What is the purpose of placing a piece of silk thread along with
sealant when joining the two cast halves of an aircraft engine. Is
this done on all engines or just Continental and Lycoming, what about
4-stroke Rotax.

During the war Rolls Royce used to machine to close enough tolerances that they could use a piece of silk alone as the seal between parts

The silk thread IS the seal even today. The so-called sealant is there just to hold the silk thread in place. Otherwise oil could work its way past the ordinary sealant.

Some useless trivia.
I read a book on Rolls Royce once and it said that there were three 1909 silver ghosts that were refitted with armoured car bodies and sent into action in WW I. One of the cars had problems with the extra weight and had to have the front spindles replaced. After the war the original bodies were returned to the cars... Then in WW II the same cars were refitted with armoured bodies and saw service in England. At the writing of the book all three cars were still on the road. Not bad considering they were made over a hundred years ago and there were less than ten made.
