Hi there, was out driving my car today and put the pedal into it and it backfired on boost, now my problem is its got a solid knock under the engine, i put a stethoscope up to the sump and i can here it knocking against the sump on either cylinder 5 or 6. I put it down to a big end bearing has s@#t itself as its there all the time and obviously from the heavy knock, just seeing what you guys think?, and if im on the right track. Regardless its time for the sump to come off :| .
Also does anyone know where i could get some big end bearings from preferably hardened and would anyone have a rough idea how much they would set be back.

Cheers.
