I have a Mini (R56) with the N18 engine, I need a new PCV and valve cover gasket, so I thought I would just get a new valve cover since everything I need is included in the cover (plus its plastic and will crack eventually) . I have the option of a metal valve cover from Bremman Parts, a plastic one from bremman parts, or a plastic one, but its the Genuine PSA part that is the same as the genuine mini part but alot cheaper. (They’re the exact same engine in the Mini and Peugeot)

Which is better and which one should I get?
