Dave - Yes, I have first hand information on a failure. Interestingly enough, the bottle had split down the middle at the casting seam, rather than at the "crazed area" near the aft upper end of the bottle. The car (see "resurrected barn relic") apparently had a history of overheating, which lead to it's being parked in the barn. The real problem turned out to be a failed bolt on one of the water distribution pipes under the intake manifold. The bolt has been repaired. But, I had to donate my original plastic bottle to the cause to get the relic on the road. As with most D owners, I replaced mine proactively when I heard that it was a "must replace" item.
