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.

Yeah, I read that its fine for high mileage cars. I have had nothing but good things so far.

The reason why most people don't recommend on higher mileage engines is because after putting seafoam into your oil it'll eat up all those sludge that was build up in your engine and will cause oil leaks thats been covered by the build up after seafoaming. If you have a higher mileage engine just suck it through a vac line you should be fine.

And yes you need to replace your exhaust manifold gasket theirs a leak their keep an eye on your engine bay too when your seafoaming it'll tell you where you have bad gaskets or leaks that you need to replace or take a look at.
