Recently I had a problem of blue smoke after deceleration and I located the problem on cylinder # 2 because of the appearance of the spark plug, so I replaced the valve stem seals but the problem persists on the same cylinder. No smoke on startup, only after decel when i press the throttle, and sometimes in traffic. I did a compression test and cylinders 1-3-4 have 215 psi, and # 2 I get 225 psi. Engine is completely rebuilt with oem parts and now has 1,500 miles, and took half a quart of oil. Does anyone have any idea what I can do to fix it?

Thanks.
