Dunno. I was out on the highway with the wife and all of a sudden it started to loose power. Coolant temps were fine right before that... around 190. Once I stopped her i noticed oil coming out of the main seal, fuel pressure was really high and smoke from the catch can so I'm pretty sure a bearing went...
High fuel pressure is really puzzling. I assume the regulator uses MAP as reference? Assuming the regulator didn't fail outright, it means MAP shot upward - somehow - so a lot more fuel would be injected into the engine, making it run poorly. If you were cruising when it happened (drawing a vacuum in the intake) and the regulator hose came off, MAP would increase, fuel would increase, and it would run bad.
You don't need to the bearings analyzed to know if they caused the problem - if they did they'd be blue from oil starvation. How about posting up pictures.
Sounds like the engine's already torn-down(!) but a compression test would have been very helpful.
FWIW, my catch can vent always smokes a little, so that doesn't seem like a problem assuming it's not a *lot* of smoke.
You know, based upon what you've found so far, there's a chance that there's nothing wrong with the engine.
