We have heard of this scenario a few times and discussed it HERE.

 

Apparently under the right conditions, enough antifreeze in the oil can take out an entire set of injectors. If you didn't change the oil during the repair, you should have. The one factor we cannot control is the customer or the driver of the vehicle and how long the engine has been run with coolant in the oil. Usually this is not the case as when a cooler fails it becomes evident very quickly.

 

And to answer your question, I personally have not seen this.

I have seen it 6 times now. Always when customer "limps" (read as: drives till it wont go anymore) it in rather than get it towed.
