Having had only 914Turbo + current 912S in EAB, IMO, too short duration for lt. resultant damage. However, as admirably stated to avoid apprehension, either call LEAF, ask for Brian + or other in back shop line, younger Rotax gurus - or Ronne (Smith) LSA of So Miss., (Lucedale), gray haired Rotax guru flies one himself + hosts fly-in. Ask for him, over Son Morris, again, on the shop back line. They may ask you for engine S/N, Ronnie will. BTW, isolated incident, no known SB to address this I've known of.
