Post Sea Foam question Options

[massbrandon]

So after running some sea foam through my car on Monday I noticed something. While having it sucked up into the engine some smoke started coming out from under neath my heat shield . Could someone possibly tell me what this is? Also, on a good note, the sea foam worked awesome. Car idles a lot smoother, accelerates a little better, and I have gotten better gas mileage after that and a new oil change.

You only have to change your oil if you add the sea foam into your oil right? I mean if you suck it up through your vac or add it into your fuel it doesn't effect the oil at all. This is one thing I need to do to my car. Since I here that high mileage cars shouldn't be seafoamed due to worst things will show up after sea foaming.
