Please forgive the noobie C&P its my first but have lurked BITOG on and off :).
Engine was a K20A2 in my track car and the filter was run for about 4 hours before the engine let go.
Engine mode of failure was a rocker roller bearing had broken off and wedged itself into the rocker itself and jammed the valve wide open to have the piston hammer it.
K20A2 was stock with the exception of valve springs and camshafts with unknown mileage and run time(Track usage was roughly 30-40 hours)
Can post the engine failure photos if there is interest.

For some reason I don't have the spark plug photo nor the cylinder head damage.
Piston had turned into a nugget, the wrist pin was deformed and had a small crack in it.
Sleeve cracked and metal bits everywhere of course :)

Two photos extra due to the 10 photo limit, note that the previous 2-3 oil changes were run on wire backed fram ultra's but had an issue and sourced this last minute for an event. Not sure what filter to run now for the K24 that is being assembled(PG built napa gold's? not able to easily source a lot of US filters due to being in Canada but head down there occasionally)

Second photo is the engine being pulled out at a friends house about 3 months ago, block and all the assorted bits have been recycled since.
