I recently built an engine for a fella. He rebuilt his injectors himself to put in the engine once I was done. More than half of them hung open on first start and flooded the turbo/exhaust with diesel. The truck started and ran, but diesel was pouring out the exhaust at a pretty good rate. He swears he followed the instructions/video in the kit to the "T". Needless to say, he had to buy new to get his truck moving out of the shop it was sitting in ASAP. No time to try again on rebuilding them or figure out where he went wrong.

Thanks for the encouragement. I will be sending them in to be tested. I received a helpful response from bitterroot that if they're going to be stored for any length of time to be sure to fill them with calibration fluid. I will be immediately sending them in to be bench tested, and once complete they do fill them with fluid prior to returning them so they'll be stored properly.

I didn’t realize Bitterroot was still in the injector game until I saw your post. I thought they moved to other machining projects for the time being.
did you read their own description? Their kit is not a substitute for a truly rebuilt injector. @knottyrope was not questioning your machining skills. For injectors, it is a matter of tooling that makes it difficult to DIY an injector. After you buy all the tools, you are behind the curve for cost benefit.
despite what your mechanic says, does the truck run well? If so, don’t sweat it and roll on. If you get to the point the truck actually needs injectors, send them to Rosewood and be done with it. If you want to do something, make a break out box to test the injectors. Don’t waste time rebuilding them

They’re not really. From other people I know that sent ones there for testing recently, they basically condemned them and sent flow sheets that do not show flow data like any other 7.3 injector builder, and then told the customer they don’t repair them. So that customer had to send them elsewhere for re-testing and repair, in essence a complete waste of money for the testing BDP did…
