Blown up EJ20K

While reading another thread on a damaged EJ207, I figured I'd post a picture of my own damaged motor from a while back (last december)!

My blown up EJ20K :

Good job!

My thoughts are always if your going to break something, do it well.

Thats one hell of a job

Well, what I originally thought to be a cam clearance issue (which I thought I fixed by adjusting the clearance) turned out to be a bent valve that wasn't sitting properly...

The motor broke an exhaust valve while cruising at high speed on the highway... which subsequently broke the other valves and ate their way through the piston... I found 1 valve head in the oil pan!

I rebuilt the motor on a new EJ22T shortblock, and took out the holed piston and keep it as a souvenir!

Here's a picture of the cylinder head, notice how the hollow valve stems are still in there:
