Hi Everyone,

I needed to remove the engine cover on my 2009 Autobiography and discovered that there should be a washer between the top of the "Engine Cover Mount Stud (part # KKN500061) and the bottom side of the engine cover.

From what I can see the cover has a grommet in the mounting hole and this washer is held in place by the cylindrical part sticking up (sorry about the poor description).

Here are a bunch of photos of this small washer.

Have you considered a disc spring nut or a large flanged nut, which would get very close? 2015 Range Rover Autobiography 4.4 SDV8

Hi Everyone,

I found the answer! It turns out that this washer slid into a rubber grommet in the appearance cover. I just happened to stumble upon a, “M6 Rubber Grommets Bolt” on Amazon and it’s the actual grommet with the top hat washer. I guess in this application it’s called a, “Grommet Bolt.”

The new one is a bit thicker but works perfectly. Original is on the left in this picture.
