Our counter balance shaft failed last August. I'm sure many of us remain interested in knowing what caused these failures. I thought it could be useful (especially for new members of the "V8 CB-Club") to have a thread with information from other owners whose V8's have failed. Engine # 6833 is reportedly the cut-off for problems. This might help identify (or exclude) particular circumstances leading to the failure of these bearings.
I'll kick off and would encourage anyone with ideas for additional categories of information to chime in. Maybe one of the administrators could consider making this a sticky, although sadly I suspect it will be bumped frequently enough that this may be unnecessary. We can always edit our own posts to add extra info as the thread progresses. I've suggested a format below, with "na" for 'not applicable', and "?" for 'unknown'. Please make suggestions. Sorry for the survey-like nature of the post, but such a resource may be of use for those other unfortunate souls that experience this sort of event.
