That specific Elring gasket, 812.081, which replaces Mercedes #180-016-46-20, also fits the 220b(M180.940, 220Sb(M180.941), 230(M180.945), 230S(m180.947) and a few others. Elring does not provide options to this gasket for the 250S or the others. That suggest to me that there is something very particular about the oil/coolant ports and other features that become more determinative than the cylinder bore.

I just got an email response from Elring stating that they could provide me with a 812.081 gasket, made in Feb 2020, for 225 euros + 50 euros shipping. At today's rate that's about $303USD. That's for the gasket only. They did not mention the availability or price for the gasket kit (826.464). The email was not information packed. So, it did not address their meaning of "No Longer Supplied" - no longer manufactured, or production delayed, or shipping delayed, etc.

Hopefully I can get some more information about this later this week.

Thanks again.
