Frequently asked questions

What is the CDU1001LLR sealing washer for?
It's a copper crush washer for the engine oil sump drain plug, used on the Td5 2.5-litre 5-cylinder turbo diesel. It seats between the drain plug and the sump pan, deforming as the plug is tightened to form an oil-tight seal.
Can the CDU1001LLR sealing washer be reused, or does it need replacing every time?
It should be replaced every time, since as a crush washer it deforms permanently to form the seal and won't reseal properly if reused. Fit a new one at every oil change so the drain plug seats correctly.
Which vehicles does the CDU1001LLR sealing washer fit?
It fits the Land Rover Defender up to 2016 and Discovery 2 (1999-2004), the models flagged for this part, specifically those fitted with the Td5 2.5-litre engine. Confirm your engine type before ordering, since petrol variants use a different washer.
