Cm871 repeated same injector failure

[gearhead]

I would suspect a problem in fueling system mybe to much fuel pressure or something. I also wonder if compression is getting past the tip and destroying the injector. I would love to see the tip. Also i wonder if the top of the piston is full of carbon and raising the compression ratio up enough to mess it up ( this is very unlikely i know i laughed while i typed but thought crossed my mind so i said it there LOL).
