Try a dose of Auto-RX, follow instructions. If you are still getting smoke in the morning and on slow down from a run on the freeway but it still runs good you might want to replace the valve seals. They can be replaced without removing the head. It's a common cure for old Civic's. Do not go thicker than 20w-50 and add nothing to the oil, no honey, no STP, no fix-it-in-a-bottle, nothing. I put myself through college buying smokers and fixing them, except I did not have something like Auto-RX. I used hugh doses of Marvel Mystry Oil and did valve seals in my garage. It just takes an air compressor and a few tools, but if it's not what you do find an independent mechanic that knows your brand of car.
