seafoam = exhaust manifold smoke?

**B6driver** · 03-31-2008 11:45 PM

never used seafoam before... i used on front vac line, smoke came out the rear about after 1oz of the stuff being sucked in. the smoke in the manifold scared me a bit. does this mean i have a cracked stock manifold? or just a leak? it got quite smokey over the turbo...

I personally had the smoke out of the end of the tailpipe but I never saw smoke come out of the engine bay.... sounds like some type of leak...

Could be just a gasket.

usually if you see smoke around the turbo, theres a leaking seal around the turbo housing...find it and gl

Similar experience than mine, I actually saw liquid leak between the manifold and turbo, which probably means my gasket is leaking a bit. I'd also say your gasket is leaking.

yeah you have a leak for sure

If the leak was AFTER the turbo.....performance wise you are fine. But if the leak was PRE-turbo then you will suffer in the performance department!

Seafoam is notorious for eating up bad or soon to be bad gaskets. If you haven't replaced the gaskets ever then you may need to do so. On my 03 i had the OEM rubber ones and the seafoam ate straight through them. I now used polyurethane i believe.

i would guess its between the manifold and turbo... so yeah... i saw a little bit of liquid drip on top the turbo also..

i barely used an oz... i stopped as soon as i saw some smoke.

The smoke from the exhaust manifold is normal, it will go away after a couple minutes. All the extra steam/fumes from the Seafoam essentially pressurizes the exhaust manifold (and the molecules are smaller than exhaust molecules) so they leak out through the gasket. It will re-seal itself once all the Seafoam burns off.

im really more worried about the small amount of liquid dripping... but i will retest it if its infact steam, or something else. in any case, can anyone direct me to a new turbo - manifold gasket?

thanks
