How to clean carbon
I have about 35000 miles on my car and I was wondering what to do to clean the carbon off the pistons. I use shell V-powee 93 octane fuel only since buying th car new, but does anybody know of a way to clean out any carbon buildup that might be in there?

If you pour seafoam into your oil and get crazy smoke out of your exhaust you have SERIOUS engine problems.

Haz l33t wheelz.
i just slowly poured about half a bottle into a vacuum line, with the engine running, and took it for a drive. made my own smoke screen, haha. the smoke doesn't last very long, but the motor felt smoother after that.

Thats the most ridiculous thing I have ever heard. Please explain to me how oil gets from the crankcase into the combustion chamber. I understand if you are pouring it into the fuel, but your first comment was to pour it into the oil filler. Seriously, answer that for me.

He was saying that if you put seafoam in oil ONLY and get white smoke then you have a problem which he is right since there should be no way seafoam or oil should escape out of the engine other than the drain plug.
Adding seafoam into the gas tank or vacuum lines will clean up the carbon build up in the cylinders and that is what this guy is looking for.
Brakebooster line, throttle... or the easiest one the gas tank... just make sure there is not a lot of gas else it won't be as effective.

Sounds good. I have what's called a ventilation hose coming off the back of the motor going to the turbo, I then have a small line going from the FPR into the intake manifold. And another one going straight into the intake manifold.
kinda shadetree, but w/e

Brake booster line should be the easiest, pop it off and slowly pour in while engine is running....
here is a pic, not a cobalt but it looks similar
Right side of the engine near the firewall.
