if you want to try,
get under the car,
clean off the hole as best you can.
(use some brake cleaner, some abrasive (file, scratchy pad....) to rough up the hole and surrounding surface, flush with more brake cleaner or alchohol)
then use some epoxy suitable for the job. (one of the JB weld or similar products)
might want to replace, or at least take a look at the filter (have to pull the battery to get to it)
then fill with proper fluid, to proper level.
you might get lucky.
just give up quick if something whines when you go to start it.
(if you want, you could turn over the engine by hand (see one of the timing belt DIYs) to make sure it moves ok.)
probably cost you $150 by the time you are done with the experiment.
more if you also need jack stands and tools.
