Jump-started her today to go down & get a new battery, and it was like the electrical system was having a rolling brown-out when driving; the ECU kept re-setting, the radio would turn off when I hit the brakes, as would some of the gauges etc. Basically, the battery had NO capacity left. I also got a bit worried by the amount of smoke at one point, but it seemed to be mostly oil on the outside of the exhaust, and the new turbo blanket & downpipe wrap "settling".
After replacing the battery, all those electrical gremlins were vanquished, and she was running a lot better. I still need to keep an eye on the oil consumption, and make sure there are no other leaks after stripping the engine down prior to the oil line catastrophe, but for the most part she feels pretty normal.
