I just did my sea foaming though the brack booster last week.If that is true my cylinder 5 & 6 had a lot of carbon build-up. I would hate to see the mushroom cloud for all 6 cylinders if I was just cleaning two before. WOW.

I think most of the cloud is the vaporized Sea Foam, not really the carbon.

I diagree. I thought the same thing until each time I did it I got less smoke. But that brings up the question if you give it too much too fast it might overload it and vaporize some seafoam. I tried to use about 1/5 the bottle each time.
I tried it two times with the choke all the way out through the brake booster (engine did not stall). Then two times with no choke and let the engine stall.
You guys aren't big on reading directions are you?
YOU ARE SUPPOSED TO POUR ENOUGH IN AT ONE TIME TO KILL THE ENGINE.
Don't ask me why, but it's on the back of the can. Don't worry about 'hydrolock', seafoam is combustable, like spraying WD-40 in the carb.
The directions go something along the lines of: use 1/3 in the brake booster line, 1/3 in the crankcase, 1/3 in the gas tank. When puting it in the brake booster you add it slowly at first, but eventually you add enough at one time to the point where the car will stall. Then start the engine again, and finish up the 1/3 application.

I could not get my cruiser to stall...it sucked 2 colmen sized cups in...and it still din't stall all i felt i did was kill the ozone layer...nothing more....cruiser ran the same after that..
Yeah, mine did not die either, so after sucking down about 2/3 can (my truck, that is 
) I shut it off and let it "soak" for 5 minutes. I was wondering if the smoke was the Sea Foam itself vaprizing, but during the second treatment a week later the smoke was less intense and lasted only about 1/2 the time.
I used the brake booster vacume line because I have no carb to pour it into - EFI on FJ62 Any suggestions on a better port?

But is it true about only getting into two cylinders when using the brake booster method?
I didn't use the brake booster port when I did mine...I think I used the one for the PCV. It's been a while...but it was a 3/8 hose that came from the very center of the manifold.
I didn't get it to stall either. I just shut it down and let it soak for 10-15 minutes. Only got a little smoke and it cleared right up - but what smoke I did get was black/tanish and thick.

My smoke was thick and white.......
anyone got a pic of brake booster vac line? dont want to pour it in the wrong line. which seafoam? the auto parts place had dif. ones. i bought one and put the whole bottle in gas tank. no dif. that i can register.

First off, you don't pour it in. The brake booster VACUUM (sp) line draws it in.
It's right there on the brake booster, which is the large round thingy near the firewall.
Ok, that's a really bad description..... someone post a pic for this guy.

You fellas reading the premise of this thread?
Fuel goes into the carb where it atomizes.
It's distributed to the cyl's by the intake manifold.
Anything you want to introduce into combustion through brake booster vacuum is downstream of the carb, on the last branch of the intake that feed only 5 and 6.
How the hell is anything supposed to get into the rest of the cylinders from there!
Some kinda reverse osmosis going on in the intake manifold I don't know about?
It's probably not stalling using brake booster vaccum because you're only feeding 1/3 of your pistons, and the draw may be too little.
With EFI, your choices are limited.
Let's follow the logic and take it from there.

CRAP.... I used the brake booster line. And have since changed my plugs, cap, wires, rotor, oil, air filter, fuel filter, pcv valve. Thinking that I was going to blow all that @#$% out and then install all new parts. I guess that I need to start over and pour some down the carb so I clean everything not just cylinders 5&6.
another intake location for Sea Foam
I don't have my 2F anymore so I can't check but could you use the EGR input to suck in the sea foam? It would migrate to all cyls that way.
Somebody told me once that pouring SF down the carb was "bad" but I don't remember if I got a reason...
