okay talked to the mechanic that worked on it, he said i had a bent/cracking rod. possible a casting flaw. believe it or not, at 70,000 miles the dealership is actually going to try and go to bat for me, so some ford field engineer is coming in on tuesday of next week to take a peek at her. hey even if they kick in half or whatever i guess that is good....even though i wanted to do a 3.0 conversion. he also said this was a stress thing no sign of oil starvation and no damage to the top end...which is good because i can't imagine getting a head job to these things is a cheap date,
