上麵說:
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.
它說的是往裏麵滲,我這車是透著rubber gasket往外滲。嘿嘿。
