My mate had an unfortunate weekend.
400whp S14 SR20VET 20V with a built bottom end. He thought he heard rod knock so he shut it down.
Cylinder #4 doesn't look good..

Next step, remove head

Cylinder liner

Valves

Seems like a mechanical failure, all the other cylinders look perfect. No knock was ever registered. Headgasket is still intact too!
