When you are saying "packed too tight" are you speaking about how I pressed it in place in the cap, the pressure on the seal once the cap was torqued down or both?

I'm having a hard time wrapping my head around how packing the seal into place in the cap and block would cause more pre-load, but I can see how the cap torque (140 ft/lbs w/ studs) could bungle things. The only thing I can think of is maybe I didn't cut the seal down far enough with the spacer and/or press the ends down flush enough. Maybe when the cap was torqued it put a little too much load on the seal which caused it to eventually eat itself. Still odd that it failed after a few hundred miles and not immediately. The dissection will tell the tale.
