interested in what happend about re and re the freeze plug. My plug just
below the intake manifold has also rusted through ('89 300e) and I need to replace it. wondering if it is screw-in or pressfit? Mind you, can't see it being a screw-in type since it doesn't appear to be configured for - pardon me - 'screwing'. That is, it's just a round blank with no way of applying a tool of some kind

cheers, guenter
