Roush blamed himself for the pistons saying he tuned for mileage. He also said they were going to run more piston to wall clearance and enrichen the mixture. I read this stuff on Roush's website so who knows if the public gets the real story.

I suspect the pistons got too hot and tightened up in the bores.

A few years back everyone went to direct feed pin oiling to help with the piston pin problems.

Speaking of light weight, has anyone seen a piston-guided rod set up?
