Seafoam [exhaust leak from O2 dump]

[97redgst887]

OK guys i just seafoamed my gst today. I used the bov vac line anyways when i shut it off then restarted my car of course i had some smoke come out the exhaust but also i got a O2 dump and i had smoke coming out of that at IDLE does that mean the seal on my flapper is bad?

No, it does not mean the flapper is bad. What turbo do you have on the car? If it is a 14b, there are probably a couple of small cracks in the housing allowing minute amounts of exhaust to slip past. This is pretty much normal. I wouldnt worry about it unless it was large amounts of smoke coming out.

And I think you overlooked one of the stickies at the top of the newbie forum. Read it and follow it. http://www.dsmtuners.com/forums/showthread.php?t=148744

If it is stock, state that it is.

Seafoam is great for identifying exhaust leaks
