It is usually fairly obvious if the problem is valve seals. The engine will smoke some after idling at a stoplight. The rest of the blue smoke is piston/ring related. There is a possibilty of a stuck ring if it has been sitting but not on all cylinders. You would probably have to tear it down to correct the problem.
