If you were trying to clean the intake manifold and valves, why would you suck it into the valve cover? Never mind that the valve cover usually vents out of the engine, not into



The vacuum line to the brake booster is a pretty good place to suck the seafoam/b12/etc in through.... goes right into the manifold, usually plenty of hose to work with.

no no no, disconnect it from the valve cover. the hose that runs from the valve cover to the intake tube and sucks out of the valve cover into the intake tube.
