it was driven with low oil for no more than five min. we stopped, added 6 quarts, then drove home.

it was smoking a bit more after the incident, but it was at high RPMs, and was in correspondence with the whining turbo,so i assume it was a symptom of the turbo bearing being worn out, and it wasn't getting enough air.

now it has very little smoke (when it manages to run long enough), and it's white smoke.

it seems like there is air in the injector pump. is there any other way to get it out other than bleeding at the injectors?
