I think I'm going to give this stuff a whirl. I was cleaning the throttle body and shined a light down it and things looked black farther down.

Can one of the little vacuum tubes on top of the TB be used? Or the vent tube that comes off the driver's side valve cover and attaches right before the TB? It seems like the PCV tube or brake vacuum tube wouldn't cover the area as well as coming from the other two mentioned above which would hit everything directly down the TB, not from the back side.

Opinions??

 

If I where you I would remove the intake chamber and clean it out first. Then if you still want to seafoam you can. You can also use the Brake booster line to introduce the foam.

The seafoam is not going to clean out your intake chamber like you may be thinking.

 

You can do it that way but most use the brake booster line because it is large enough diameter that you can get sufficient seafoam into the engine to cause it to stall (which you want to do right before you let it sit).
