Is valve cover gasket required every time?
Every time I've had my valve cover off, I've replaced the gasket with the OEM BMW valve cover gasket. However, when I was researching the VANOS, Raj at Beisan said in the documentation that the OEM valve cover gasket is made of Viton, and therefore, it was not necessary to replace it:

What do you guys think? Eliminate the risk of leakage and replace with OEM gasket, or is it stupid to waste $62 on a perfectly fine Viton gasket with only 10K miles on it? Salty

Same here, assuming it's of recent vintage. Grommets, as well.
I had a go around with valve timing after getting INPA and finding that the "mechanic" that replaced my Vanos bolts did a shoddy job of the valve timing. Took me 3 tries to get the timing correct, on a 6 month old valve cover gasket. No leaks. Just make sure you carefully remove the cover leaving the gasket flat on the head. Gotta wonder why 2 out of, what, 13? grommets are Buna.
