上面说：
In gasoline engines:
A puff of white smoke out the tail pipe in the morning is a sure sign of worn valve seals allowing oil to seep past the valves into the combustion chamber when the engine is not running.
This is a sign of a high mileage engine. Allow a few days for LUCAS ENGINE OIL STOP LEAK to correct this problem. To keep this problem corrected a quart will probably have to be added with each of change.
它说的是往里面渗，我这车是透着rubber gasket往外渗。嘿嘿。
