Then i continued to pull the rods and the main bearings out, this is were things get weird. I pull the first main, crank looks great, no grooves, just some minor scuffing. Second main looks good too, bearing had some minor grooving, but the crank looked great. Third looked really good on both bearing and crank, fourth also looked awesome and both bearing and crank. The 5th as well looked good, at this point i begin to think its the rod bearing that had a failure.
So once again i pulled all four rod caps and everything looked great, no grooves, just some minor scuffing, i had a friends dad come take a look and he said everything looks normal (btw hes like a thousand years old and has been messing around with cars for sometime now) Can anybody tell me what could possibly cause the noise i was hearing, what were those black chunks that i found in the pan?
The sound was similar to this: http://www.youtube.com/watch?v=68U-8-ry ... r_embedded

these marks aren't limited to the areas photographed, the whole girdle is covered in chew marks and cracks.
