Seafoam

[ho1ywars]

not sure if this is in the right spot.. feel free to move..

alright, seafoam. who uses it? Good results? bad results? terror stories? Im thinking about trying it, but i have heard a couple bad cases and it scares me.

[Silverfc88]

I've used it before without any problems, but I don't use cleaners that much. When I do use them its either Seafoam or Redline fuel cleaners. This is on my Stro'. I usually can't tell the difference, maybe a better idle.

It helped my 83 prelude out alot.

[TROLL]

can you explain what it is and what it does? thanks,
bryan

[koho2731]

it's a carb/ fuel cleaner

[StealthTC]

I used SeaFoam in the Mazdaspeed, and every couples months in the Scion

it does more.
it can be added to the oil to "decarbonize" everything. i should have worded my original post. i was really wondering who uses it in the crank, with the oil. it doesnt really have any directions on the bottle, but im assuming since its real thin... you shouldnt really rev with it / drive with it in the crank. just run it a few minutes before changing your oil?

i've used it several times, and on my friend's cars
put a third in fuel tank, third in crankcase, and third through vacuum line.

lots of smoke, but usually helps make the motor run smoother and give it some umph back

Exactly what I did, only I didn't get any smoke...but it did seem to feel a little better.

I know a lot of people with 3000gt's and steaths use it to quiet their lifter ticks

I use it. It's always worked awesome, according to the butt dyno. I usually run most of a can through the motor, then just throw the rest in the gas. I have heard people put it in their oil, but I have not tried that yet. Maybe in the jeep for the next oil change. I'll post any results if I notice any difference, but I'm not taking parts off of it again unless I have to.

that would be awesome.. i really want to put it in my crank but im afraid.. haha. what do you mean you run it through the motor, through the intake?

[012.5RS]

I've never used it, but the company has been around since the early 70's i believe. If you talk to old school v8 motor heads, they will tell you how great it is.

When you run it through the motor, you pull a vacuum line off of your intake manifold when the car is idling and put the free end in the can. Just pinch off the line while youre doing it so you don't flood the motor with Seafoam. It'll put out this cloud of dense white smoke that looks like you can walk on it. then let the motor idle until the smoke starts to die down, then go beat the piss out of it for about 10 minutes. By then it should have burned off all of the Seafoam. You'll probably notice a difference right away if the motor has high mileage.

1. Turn the car on

2. Pop open any vacuum line that leads into the intake manifold. The brake booster line is preferrable since its thick and usually leads to the center.

You are going to want to use the line or lines that will let the most amount of seafoam spread evenly throughout the cylinders, otherwise only one or 2 will actually receive the seafoam.

3. Slowely let the vacuum suck in seafoam in about 2 table spoon increments, and then let off and give it some air. You will want someone to constantly tap the throttle so it does not bog out and die. If it starts to bog out, just let off and give it some throttle.

4. Once about 1/3 to 1/2 the can is used, turn the car off. The car will be smoking right now, and you will definately know if you have any header leaks (i know, i seafoamed a car that had huge leaks and could barely breathe).

Let it sit for about 10-15 minutes.

5. Turn the car on be prepared to drive around at at LEAST 4000 rpm constantly until you exhaust no longer smokes. I take my car up to redline when shifting and cruise at about 5600, just enough to keep it in vtec.

6. Repeat with the rest of the can once you no longer blow smoke.
Carbon is deposited in layers on your sidewalls, and the seafoam will remove it layer by layer, which is why multiple uses are required.

CHANGE YOUR OIL WHEN YOU ARE DONE


7. If your car has more than 30k miles on it, then you will need to do it MORE THAN ONE CAN to get the full benefit from it (because of carbon layering)! As a rule of thumb, perform 1 seafoaming per 30k miles, then once every 1-3 months after depending on what kind of hell you put your motor through (driving, oil quality, gas quality, etc).

8. Don't forget to buy a second can for your GAS TANK! This stuff works as a great fuel injector and valve cleaner. You can also add this to your crank case and drive for about 5-10 miles. Carbon is anywhere gasoline/oil is.

NOTE: A MUCH better oil crankcase and TRANNY cleaner/desludger is AutoRX. It works over about 2500 miles and slowely removes all sludge and varnish. Visit http://www.auto-rx.com or http://www.auto-rx.net

9. Change your oil after you are done. A little bit of seafoam will always leak past your rings into the crankcase. Whether you add it to your crankcase or not, gas tank, or brake booster line, once all the seafoam has been burned through you are going to want to change the oil as it lowers the viscosity of the oil which is not good.

10. If you feel like really getting rid of that carbon, then run seafoam through your spark plug holes.

With the car WARM, (and i mean slightly warm, NOT hot. Putting cold liquid in a hot cylinder is dangerous and can cause cracking.) Take your spark plugs out (make note of what wire goes on which plug, otherwise you will fck up your timing badly if you mix the wires). Put a very small amount, 1-2 tablespoons, in each cylinder. Let it soak. You may see it reacting with the carbon bubbling, or you may not. After 15 minutes, put the plugs back in and drive the hell out of your car (not neccessary to bounce of the rev limited, just 5k rpm) UNTIL it stops smoking, then immediately change your oil.

NOTE: The ONLY possible way this could "hurt" your engine is if you dont change your oil after using seafoam or if your engine is beat the fck down and held together by carbon seals. Once the carbon is removed, it would then reveal a leak in your seal. But your **** would have to be pretty beat to have bad seal leaks, and that will let you know its time to get new seals. Not knowing of a problem doesn't mean its not there


I guarantee you will feel a NOTICABLE increase in horsepower. Thats a big notice too. This is safe to perform on all engines with any amount of miles. You can buy seafoam at AutoZone for 5.99 a can.

Post any comments about your experiences with seafoam.
No, it wont blow your engine up. If it did, then you probably had seals held together by carbon. And you officially own a piece of ****.



This is something taken from a honda-tech site that has been debated for 7+ pages. After the full read i decided to take the plung....I put 1/3 in the intake mani, 1/3 in the crankcase and ran the piss out of it till there was no more smoke....While it clames to clean out carbons.... the safoam made its way to the vtec solenoid gasket on my motor and i had to redo that gasket to stop the leaking.

It does do some cleaning, nothing that compares to a hot-tank, butisnt magic in a can....Is it worth the 6 bucks for the 'sort of' clean youll get out of it? debatable.... but it sure is a blast to drive fast leaving a trail of smoke.

I also heard it could foul out plugs and it makes sense. So changing your plugs along with the oil change probably wouldnt be a bad idea.

[HondaGuy1122]

i have heard not to use seafoam if your cas has 100,000+ miles.


can cause damage.
