The Grommets arrived today, a day earlier than expected. I am a little embarassed about the grommets situation. I was under the impression that the grommets have rubber/metal combo when, in fact, the grommets are all rubber and the metal top part head is part of the overall metal bolt sleeve. I guessed that grommet were so closely tight with the top head that I thought it was all one part like rubber/metal combo grommets. In addition, when removing the old grommet from the bolt sleeve, it was loose and not tight like the new grommets. I apologize for the confusion in that regard. Live and learn.

Now I have all the parts available to me for the valve cover gasket situation. I can't wait to get to work on the Mercedes. I will follow up on the issue as soon as I complete the job.Stay tuned.
