1994 Honda Civic

Oil in air cleaner, air intake hoses, foamy oil.

If it was very overfilled then you may find blue smoke blowing out of your exhaust.

If not corrected seals may be damaged.

If it was driven reasonably for about 100 miles nothing will be done. Hard to guess as it is hard to tell how overfull it was, and what condition the oil was in. If it was extremely foamy it wouldnt take long.

I have seen hondas run a few hundred miles with no oil in them so they do hold up pretty good with lack of oiling.

If vehicle is turboed then there may be some damage done to the turbo due to overheating from lack of oil and dirt gettign on the impellers causing wear. But if you notice no damage done to vehicle as of now I wouldnt worry too much about it
