Unfortunately Elring doesn't specify what their 584.950 VCG is made of, but I assume it's the original HNBR.

Oh okay interesting! Might try it out next time my OFHG is due..

But yeah for the valve cover gasket, since the Elring is listed as OE it's probably the same that it was on it. Unfortunately I don't think you can find like a much better gasket. I also got it when I did mine ~ year a go and seems good at first glance, still have a bit of pooling on the interior of the cover but I believe it's a hairline crack I need to hunt down from the plastic cover, should've just changed the valve cover back then but I didn't want to pay the 500$ for Genuine, but since then FCP started carrying a OEM Elring cover at around 250$ which I will probably try if I can't track down reason of my leak. I don't like the aluminum one as I've ironically wseen posts on Facebook groups where the alu cracked at the corners... then again it was a VTT prodcut.
