The copper washers are one-time-use, so yes if you remove a DV, you need a new copper washer. If you feel lucky, you could try softening them by heating with a torch until they are glowing orange, then allowing them to cool, and cleaning them off REALLY well before installing them.
Injector sudden failure: easily caused if the shop was not clean and careful and allowed some contamination into the DV or the injector line. That contamination then traveled to the injector nozzle and may be causing a blockage or holding the nozzle open so it pees a stream instead of generating a fine mist. (I'm beginning to suspect that is what is causing the miss and nailing that I've got going on with The White Whale, my 124.193 '87 wagon) ------------- Max Charleston SC On Thu, Jan 26, 2017 at 3:11 PM, Larry Turner via Mercedes < mercedes@okiebenz.com> wrote: > Max & Curley, > > I can see why you would say an Injector might be bad, and I might tend to > agree, except it ran great before the shop replaced the o-rings.
