Just another day in the office.
 

Anyone guess the demise of this poor Ford Focus 1.9L sohc?:facepalm:

Lack of changing oil, bad gas, overev, and no coolant?

:facepalm:

Is that detonation on the head, or parts of the piston that are making those craters the size of a teens forehead?!? O.o damn

The squish areas look like they've done a lot of squishin' - on things that don't squish...he he he

A single intake valve seat let loose and basically hammered the shit out of cyl#4, then somehow made it's way into cylinders 1 & 3 by way of either the intake manifold or the egr ports.

At least those engines are dirt fucking cheap.

Looks like a horseshoe is stamped onto those pistons haha!

If it passed through the EGR at least you know it's not clogged! :P
