You may have multiple issues - a bad valve that's causing a loss in comression on #4, combined with worn rings from oil changes that weren't frequent enough, or possibly worn valve guides/seals. One qt per 700 miles is pretty heavy consumption and you may eventually destroy your cat with that much oil going through it but for now I suggest doing what the mechanic suggested - keep driving it. Some long highway runs may help too if it has had a lot of short trips and cold starts.
