Seafoam

[Kaotic Lazagna]

Wow, 2 bottles for the crank and 2 for the fuel tank sounds a bit overkill.

If you live in the midwest (or at least around here), they use at least 10% ethanol in all the gas, 20% isn't that far away. Ethanol might be clean and renewable but causes carbon buildup like crazy.

I'm at 21k and notice a big decline in performance since a couple months ago. I plan to run some seafoam through the brake line and gas tank (50-50), but not the oil.

Has anyone seafoamed their intake with relatively low miles? How much smoke?

[talnlnky]

used it on a 454 in a chevy.... restored a TON of power that was missing due to carbon build up.

Yaris... ehhh... i wouldn't worry about it until 100,000 because its not a utility vehicle. Trucks and SUV's seem to have much worse issues with carbon buildup than small cars like ours. If your MPG's start to drop, or your car starts to feel like its not getting full power, and wasting gas... then check your spark plugs... if they are good.. then, yeah.. maybe a can in the intake would be good.

If you use top tier gas like Chevron, then there is no need to put it in your gas tank.

wow.... that would dilute the oil..... possible damage imminent.

I just got done running some in the brake line only mine with 21k. Holy smokes! There was TONS of carbon in there!

i'll be running sea foam into my car, i've got 60k and its definitely time to clean the innards out. i'll post pics of where I run it for those who need them. I did this on my mustang through the brake booster vacuum line and it smoked at least 5 houses around me... my stang had 80k on it. lets see what my yaris does tonight :-)

Found a good place to introduce seafoam i did a treatment on my car the other day. Remove the engine cover and follow the hose fromt he pcv to the intake. Disconect it there and use that vacuum source. Feeds directly to the intake manifold. I had little over 20k miles the amount of carbon buildup inmy car was insane. I only use good gas too.

I've gotten into the habit of adding a can of Seafoam to the gas tank in my cars about every 5k miles.
It keeps ther fuel sys clean.

BTW, Seafaom is also fuel stabalizer for up to two years.

Yes Photos of this vacuum line would be great!

huh ? ethanol CLEANS carbon and deposits.

what do you think is in half of the engine treatment formulas ?

ethanol ALWAYS means reduced soot and buildup. always.

unless you opened up the intake manifold and took a look see, I doubt you had anywhere near what you thought you had for carbon buildup. Seafoam will burn dark even if you don't have carbon buildup.

I plan on using seafoam some day... but am hoping the day won't be until I reach 100k... tho, it may be sooner (like 60-80k)... I will continue to monitor my mpg's to make sure they don't start to slide for no apparent reason.

The day I do seafoam, i'll probably do a gang of other stuff too... MTF, Spark Plugs, Coolant...maybe even brake fluid. Good thing I know I have at least 1-2 more years before I even need to think about that.

[Kaotic Lazagna]

Yeah, it'll smoke white regardless of how much carbon buildup you have. You'll know more by looking at your exhaust tip and seeing how black it gets.

Anyway, here are the possible vacuum lines. Red circles are courtesy of Thomas. Yellow circle is the line I used.

[Hard_Yaris]

Sweet!

Thanks you guys!

[Hard_Yaris]

WOW what a smoke show the seafoam provides.
Did the seafoam soak/carbon blowout today.
Shes purring real steady now.
i have about 108,000KM
I used the Yellow circle vacuum line.

[marcus]

i wonder how effective this is??

Correct.
Gas with 10% ethenol will burn cleaner even though it will reduce MPG slightly.

Another common ingredient in engine treatments is jet fuel (sans the aditives) which is just high grade kerosene. This is what they usually mean by "petroleum distillates"

Let's not forger that IC engine was originally developed to use a throw away by product of the distilling process (gasoline) that was thought to be mostly useless at the time.

I use Seafoam myself but, I do wonder exactly what is in it.

[Betrivent]

Little input from me (sorry for thread res) I used the yellow line today. Works great.

The moment you pull it out from the module, thing, the car will start to sputter and die. If this happens either insert the tube into the can of seafoam (I just stuck the tube right in there, slowly, so it didn't flood out the hose), or place your finger partly over the hose - this should bring the revs back up.

I just did half the can tonight, I'll do the other half tomorrow morning before work and then drive it out to work.

[LuisPRTRD]

anyone used the seafoam spray??? it's the same right??
