Agree on the genuine OE BMW gaskets AND grommets. All others will leak sooner.
FYI - Aluminum valve covers won't help you. My S54 on the Z4M has an aluminum valve cover and it still seeps/leaks after some times, but genuine OE BMW gaskets AND grommets last the longest of them all. I've tried elrings, victor reinz gaskets and don't have good luck with them.
