Default Sucking SeaFoam up through PCV

I've done my fair share of searching...but I need some more clear directions.

I plan on putting some in the gas tank and oil tank and I also read that its a good idea to suck it up through the PCV valve (if I can find it and fit my hand down there).

a) which end of the PVC line (valve or hose)?

Ok and here is the PCV valve and tube. Do I want to be sucking the seamfoam in from "A"-->"B" or from "B"-->"A"

I'm guessing B-->A, but it'll be pretty obvious once you take one end off...it's whatever end has a vacuum. If it sucks it in, you're good. If it doesn't, try the other end.

thanks for the confirmation. I'm ready to roll...wish me luck.

Plan is to do the seafoam saturday morning and drive around over the weekend and then get an oil change this coming thursday since I'm due and I read that its good to put a few miles on the car before getting an oil change after a seafoam engine treatment.

again thanks for the confirmation.

only if you put it in the crankcase. changing the spark plugs is only important if you're sucking it through the intake somewhere.

well I plan on sucking some up through the PCV valve as well and pouring some in the oil reserve.

as well as another half can in the gas tank after topping it off with some premium.

here are my plans....stolen from here

# Park car in a well-ventilated area.
# Start car and run until it reaches closed loop (generally 5-10 minutes, and above 160°).
# Open hood.
# Unplug PCV valve
# Place end of hose into a shallow cup containing 1/3 of a bottle of Seafoam Motor Treatment. Allow it to suck liquid out until the engine starts to idle noticeably lower; then remove the hose from the cup. Do not pour enough to stall the engine yet.
# Repeat the above until between 1/3 and 1/2 of the liquid has been used.
# Now let enough of the liquid be sucked in until it stalls the engine.
# Turn off ignition.
# Replace PCV hose.
# Pour the remaining 2/3-1/2 of Carbon Cleaner into crankcase (through the oil filler tube).
# Pour other full bottle of Carbon Cleaner liquid into gas tank.

but I think I read somewhere that I should remove the PCV valve before starting the engine and also turning off the engine before replacing the PCV valve. I'll check it out.
