My questions are:
Is it possible I damaged injectors in both banks that quick?

Or got 2+ defective injectors from the factory?

Or do I have a head issue?

on a Cm570, 870, or 871, always adjust the overhead valves + set the proper torque on the injectors before doing an injector leak test to prevent false positives.

I re ran the overhead and everything was within tolerances. Re ran the leak test and still getting bubbles. #1 & 2 on the front bank. Haven’t switched to the rear bank again but will in a bit, had to run in town and take care of some things quick. I’m assuming I’ll get bubbles there as well. So back to square one as to why I have 3+ injectors bad in under 9 months?
