I used nothing as a sealant, as BMW makes no mention in TIS. Timm from the UK is an active member on the e38 forums ( meeknet.co.uk ) - and he does mention using some silicone grease, but I did not even do that ( Link here - Timms BMW Water-Coolled Alternator Replacement )

Thanks Noodlesandsam. It's so strange that the replacement gasket looks nothing like the one that came off the original part (the oring that sits in the groove). Sheck out the link above f you're curious.
