I helped pop 15 of BigT's yesterday while visiting with Bill Heath after a run down to NV to help recover a DMax. Long story, different thread.

Injectors. As far as I can remember from campfire stories, these came from the years when Bosch Germany was forced to have a come to Jesus meeting with Bosch India over a mass purchaser’s discovery of a 40% fail rate prior to use (pop pressure consistency, spray patterns, chatter quality) so I was a hot mess from these. Fortunately, not the case.
First off, I apologized profusely to BigT as I didn’t count the number of injectors in the box and didn’t realize there wasn’t 16 in it. I thought I’d misplaced one but, that area of the shop was relatively organized and after much searching…I didn't find the 16th one laying around nor, an empty box. I'm really hoping he has the one AWOL injector hiding in the garage.
Results, IIRC (they are boxed up in the back of the car right now), 9 popped at 2000, 5 popped at 1950psi and one at 1900. All but one had very good spray patterns and good chatter. A few chattered a little better than the others but, there’s always a few brown nosers in every group trying to stand out. The one with bad spray (streaming vs misting only) and no chatter still popped high (2000?) but, pissed at first.

And then it opened up and sprayed in streams.

The pissing was probably my building pressure up before a full pull on the tester.
A good deal of time was spent trying to get another nozzle and pintle combo to work in this injector body but, even when we found a set that worked in its original body, it wouldn’t perform in the new body which is, beyond scientific exploration, worth. Unfortunately, with only used injectors to rummage through for a better functioning nozzle and pintle, we couldn't correct the problem.
As BigT said, one injector body had a plethora of rust on the threads and what seemed like thread damage (looked crushed in a few spots on initial inspection). The box for it, like all the others, looked like it might have gotten damp at some point but, the paper all the sealed in plastic injectors were wrapped in was dry, showed no signs of any moisture and the plastic wrapper the rusty injector was in was undamaged with no signs of impacts, holes etc. But, as you can see, a good wire brush cleaned things up which surprised me as it looked like it would take some filing or maybe running it through a die(?) to clean up the threads.
In my opinion and I’ll quasi quote Bill, for the price payed, Hell of deal. Now to find injector 16….
