Anyway, how would I diagnose if an injector is "leaking"? Can I do it with a stethescope or something?
I plan to send my injectors to CSW to clean and pop test, likely install new nozzles too. Is there a way I can diagnose which injectors may have issues before sending them out?
Id rather get my current ones rebuilt unless there is really good reason against it. I'd probably ultimately do my 240D as well, but at 74k, I assume nozzles, if anything besides cleaning and pop testing would suffice. the 240d does run rough ifg I back the idle all the way down...
Thoughts?
Thanks!

Hi
I'm not clear what your indy means by injector "leaking" If you don't see any fuel on the outside or bubbles where it screws into the head - maybe he thinks the nozzle isn't shutting off correctly and fuel is dribbling into the prechamber. Seems like you would have a miss or some black smoke were that the case. Pop testing would tell if your injectors have a good spray pattern and are popping at the correct pressure. You can make a quick check of injectors by cracking the hard lines at the injector - one -by-one, with the engine at idle, to see if one cylinder reacts differently from the others.
Starting failure sounds more like a glow problem - or perhaps a compression problem. Both not hard to check as a DIY - see threads.
Good Luck,
