but no, i actually did not pop test them, 1.) being i didn't want to buy all the stuff just to do it once and 2.) no one in my area even wanted to TOUCH the injectors. all shops local to me like to say "everybody stopped wrenching on those cars ten years ago, give it up" to hell with them
im pulling the valve cover again today to check everything out.
my primer pump actually always leaks, and when i begin to pump it, it really starts pouring fuel out. This isn't normal i suppose?
Sorry for my lack of knowledge on this car. I've never owned/worked on a diesel, much less a mercedes diesel. I'm only 21 so i have never been around these cars. my interest for them sparks from my dad owning them back when they were new, and it's just such a cool car to me.
so i'd love to get it back in good reliable shape. i have hope in this engine since the noise is intermittent.

Two items:
1. Since you bought the injectors from **************, you should be able to call them and discuss whether they pop-tested them. Discuss your issues with them as well.
2. Have you replaced all the neoprene hoses which are connected to the fuel system? I once found a problem with my nephew's car, where the rubber hose at the tank was buggered. The correct fitting had been replaced with a plumbing fitting and a piece of hose. This hose cracked and periodically sucked air. Everything up front looked perfect and I went crazy looking for the problem. Found it accidentally and lear5ned to look at the whole system when I diagnosed things, not just the commonest items. So check your fuel tank area too, lol.
Good luck!
