Bob that was the 4th time I have had the flywheel break all 4 bolts. The
first time was 4 or 5 years ago. Broke all 4 bolts a 1 pin, replaced bolts
& pin 2 races later crank broke just behine #6 rod!! Replaced crank!! Next
crank I put 4 pins & new stock bolts,safety wired them. Same failure. Next
redid rear of crank,4 pins& new ARP bolts ,red locktite. That,s the one
that let loose a BRIC.
Best we can tell that type of 6cyl. crank is real bad about harmonics,
can,t take high RPM,s.
Never had one come out of bellhousing..
