I just got back from the shop. I checked the dipstick for motor oil, and there was barely enough oil there to check. Obviously the "oily black smoke" was...well, oil. The oil had a gassy smell to it...not good. I saw no evidence of water/coolant in it.
Oddly, upon checking the codes I found a P1383. That wasn't there before. What now? :(
