PCV hose ? . . . on the valve cover, it goes back to the intake . . . Be sure to let the engine suck it up at a snail's pace, . . . the smaller the line the better.

is it easy to pop off the valve cover? is has a rubber hose over the tube seems like. so no oil will come out of it when i take it off, or do i unhook the intake manifold side?on the driver or passenger side?

The valve cover has a rubber hose on both sides, pop off the passenger side, and add a smaller hose to it . . . small like fish tank hose. Wrap the extra space/gap with electrical tape. Crank the truck, and let it get to "warm" temp. Then pull the line off the side, and very slowly start to let the vacuume suck up the seafoam.

It needs to be sucked up slowly . . . like as in an ivee (sp) in your arm, slowly
