Like the title says, I just did the Seafoam treatment to my P5. Divided the bottle in three separate doses for the car, one part for the oil, one part for the gas tank and the rest on the brake booster line. As soon as I finished pouring into the vacuum line I quickly turned the car off. Waited 15min and when I turned it back on, no smoke came out the muffler or anywhere. Can someone tell me what happened?
