Finally got around giving the old girl the seafoam treatment and as advertised, I laid a few hundred yards of white smoke through the neighborhood. I couldn't tell if the people I passed were cranky about it, because they disappeared behind a wall of smoke...

Anyhow, I now have a "service engine soon" light on and I'm not sure what to do about it. I have an Ultragauge on the way and am wondering if I can turn the light off with that.

Anybody know?

 

It is probably several misfire codes from all of the gunk being knocked loose. When I Seafoamed mine several years ago, that's what happened to me. The SES light turned off after a few drive cycles.

 

Yes the ultragauge can read and clear the codes. There's a chance the light will go off on it's own like was mentioned, but they'll prob still be stored.

 

Usually after a good fogging the spark plugs need to be changed, nothing like tossing liquid carbon on em to see if you can cover the electrodes 100%...... It's always recommended to require new plugs before you fog your cylinders. Might want to take a few of em out to take a looksee.

You gave me a good laugh with the "Seafoamed the neighborhood...." I can picture the white cloud......LOL!!!!

Did you know you can do the same exact thing with water? Just do it slower. When I want to blow carbon out I just step on the skinny pedal while rolling, gray cloud instead of white.

Thanks for the response but I'm not sure what you mean by "recommended to require new plugs before you fog your cylinders" if you're recommending that they be changed afterwards.

Did I miss something?

 

Typically you "fog" a motor on worn plugs. Once done you replace your worn plugs with new. You time the Seafoaming to when it's time to replace old plugs. In other words, don't Seafoam the engine using new plugs because you will more than likely foul them and have to replace them anyways......

 

Seafoam might bugger up your O2 sensors.
Be careful.

Please stop using this garbage. Sea foam is the automotive snake oil. No one ever posts about the benefits of using this stuff, only problems after its dumped in the intake.

Feel free to prove me wrong on the benefits of this stuff.
