The most common cause is worn valve guides. Any oil sitting on top of the valve will run down the valve stem while the car is not running. When you start the car, the oil that has accumulated at the valve seat immediately gets sucked into engine and burned off when the engine starts. This results in the blue puff of smoke coming out of your tail pipe which goes away after the motor has been running a while. Carl King http://www.classiccarauto.com
