3.0L engines may develop an excessive oil consumption issue. Blue oil smoke may be noted from the exhaust during deceleration conditions (high engine vacuum). Our technicians tell us that this condition can be caused by valve guides dropping out of position. Updated valve guides with a revised snap ring grove are available to correct this issue.Google+

I also suffer from blue exhaust smoke when I start my 91 Lebaron, but it generally abates after a few mintues of driving the car. At first I attributed this condition to piston ring failure, but as it clears up once you drive the vehicle, it has to be the value guides dropping when the car is turned off, allowing excessive motor oil to collect around the valves which has to then burn off when you start the engine each time. I have not as yet fixed the problem, just learned of it in past few weeks.
