Seafoam on engine valves

[Mi|<E]

So I happen to have two heads, one from a 250k BP which was serviced
always at mazda and a B6 head which was mine for ~40k and seafoamed
twice. I thought id post up with actual pictures about what the seafoam
does to the intake and exhaust valves. It is most interesting.

(The heads are both within 10% kilometers)



The most surprising is the intake valves:



You can see the intakes are super clean in comparison to the BP valves which
have a noticeable gunk build up on them. All the intake valves ridges can be
seen, the results are very uniform.




Now onto the exhaust valves:



Not as much difference here but a difference in cleanliness is noticeable. Im
going to attribute this to the fact that the 94 B6 has EGR and the BP does
not. EGR is bad.

very cool! nice to know it actually works and i wasn't spending my money on a couple minutes of thick smoke =P

Is there a SeaFoam that you spray into the intake?
I think it's the EGR, and PCV that do that, since the oil doesn't get on that part of the valve, unless the seals are bad.

Its just regular seafoam you feed in using the brake booster line
vaccuum. Half a can at a time, let it stall engine, wait 15 minutes
then start it up and enjoy the smoke show.

Cool! I thought it was just an oil treatment. Good to know, and see results.

Any other benefits from seafoam? Aside from reducing gunk/improving performance?

fuel injector cleaner, water remover, diesel anti gel, etc etc

Any chance of finding that stuff in Canada?

Partsource should carry it...

Autovalue usually has it too

Does this affect a turbo ze in any negative effect? I seafomed my ze when I first had it around 20k miles ago. At the time I had bad turbos, leaking oil into the intake. Intake valves look good(looked at them from the IM side) but I dont know.. does seafoam kill wideband o2 sensors?

Napa carries it too, in Canada.

I know these results... there are amazing ! I want the stuff ^^

it says on the bottle "safe to use on all oxygen sensors" and since bmw and VW use WB02 sensors, i would pressume it's ok. but don't quote me on it.

To the "directions" as to how to use it...
i always pour it in on the TB nipple, since you want it to run on as much of the IM as you can, to clean it all up and get spread out "evenly" througout the mani.
Use a vacuum line and the TB nipple...then about half way down the can, just dip the hose in the can which will stall the engine. let it sit for a couple hours...not just 15 mins, to let it disvolve real good, then start the car and repeat.
personally, i'd leave it overnite. and i use a syringe to make it easier.
DO NOT do this in your garage!
