What a day! After calling a local Mercedes dealership to see what their guys were using for a plug socket, and going from parts store to parts store looking for a thinwall, I discovered I already had one in my toolbox. It slipped right over the first plug I tried to pull. Man, are they ever tight. It scares me a little because I've broken a plug in a dodge pickup I had once had. I've gotten four boots loose, but I'm still fighting the ones toward the back of the motor. When you remove the coil packs from the cam covers, do you unplug the HT leads at the coil pack, first? Also, do you know the (ft/lb) torque setting on the plugs? I got the anti-seize and the di-electric grease ready to go for the re-install. Now, all I need is the time. Thanks for all the help, so far.
