Seafoaming a 2004 and 2008 Pontiac Grand Prix

Travis's Grand Prix always smokes more than mine. One thing i noticed is that every 3800 engine I've done, the smoke is minimal to nonexistent.

Odometer reading at the time of this procedure was just over 88k. On GM's 3800 s/c V6 you DO NOT suck Seafoam through the brake Boost vac hose. SF may damage the Teflon coated s/c rotors. Instead, discount the vacuum line directly beneath he s/c snout. Once you remove the tube/line you'll see a metal fitting going into the engine. Just attach another tube to it so that you can have the running engine drink the SF.
