E85 Can Mess Up Your Engine!

The rings were so stuck they broke the ring lands between the oil ring and the #2 compression ring and the #2 ring and the #1 ring. You can see the cracks here.  Normally detonation causes the top ring land to fail first but those were all fine! The oil ring drain holes are all filled up with baked goo as well.

This piston had a chunk missing out of the ring land. The stuck rings would not move as the piston moved up and down and this put a huge stress on the ring lands.

With all that mess going on, you would think the cylinder walls would be messed up but no, they were like brand new with the exception of some goo around the top of the cylinder above the #1 ring.
