@v8volvo I had bought the engine with 270k km on it. It was running ok but a compression test revealed all cylinders were below the recommended wear limit, so I decided to rebuild it. One thing after another I ended up getting all new components, although some of the old ones (like the pump) didn't show any obvious problem.
Today temperatures were less hellish and I managed to spend the afternoon in the garage. To my disbelief, one of the two "new" injectors I got in the mail is junk. The second one also leaks slightly when held just below opening pressure (see below). At this point I will just return all of them and move on to a different shop, I don't trust this one anymore and it might very well be that the overfueling issues I'm seeing come from one or more injectors.
While I patiently wait for a new batch of injectors, here's a video of the "leaky" injector (the second one I mentioned above):

Sorry if the video is shaky, I only have two hands
. In the video, I'm holding the pressure tester at just below opening pressure. As you can see towards the end, a drop of diesel forms underneath the nozzle although opening pressure is never reached. Just so I have a good reference point when the new injectors will come: is this considered "ok" or even normal? Or would you say that injector too is bad?
