be damaged by low oil pressure after a timing belt snaps in the time it takes to coast to a stop at 70mph?

i ask because i snapped one yesterday, the first ever and after towing it home and reinstalling a new belt i hear an odd lower end sound very faintly and very sporadically an only for a second and its gone.

it almost sounds like a wrist pin not a rod and surely not a main.

oil light goes out within a second or two upon startup and has not come on at idle or at speed. have not yet put on a mechanical gauge.
