After another head gasket has blown (ML metal type) in about 2 years, I decided to go for a genuine one.

Trouble is, the main dealers says that they have 10 on back order that are not expected until the end of July…

I can’t find any after a Google search. Does anyone know where I can get my hands on one please? Or maybe I need to search the make of the genuine one?

I need my truck for work, so an option is to go ahead and fit the non genuine one I have, but I’d rather not.
