How to Replace the Oil Filler Neck and Filler Seal on an LR3
The LR3 and RRS oil filler tube seal is located on top of the engine. It is replaced by removing the engine cover and then removing the oil filler tube. The oil filler seal is sold as a complete assembly which includes a new oil filler cap, new oil filler tube and a new oil filler seal. The seal is an o-ring and will wear out and allow a small oil leak to form on top of the valve cover. This oil filler tube should be identical on 2005-2009 Land Rover LR3 with the 4.4l V-8 and the Range Rover Sport of the same generation.

The tube is removed by prying up a tab at the base of the tube and then unscrewing the tube counter-clockwise.
