Take the brake booster line, where and put it into the bottle with the engine running. The seafoam will run through the line and into the engine where it sits and eats away at the carbon deposits. When you start it back up all the carbon and remaining seafoam is burned off. Good idea to change the oil to get rid of any seafoam that seeped past the rings and into the pan.

Like I said. When using ANY type of engine flush that is added through the oil you should NOT drive the vehicle/put load on the engine. Just let it idle for 15 to 20 minutes. Oil should be black and run out like water.
