我从Amazon已经买了这瓶了，就在手边。但是看了一下说明，好像不太对症啊

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。
