I gave my car the seafoam treatment tonight, and I think it exposed a potential problem...
First off, make sure you use that stuff outside, not in a garage. I'm lucky it was windy tonight, and that the garage had a back door.
When I was feeding the seafoam in thru the vacuum line nipple, where the DV hooks up to the intake on the front of the manifold, I notice the fumes coming from the turbo side of the engine! Upon closer inspection, I could see some of the seafoam leaking out of the seal between the exhaust header and the turbo, hitting the hot turbo, and getting me high from the smoke. :-(
Is this a problem, or does everyone else see this when they seafoam? Can I just try tightening the bolts holding the turbo to the exhaust header? Or should I try replacing that seal/gasket? It is hard to replace?
I have a 2004 with 60K miles, and the seafoam made a bigger difference than I thought it would. Acceleration is now very smooth. The engine also runs quieter... Not sure about power, its harder to tell because the car does not surge at all while accelerating. I'd highly recommend trying seafoam, its super easy to do.

try tightening the bolts
Are you modded at all? The bolts shouldnt be loose on the stock turbo. I saw the same thing when I seafoamed but I have a GTRS kit and my manifold bolts had backed out slightly

I didn't use Seafoam but used BG prodcuts instead as recommendeed by APR
My local Audi dealership was trained this summer to offer the services and I had a fuel and oil system flush done.<ul><li><a href="http://www.bgprod.com/home.html">http://www.bgprod.com/home.html</a</li></ul>

Normal. Intense vapour pressure in manifold as witnessed through tailpipe smoke. A restrictor would-
be best on the hose that goes into the Seafoam/Berryman's. Less solvent at slower pace would clean better anyway. I've basicly went back to Berryman's spray or Gumout shot into the intake under the edge of a rubber boot...somewhere AFTER the MAF. I hear a cool engine is better. Ona car with over 50k or unknown service, nothing wrong with a good 'ol piston soak with whatever leftover solvents and MMO/2cycle oil you have.
re: the smoke is also caused by different areas of the engine and manifold getting hotter than usual and burning off crap from the outside of the manifold and plumbing.
