Check the coolant and oil, see if they look like its mixed and if you can try doing a compression test.

If it is oil one thing you can do is replace it with a full synthetic. It's an old used car trick. Full synthetic oil won't smoke on it's own. This won't solve your problem but will eliminate one possibility.
