Doc,

You don't say whether this was a new chain, old chain, new timing set , single or double roller??

Old chain could be streched which would lead to failure

New chain on old gears could fail due to worn teeth on the gears

Installing a new set or any changes in the timing set could result in mis-alignment of the chain and or gears which could result in failure.

Double roller more resistent to stretching than a single and worth the few extra $$ as insurance

Also poor lubrication to the timing chain can result in failure.

Also as Carnut mentioned you should check the valve train for damage and to insure that it's not dragging and causing the chain/gear to fail.

good luck,
Mike
