you say timing jumped 3 teeth in that VW engine?

well you better be checking the valves in the head then
those engines had almost zero tolerance in the head and valve train and if the timing got off any at all there was valve damage pretty much 100% of the time.

if and i mean IF that engine is running well it wont be for long
we've done too many of these in our shop to know better than to assume everything is ok inside it after something like that
