Blew $400 on a reman injector that failed in 2 months

Picked up a reman injector from a place I'd never used before, figured I'd save $200 over OEM. Installed it in a '07 Cummins 5.9, truck ran rough for about 8 weeks before it started knocking. Pulled it and found the spray pattern was way off, basically trashed the cylinder. That $400 injector cost me another $1200 in labor and parts to fix the damage. Anyone else had bad luck with cheap reman parts on common rail engines?

Whoa, hold on, that's brutal! I gotta say though, did you check the fuel pressure before you slapped that injector in? A lot of guys skip that step, but a weak CP3 pump can kill a brand new injector real fast because the spray pattern goes all wonky when it can't hit the right pressure. If your pump was already on the way out, it would've trashed that reman part no matter how much you paid for it. It's worth testing before you throw more money at the problem, since a failing pump can murder a whole set of injectors in no time.

Yeah @patricia_rodriguez that's fair. Guess I learned the hard way, like I do everything.
