Seafoam killing O2 sensors

I would like to know how many people exactly have had a check engine light come on after doing a seafoam treatment? My truck was put in the shop this morning because of a check engine. As you can tell from a previous thread this is the second time the light has come on right after doing it. Doing a little search I have found several people have had this problem between here and TTORA. Also thinking about it my fathers Van also had this problem soon after running that stuff through it.

Please let me know. I wrote an email to Seafoam and want to get a count.

Thanks

Next time try AMSOIL Power Foam

I've run it twice and no check engine light.

Ive only done it once but no issues, helped out alot to say the least. :shrug:

next time go to autozone and rent a scan tool to read the code. I use to put sea foam through my brakebooster but my cylinder 2 started to misfire. When i was on my way to go fix the problem, it just went away...some ppl said it mustve been a piece of dirt infront of the spark.

I love seafoam, and running through the brakebooster is the best...but i really dont want to deal with anymore problems with my truck.

Well I just got word that its not an o2 sensor but some throttle body sensor. Ill find out more later :shrug:

No problem with mines when I used it first time around... It is time for another seafoam.

So Amsoil has one as well? Same idea or better?

it's probably the same crap...there's not much to the product..basically just napthalene, isopropyl alcohol and pale oil..

Never had a problem seafoaming either.

Whats seafoam?

Some one tell me im a rookie lol:silly:

It's supposed to remove carbon deposits by running it through your engine.

I seafoamed my engine, let it sit, started her up and took off down the street whacked 'er open heard some detonation and check engine light came on... on my way back home I stomped 'er and no detonation. Autozones scanner had some broken pins so it couldnt read my ecu, so I disconected the batt. and no light so far.

I seafoamed my taco yesterday. Sucked in the brake booster, let her sit for 10 mins, fired up on the FIRST TURN, no hesitation, smoked good, took her for a spin 'roudn the block a few times till it stopped smoking. When I left later for work the idle was SMOOTH and the throttle felt great.

I've run it twice and no check engine light.

X2:shrug:

I wonder for those who are getting check engine lights "CEL", are they pouring a big amount into the hose or location.

I know this topic has been hammered tons of time.

Sorry how long this is. This response makes sense :shrug:
Sea Foam is sorry you had a coincidental failure of a system component that reached the end of its service life after claiming to have used Sea Foam Motor Treatment in your fuel system.

Let me assure you that that failure was not caused by Sea Foam.

Service lives of components supplied by OEM and aftermarket Manufacturers are affected by quality of the component and the components it is made of/with, time, heating and cooling cycles, and other outside factors including restraints set by OEM manufacturing costs for the component.

Sea Foam can not cause any component to reach the end of its useable built in service life any sooner than that which is engineered in by the manufacturer and/or be affected by outside factors.

An example is an O2 sensor. These highly sensitive "exhaust gas" readers transmit data to the engine management computer which is loaded with parameters concerning this data, and set or turn on a warning light when received data does not fit parameters stored.

O2 sensors are heated excessively and cooled many times daily, are subject to the corrosive nature of the exhaust gasses, and coat themselves with residues out of the exhaust which changes readings sent to the Engine Management computer (electrical resistances) to set air/fuel ratio's.

They Fail, it is built into the sensor by the manufacturer, they all eventually fail! They can not live forever under the conditions they are subjected to!

Does Sea Foam affect an O2 sensor, either good or bad?

In most cases, Sea Foam cleans the thin metal cover which protects the "Reading" part of the sensor. How close or far from the cylinder makes this happen or NOT HAPPEN! A clean, easy to heat and cool cover is GOOD, in most cases. The covered sensor may not be reading correctly, however due to other factors.

A dirty, worn O2 sensor does not transfer heat properly to the resistance unit, or stays to hot too long or doesn't heat up enough at the proper time. That Can Turn on your Check Engine lite too! It's outside the needed parameters!

So Sea Foam is either a good guy or a bad guy depending on whether we help extend the life of a manufactured component by cleaning it, or clean it and now the system reads it is out of spec because the service life is used up.

In any case, if you get 50K to 150K service life out of that component, and it fails, That failure was built in to the component by the OEM manufacturer at the request of the vehicle manufacturer. And you got your service life out of this "Wear" component. Thank Your Government elected officials!

If they fail before 50K, the government makes the OEM Manufacturer replace it at no charge under Emissions Standards. That is all the "Consumer Protection", you are guaranteed by your government, that you won't have to spend your hard earned money to replace it before 50K.

If they made that standard 150K, the manufacturers would surely build one that is more "Bullet Proof", but then they couldn't sell any aftermarket ones, and that is bad for business.

Any product introduced into an engine that can raise exhaust temperatures (certain additives in commonly available gasoline's like ethanol and commercially available fuel treatments that are CHEMICAL) usually affect an O2 sensor NEGATIVELY. Sea Foams exclusive 100% Petroleum formula (no chemicals) does not heat the exhaust and affects are POSITIVE.

Hope This Helps your understanding!

I use it like beer and have never had any problems. I run it in my Taco, CRV, tracer, lawmower, snowblower and the list goes on.

Same here. I've ran it through countless cars, both new and old, as well as lawn equipment, generators, pressure washers, etc, and never had a single problem.

Next time try AMSOIL Power Foam

power foam does the same thing..

the deposites in the engine if badly built up on the topside of the pistons as well makes the cats glow like crazy and then their basically trash after that..

So disconnect your exhaust before you use any sort of engine or deposite cleaning spray into the throttle body..

I've had o2's go bad soon after foaming the engine some with very little miles some with lots of miles but I have seen a trend and the o2's going bad happens within a day or so after the foaming of the engine..

cats and o2 sensors aren't cheap..

Well im gonna get some and run it through my motor it seems like it would do me good im at 48k miles.

When you do it, do it close to dusk so you can watch your first cat glow :waytogo:

i've run seafoam through my red truck, twice, no cel
ran it theough my green truck once (half bottle), no cel
ran it through my subaru, no cel
ran it through my friends 2.7L taco, no cel
ran it through my friends 22re 4x4, no cel.

never had a problem with seafoam... only good things to say about it.

you more than likely didn't have any nasty buildup in the engine..

I'm guessing that old Dodge of mine must have been a filthy whore because after 1100 miles worth of o2 sensor, I foamed my engine and the caat glowed at idol (as I was spraying it) and my o2 died..

carburated feedback system, mite have made the difference?
late 70's early 80's electronics sucked..
But its just too convenient how instant I had those failures..

i remember when i first ran seafoam, threw a check engine light that as related to the first 02 sensor. even got it replaced by toyota under warranty and it still threw the code. turns out it was a loose ground in the engine bay.

Removed a plug and tried to start my engine.....check eng light came on
seafoamed.....check engine light came on

First time was my stooopid a$$, whipped out my actron 9145 and cleared....no problemo!

The only reason I have a scanner is because my wife wanted a Mitsubishi 3000 GT. If you get a 3kgt....You'll need a scanner.

I put a whole can in my booster. Check engine light came on because of misfire which you know is going to happen if you use a whole can.

Cleared the code...500 miles later...no light.

For closure.....It has been my experience that a misfire is easily possible on old spark plugs resulting in an engine misfire....Hence the check eng light.

The price on the scanners have dropped.

Clean the sensor, clear the code, I'll bet life will be good afterwards.

Just 2 cents from an ignorant redneck that is still learning.
