Re: B5 S4 seafoam

Introducing Seafoam through vacuum line would clean everything down, but injectors.
Unless one floods the engine and leaves for no less than 2 h - carbon cleaning is hardly effective.
The dense white exhaust smog is a sign of effective cleaning.
Oil change is a must.

The pricing of Seafoam(pale oil-linseed oil, naphtha, isopropyl alchohol) is quite boosted here, (half price in the US).

I’d look at

Liqui(lubro) moly site (Germany).

LM2001 - VALVE CLEAN

LM2007 - JECTRON

Used from the tank (3-4l of gas) or with their cleaning device (introducing the mixture into the fuel rail).

If one prefers domestic products:

Try WD-40 (from the tank) - attractive pricing.


Looking at the MSDS of the different products=> everything gets spun around:

-kerosene
-naphtha
-mineral spirits



When I've got mine 4000 Q (years ago), the pressure test showed:

One cylinder dead
One cylinder half (82psi)


 15 min Lubro moly => all five cylinders - 174 psi.

Hope this helps,

Re: B5 S4 seafoam

Every shop that has Altrom and Worldpack products:
-Napa
-AutoValue

Most of the performance shops do have them.

Re: B5 S4 seafoam

Purging the fuel system (and decarbonisation) once a year should be enough for most of the cars running brand names gas with full additives package.

The original conditions for purge:

15-20 min idling.
Change the rpms up to 2500, keep the rpms 2-3 min between changes
No more than 3,5 l of gas (or double the agents).

WD-40 would be 5 times cheaper.
