Thanks for the responses! I couldn't be sure if it was fuel smoke or oil smoke. Kind of bluish dark grayish. It smells at the tailpipe like it is running rich but that is when it is not smoking.

I have been told it's sticky valves/loose valves/catalytic converter. Nobody knows. I can't see it being valves since it has never done this before and was so extreme when it did happen, but I'm no mechanic. Just seems to me like that would be a gradually worsening thing. Tomorrow I intend to get out there and check into it further.The first thing I will do is get that broken PCV out. Then check oil level. Then bang around on the cat converter and see what I get. Will definitely post back here, and continue to watch this thread for more advice.
