Premier Sump plug washer Fits Land Rover Range Rover L405 WESTMINSTER D350 [11/2020 to 11/2021] (3.0L 183kW AJ20D6 6 Cyl DOHC I/C Turbo CRD)
Today I bought a pack of 10 sump plug washers/o-rings which supposedly are suitable for the D250/D300/D350 engines in the various LR models. Supercheap also list PWR14R-10 as special order which might be the same and are a little more expensive. The lack of a vacuum extraction tube means that the sump plug has to be removed for every oil change and buying a complete plug seems an unnecessary expense.
The seal is an o-ring with webbing to keep the o-ring centralised on and attached to the bolt.
