There are defect cases that will cause it too. Sometimes in large numbers,
like the modular ford DOHC V motors. Large numbers of problems. But I think
you're right, usually it's under torquing that does it otherwise. I
understand it can also happen on AL heads if sparkplugs were ever removed
hot and caused damage to the threads without actually stripping them.
