Asked by jmeech Oct 05, 2016 at 06:20 PM about the 2007 Jeep Grand Cherokee Overland 4WD

Question type: General

I am trying to figure out what caused the damage to this piston and head. I
also found little pieces of metal in the intake plenum. not sure what they are
either? Valves, rockers, springs, rods all look okay.

the plug gap is not closed. It was driven every day. The only knocking was when it died.

it is a valve seat, probably got the engine too hot and as it expanded the seat dropped and got broken up. That is what happened to mine.
