Oops, thank you for pointing out my fumble-fingers. Corrected.

I stand by my count. Most of these vehicles were of the "Well, it's a Mercedes, they run for a gadzillion miles without any maintenance" type of owners. Not all of them were OM617's. There were a few OM615's and OM616's in the mix.

I suppose my location could add to the number of these incidents I have seen. Drivers are less likely to stop when the next available place is 50 miles away in 115 F temperature. Probably 90% of the heads I replaced were in the era before cell phones were common.
