If there was too much piston to wall clearance, it would rock around and finally break, or possibly overheated and again, rocked around. Was the engine noisey before it broke?

Nope... Broke As soon as I came to a stop at first set of lights off the Highway (300-400Km trip)
No Noise before. No Overheating on the highway.

Commpressions Fine...Turns Out I have a 2.5L block But was running a 2.2 computer (Shocked when I pulled the pan to find out that one)
I don't have the Piston out yet, or head pulled, but you can see the broken skirt in these pics

Well the block doesn't matter, its whats inside, same block. But if your running a 2.5 engine on a 2.2L computer then no wonder you broke something. If I remember, the 2.2's spark curve is more aggressive and its leaner.

I fully agree...I bought it this way..Thus the shock of it being a 2.5 (was told it was a 2.2 and had no reson to think it wasn't (A555, equal lenght axels, 2.2 computer etc etc.)).
But I'm suprised I just lost a piston skirt..Thus wondering if this was the cause or not.

Probably and not to mention, looks pretty gummy in there, a wrist pin could have locked up.

Thats a pretty clean engine. I'd be willing to go after 1 of 2 things- 1) You had a wrist pin catch in the rod, causing the piston to slap the cylinder wall. This could be caused by a few things, most likely either someone tried to rebuild that engine and it gave way, or oil starvation. Usually oil problems will take out rods first... Also, detonation can cause damage to the wrist pin as well.

2) Overrevved engine. It may not have done the damage right away, but if it was overrevved, it could have damaged it and it finally let go.
