Tried Seafoam on my car with no smoke? did i do it right?

The liquid coming out of the exhaust pipes...is just plain old water. Its just the catalytic converter....doing its job

I would put Seafoam into the gas tank to help clean out the injectors...

THAT...is where you'll get the smoke lol

Nope, you get the smoke by putting SeaFoam in the intake or a vacuum line. If your engine is clean, you may not see much...it is when there is built-up carbon that it makes the smoke show.

Ehh this can be debated, some people say the carbon makes the smoke. I whole-heartedly disagree, seafoam is an oilbased product the smoke comes from the oil

You should be seeing smoke no matter what.

It can be debated, but I have run it on cars for the first time and made enough smoke to engulf a two-story house. Doing the same thing one year later, the smoke was very minimal. I fail to see any other contribution to the smoke other than build-up in the engine. I have never seen smoke made when adding half of a can to an almost empty tank of gas, or adding it to the oil just before a change.

I also know a guy that gets similar results using water.

I always seafoam, we seafoamed our Jeep last year when we bought it brand new and still got the smoke show. Not once when I have used it, did it let me down in that aspect, that being said I also believe that the carbon build up plays a part in it and you will more then likely get more smoke with more build up. Now that brings me to the second part, some people also say using seafoam can hurt your engine as it breaks off large parts of carbon instead of breaking it down into much smaller pieces (I disagree because I have never seen huge chunks coming out of the exhaust).

Well driving habits also play a big role in the amount of carbon buildup present. If you drive your car hard often you'll more than likely not have that much carbon buildup compared to a car that rarely ever gets driven hard. My car barely smoked at all when I seafoamed it for the first time at 140K, but that makes sense since I regularly beat on it

So since you got some expierence... Is there anything wrong with doing this? Does it harm the engine? Is there ANY reason you wouldn't do this to a car? I own a 2001 Grand Prix GTP. No mods to the engine.

Done that to every car/truck I ever owned! Had the 07 for about 2 months and did it..didnt get much smoke but it did a little. My moms old ford...OMG! LOL I thought it was on fire it smoked so bad. But it ran better then when she first got it! If your going to use Seafoam do it the right way...go threw the vacuum line!

Actually thats kind of funny because mine did the same thing. But what I'm thinking is, is that I did it when my engine was cold and I hardly had ne thing come out. When my friend did his though he was at operating temp. Now that I think about it that actually kind of makes sense because the whole point is that you're trying to get the seafoam to soak into the deposits and then burn off. When it's cold its not going to do what its supposed to. Atleast thats my theory, which i'm going to test out tomorrow. It makes sense though, cuz pretty much anything you want clean usually involves heat like washing carpets, dishes, or clothes. The heat expands the molecules loosing them up. Anyway! My point is that I KNOW my engine isn't that clean, cuz when I cleaned my throttle body you can totally see the ridiculous amount of gunk that was built up, especially in the UIM. Imma seafoam my car again tomorrow at op temp and let you know what happens, but I'm pretty sure I'm right.
