I would recomend using a geotze brand head gasket and not an elring. over the last 15 years I've never had one fail under normal use.I've done many 103 gaskets for a second and even a third time. always elring. I know this is what the dealership uses but,it doesn't mean it's the best part.All the mb dealer techs I know won't use them on their own cars. just my h.o....Paul
