Prevented a Broken Crank???

[TrentNell]

I did all the right moves with my build used great parts took extra time with the build to make sure everything was perfect as could be expected, we very particular with the breakins I feel I did everything right but with only 2300 miles on my new fresh engine, I broke my crank, DAMMIT. I didn't race, pull, street race, nothing this is bullshit, any advise, things to look for when I tear it down, I'm looking for answers, I was using a Fluidampr, I hope that was not the problem, the rest of my specs are in my signature, any words of wisdom would greatly be apprieciated. I believe it's my crank I pulled the damperner tonite and you could move the crank snout, maybe it's not broken that's probably wishful thinking

what were the main bearings set to for the tolerance ?

yes all the tolerances where with in range, crank was balanced in the block with the news rod, pistion, dampr,ect.

I was wondering if Super Diesel was ever going to say what he found.....

what injectors were u using??? When I orginally built my bottom end with 165,000 miles everything in the bottom looked great journals, bearing, ect . I'll let u know what I find when I tear it down if I see any strange looking bearings. maybe we can all work together and fixed this problem for all.
