Mandatory service bulletin 632 was issued July 17th and its a whopper! The factory supplied undersized small end rod bushings from Nov 2015 to Nov 2016. This includes factory engines and rods as well as rebuild shops who used these bushings. Mandatory tear down ( top end only ) is required to do a pull test on the bushings with a factory designed tool that is not available in sufficient quantities to help the vast majority of affected parties. Time to comply 10 hrs ! Ohh Boy Katie bar the doors.
