Rocker cover double layer?

[Lyngeled]

Hello
Anyone knows why the rocker cover on the Renault crossflow has a double layer? I know that you have many different engines and that it is a little weird question. Anyway there is a extra metal sheet on top of the first and oil and dirt can hide in there. I am considering filling up the gaps to make it look nicer and paint it.

Cheers

Hi Bobbie, can you forward pictures? It would be easier for us to help if we can see the issue.

This is the best I could find.

To quiet down the noise from the valve train.
