There is a guy on German eBay that sells Monark nozzles at very competitive prices, and ships promptly. I just bought a set for the 300D and they were $137.00 shipped. I got them in about a week's time from the Fatherland.
Bosch nozzles are garbage according to a couple of fuel injection people I talked to. You can disassemble your injectors and clean or replace the nozzles, but they really need to be recalibrated if you do, especially if you replace the nozzles. Insist on having the set matched to 5.0 bar or less, as the farther apart they are as far as opening pressures will have a significant effect on the smoothness of the idle and efficiency of the engine. If you've never done this before, don't have a pop tester and an almost surgically clean work area you're heading for a very unpleasant result. -D Sent from my iPad > On Feb 6, 2017, at 2:43 PM, Curt Raymond via Mercedes <mercedes@okiebenz.com> > wrote: > > You can but I don't think you'll be happy with the results.
