A bit of clarity on the injector unit and how to change the oil. The plaque has instructions - I hope this clarifies what you need to do. It will sound better ...mine all did after I did this @cherryle8 for other videos.
Footnote: Be sure to put it back on in exactly the same position ( there is a mark on the housing ). It's place can advance or retard the injection timing. With the diesel it's best to run for a day or so before making a final decision.
