Hmmmm ! very strange MM !
Very unusual. Exhaust or inlet?
Could have had a sticky valve. my guess is it happened at start up & not the last time you drove.
Possibly a slightly bent push rod.
Your tower studs are not original. Are they tight? If you have cooked a head & its gone soft, the tower studs often strip the thread in the head under the force of opening valves.
What are your lifters like? That one may have blocked or stuck at max length when it cooled & jumped the push rod out when cranked.
