I'm wondering if the oil cap failure was a symptom and not the actual cause. Just thinking theoretically here, if the PCV became completely clogged, crank case pressure from blowby gasses will seek an alternate route to exit the engine and find the weakest point.

Regardless, given the spotty reliability history of the 2.3 liter engine, there is no way I'd put another one in. Said another way, 2.5 Duratec all the way.
