Wow, you guys are fast. My earlier search on the subject as a DIY revealed that you had to put compressed air in the cylinders? That was enough to make me look to a shop. Perhaps I misunderstood and that is only necessary to replace the valve stem guides (that one is beyond my level of expertise.)
I'll re-search the "valve stem seal" posts again but if all I need is the proper valve spring compressor, I'm game. I'm in Wilmington, NC which is in SE NC about 60 miles from the SC border. Raleigh is 120 miles away and Charlotte is 180. No good shop recommendaiotns near here that I can find under the "Good M-B Shops" forum.
Thanks, guys; always appreciate your vast collective knowledge. y
