This sounds exactly like the runaway on my '85 TD a few years ago, except it started
at around 3500 rpm. In my case, the problem was a clogged airfilter, combined with
two much oil - I had quickly added an extra quart before leaving on a trip, without
waiting for it to drain down. Even after the smokescreen, I was still 1/2" above max
on the dipstick. The intake plumbing was full of oil - a clogged air filter causes the
turbo to vacuum oil from the valve cover. I suppose another problem could be seals
on the turbo, but I've never seen that yet on mine.
