Usually its the ???....... Bolts coming loose on a properly balanced engine ,and I'd have no reason to doubt Wilkes is'nt, usually results from a cracked crankshaft.,or a torque converter problem..............The LS1 has a rather long flywheel bolt ,due to the fact that most flywheel setups for adapting to a conventional converter/metric 200 trans,use a spacer between the crank flange and the flexplate, so it could be more suceptable to vibration loosening it. ..... ....I've never had to use anything other than medium strength Loctite to retain the bolts on an LS1..............Engine vibrations can cause strange things to happen to seemingly unrelated components. ......I recently had to remove a harmonic damper on a BBC that had welded itself to the crank snout due to a vibration caused by an out of balance torque converter!. ..........Tom
