We want to help you get your diesel performing better. If you own more than one older Mercedes diesel here is you chance to purchase 10 nozzles for a fantastic price. If your injector tips are worn out here are my recommended replacements. These injector tips are made by Monark in Germany and they are designed with a finer mist pattern than that produced by the Bosch tips. My experience has shown that these tips work better (fuel burn) especially on higher mileage diesels with less than perfect compression numbers. On my own diesels I have also noticed less injector nailing (pinging noise) with these tips installed.
Installation notes: Applicable for all 4 and 5 cylinder diesel engines 1968 to 1985. No instructions are included with this kit. If you need instructions I would strongly recommend you purchase my new manual Diesel Injector Cleaning and Testing Procedures. It covers in detail how to remove your fuel injectors, install these new nozzles in the body holder, and test them for sealing, pressure, and proper spray pattern. CLICK HERE to order this manual
Ideally you should pressure test and set the correct release pressure when installing new tips. If there is a Bosch repair facility near by you can have them do this testing/adjusting for you. You can install these tips without checking adjustment and in many cases they will fall into an acceptable pressure/spray pattern range. This might be preferable to badly worn out fuel injectors - but best to test pressures to know for sure.
NOTE: If you are running SVO WVO or B100 these have the highly touted DN OSD 261 specification. Many, including myself, have reported great results with these nozzles when running heavier viscosity fuel.
I recommend you have a torque wrench handy when rebuilding your injectors. If not we offer one at a great price. CLICK HERE to order.
