Flywheel Sheered 6" from crackshaft in perfect circle.
Flywheel cracked and caused cracked block and transmission bell housing.
I was wondering if anybody else has had this problem and what the cause was.
The transmission was replaced before buying the vehicle as told to me by the dealer.
The first problem occurred after being driven approx 500 miles. The second problem occured after being driven approx 500-1000mi.
When flywheel cracked the second time it wobbled and broke off about a 6" piece off the top of the bell housing and 3" piece of the engine block.
On the Oldsmobile Aurora the flywheel bolts are torque to yield (stretch bolts). If I had to guess I would say that they reused the bolts. These ate one time use only and if reused would come loose therefore causing the flywheel to crack. Hope this helps!
Gary.
