Smokeless Seafoam

Just finished running Seafoam through my 94 GT's brake booster line. After letting it sit a while, per instructions, I started it up, anxiously waiting on the smoke show. There was none.

I have 144,000 miles on my car, so I was expecting to have the fire dept. called on me, but there wasnt even a hint of smoke. How likely is it that my engine is that clean? Is the smoking related to how it's ran, either PCV or booster line?

There was no smoke from mine on my 100k mile engine either, but I did notice an improvement in driveability. I wouldn't worry about it. As long as the seafoam gets into the combustion chamber (both PCV and brake booster do this) then that's the right way to do it.

Thanks man, I did notice the slightest of improvements, but I wasn't sure if it was just in my head.

I feel slighted, though, I wanted the smoke. Is that so wrong??

not at all, I was disappointed at the lack of smoke as well.

I always thought you did it with the car at idle, and have someone blip the throttle to keep car from stalling. If done this way you'll get more smoke

You pour it in while the car is idling, but once it's all in, you shut the car off for 15 minutes.

Thats what I thought, but I got more smoke while pouring it in than after restart.

Well ..... when I use it (in the brake booster)...... I run the car, put it in, then the car will die when it gets in there. Start again, put more in, car dies again. Plug line back up, start car, watch smoke pour.

What's seafoam?

yup, start sucking it up and as the motor starts to die pull the hose out a bit so it stays running. When the bottle is about 3/4 gone go ahead and let it stall. That will keep the seafoam inside the chamber to do it's job. When you start it up after 15 - 20 minutes it will smoke. It will also smoke for a few miles of driving when you accellerate

yea, I did it at 92k miles and damn, i seriously thought the fire department was going to come. Oddly enough though, I didnt feel a real big difference in performance.

My seafoam experience w/2 cars:

I did my car, and my parent's v6. My car, which has 61,000 miles, had no smoke at first, I gave it a tiny bit of throttle, up to about 2K, and the smoke started flowin, but it wasen't a ton like I've heard on here from others.

The v6, about 94,000 miles, had much more smoke.

Didn't notice much with my car, as it already runs how it should, but it was a bit more smooth. The v6 however was noticeably smoother, with a definite couple more hp.

This might make me sound we-todd-did but I've been thinking about something. When I ran it, I pulled the hose off of the vacuum tree and fed it down into the brake booster. Is this right? Would anything happen if I pulled the hose off of the booster and the seafoam flowed the direction of the vacuum tree?

120K here and had no smoke at WOT and no gains. so i guess that means that it was well taken care of... this makes me happy.
