How do i: Use this seafoam..

[Midgear]

Ok, so i bought some seafoam for a grand total of 7 bucks and 76 cents.. took it home and had no idea where my PCV valve was, talked to BlackJack and he pointed it out, so i went out to pluck it off and suck up some of this seafoam, and i can't get to the pcv valve, its smothered underneath other wires / tubes and i cant move it.. where is the Brake Booster line? can someone post a picture on where this thing is.. ive searched and cant find anything.. I really dont want to move all those other hoses and wires out of the way to remove the PCV valve.. id rather leave them where they are

pics welcome..
