Very common item to go. I would not drive it. Have it flat bedded to your mechanic of choice unless you want to diy. Lots of previous discussions here on the forum regarding this subject.

I concur... sounds like the A/O failed or at least partially failed/cracked. I've seen one fail at the track and there was a LOT of smoke. But if you have smoke AND oil on the O2 sensors, then you're either looking at a failed A/O separator or something much worse inside the engine. I'd lean towards the A/O separator being the problem and get it replaced. Do a search as there is an option to upgrade it to a better unit.
