Second cylinder threw the rod, and the roller rockers seem to be missing. Digging further I found the valves bent open. Then I found the number 2 piston rings peeking from the top? Could this have been the grinding sound I heard? I thought it was a spinnibg bearing, but maybe this was it. As you guys can see, the piston is destroyed from the bottom. I still need to pull apart the block, but here is what could have happened:

—My car wasn’t apart of the spring recall, but say something happened and the rockers were thrown, I feel like the spring would have closed the valves, and the rocker would ping-pong around the head, but it wouldn’t cause a problem.

—I drive aggressive, but the car wasn’t being driven too aggressive with the gas, more with the cornering. It had only been running for five to ten minutes from my garage that was around 55-65 degrees is a best guess, as I was heading to work. I wasn’t driving it long enough for ring expansion to happen from heat. Maybe it is possible there was some type of detonation event that cause the ring to overheat and pop out, which is why I heard a pop/bang and then grinding. Then the piston got stuck and the rod ripped itself from the piston, which caused it to spin freely, ripping through the motor and breaking.

—The other possibility is the rod snapped, and when the piston came down, it was struck by the rod, which broke the piston and caused it to impact the valves and twist in the sleeve, causing the rings to grind before the rod sent itself through the block.

Maybe the block will reveal more.

Do you have an oil pressure gauge? The rocker failure happens from oiling issues or over revs. Id question the oiling since you have gasket maker on the camshaft but having a piston fly into the valves when you broke a rod would also do it. Which reminds me i need to buy my oil pressure gauge for my new engine
