but a thin coat of RTV silicone or sealant on the corners is sometimes used as a precaution, per workshop practice. How often should this gasket be replaced?Whenever the oil pan is removed (e.g. for repair, cleaning, or inspection). Also replace if you observe oil seepage or leaks at the pan joint.
