Had all the manifold cleaner been clean out of the intake manifold? If the cleaner running down into the intakes that could well be your problem, burning the cleaner would be likely to create smoke.

When i did the intake gaskets on mine, I cleaned the top of the intakes and small amount of cleaner got into the intakes and it ran very rough for a little while until the cleaner burned off.
An e39 is like a beautiful wife, needs constant attention, lots of money, lets you down at the worse times but you’d never be without it.
