i think so. i just rebuilt the whole topend and i was kinda beating on it when it happened. i was doing close to 80 and some idiot came outta the other lane and cut me off , i swerved nailed it and slung my soda out the window at his *** and around 100 the car started to slow down. i pulled over and didnt hear anything........until i went to get back on the road. anything over 2k rpm and the bottom end rattles like hell and i have no power. water and oil is fine , so i either spun a bearing or have a broken wristpin
