Last session of the day the #2 cyl liner spigot broke apart ruining engine...never had this happen before. Just a few days ago I completed full engine repair. It is tight and strong. Dec 1&2 at Homestead in Miami is CCS grand finale with vintage classes. I'll be there!

what is a cyl liner spigot ?? what kind of damage did it do ?

liner/sleeve same deal.
a snap ring can come loose.
metal can just fatigue and crack.
overheating can cause the piston to swell enough to grab inside the sleeve and tear material from the piston and friction weld it to the sleeve,until it builds up enough and locks the ring ends together and pulls the top off the piston.then it starts rocking around in there and beating the sleeve/liner until it brakes it.
