tell me about seafoam
 

im hearing all this talk about seafoam lately, and was thinking i should grab some up but haven't heard too many people talking about it, so speak up!

i've got this motor i just instaled, 160,000 kms, and the rear rotor seems a little weak, but anyways i just got it running after sitting 3 years :).

thinking i should maybe grab up this stuff? oh, is sea foam the brand name? or....anybody seen it in canada?. oh, and what can it do that MMO doesn't. it is similar? do you add it to your gas too?

here ya go and im sure u looked at the latest thread about seafoam "another satisfied seafoam user.."

SeaFoam is the name of the product. its in a white can. never bought it myself but always have read good reviews. also not sure if its liquid like/ gas like im not sure. just saw it at my local parts store. if you cant find it you can probably order it online

i want to know too, and mmo.............

Just dump a full can into 1/8 tank of gas and run the hell out of her. Within a few miles you will feel the power return as the apex seals are freed up (at least in my experience).

Don't add it to the oil unless you are prepared to change it right away. I don't use a vacuum line to add it either, just add to gas.

Seafoam works wonders..most Napa Auto Part Stores carry it..that is the brand name and appears on the can..the can is white, with a white screw top..it looks like most fuel cleaners..basically a clear liquid..I added to my gas and oil..I went a week before changing my oil..
here are my results:
less smoking at startup
recovered some horsies
and after changing the oil the Royal Purple still had it's purple color
so I was pretty clean to begin with
plugs and fuel filter are next
tho I used 1/2 a can for the oil and 1/2 for the gas
so I could probably run some more in the gas prior to the plug and filter change
haven't used MMO (im in an SE) but Seafoam truly works

For rotaries, does having the intake suck it in damage up the catalytics?

Sucking it in through a vacuum line is really just for piston engines. You have no valves to clean, so there would be no point. Just add to the gas and you'll be happy...

^^^^
I learn something new everyday. :icon_tup: Thanks!

hmmm... i ran some seafoam thru my t2 thru the manifold and thru the tank..worked wonders...we dont have any valves to clean but we still have lots of crap on our seals and our intake manifolds...i noticed a great deal more response and smoother idling...also used it on my 84 kawasaki...worked great!

For a really good quick engine clean, run about 1/2 can of Seafoam through a vacuum hose, or pour it down the primary barrels, killing the engine. Put the other 1/2 can in the tank and let it sit overnight.

as for mmo, to my knowledge it is still unavailable in Canada, seafoam can be found at like partsource, auto value. napa might even have it but ive never seen it at the one near me.

Honestly I ran it in my old bmw and s13 and didn't notice a difference. The bmw had over 200K on it and put out a lot of smoke and all but didn't really notice any difference. The S13 had 160k on the clock and it was a pile of shit, but never broke down and got me from A to B. I used it on that and it also put out a lot of smoke but I didn't really notice a difference (It never passed smog and still wouldn't lol) On both cars I ran the seafoam per the can's instructions 1/3 gas tabnk, 1/3 vacuum, 1/3 crank. And the next day changed the oil, plugs and 02 sensors.....honestly I believe it did clean out my engines but it didn't make a huge difference like most people claim...might just be me? Haven't run it through my 7 yet.

Pistons are way different from rotaries. 12A's love the stuff.

I made the mistake of leaving it in the oil in my Integra for the length of a full oil cycle. The car has started knocking over the last few weeks, and I'm not sure if its related. I changed the oil and it helped a bit, so there is a good possibility. Don't put it in the oil and leave it! Do it just before you change your oil.

Don't put it in your oil. Put it in your gas tank. Rotarys are special, and they love a monthly dose of seafoam if properly applied.

The more miles, the weaker the compression, the less efficient the burn, the greater the carbon buildup. That's my opinion anyway... :)

You've convinced me, I just ordered a few cans... Only problem was express international cost more than the product :hahaha:

i think we should apply to start geting sponsored by MMO or Seafoam with all the advertising we do for both lol...but yes seafoam is that real shit.

12A + 1 Can of Seafoam = Happy Rotary :)

I like this kind of math! :lol:

Ray, that video's hilarious. My neighbors would sic the Fire Department, and then the CARB, on me!

Guys so I should add the seafoam when the fuel level is very low in my tank ???

Gonna try that when I build the 12a engine I have laying around.

Im not sure how good it does for new engines (rebuilt) but before you take it out, add the seafoam to like 1/4 tank and go for a rip. Will make cleaning the parts alot easier.

fyi adding it thru the brake booster vacuum hose on the intake manifold isn't a great idea. seafoam is a solvent and does not play nice with the brake booster diaphragm. if any finds its way into the booster it'll eat it.

Besides agreeing with you're avatar completely, I had not heard of this before. I put it through my brake master in my Integra and nothing happened to it?:scratch: I don't see how it could get into the cylinder anyways because of the direction of the vacuum.

yeah, that's a sweet avatar. naughty vp nominee.

booster not master.

and yes vacuum goes the opposite direction. and there's a one way check valve. a solvent's a solvent and doesn't belong around the booster. better off spraying seafoam into intake with a spray bottle.

Or just use Amsoil Power Foam.

or just put it in the gas....

:crackup: :crackup: :crackup: :crackup: :crackup:

Come on you guys, you're taking the fun out of it. Pour it right down those primaries and secondaries with the engine revving.

I did it in my gas once, didn't feel much as when I went directly through the vacuum line. I don't know what happens if you pour it down the carb with it running, then drive it around when the can is gone... I choke my car with the last bit and let it sit atleast overnight.

Cant seem to get hold of this stuff in Europe, especially in Tenerife, Spain. But if anyone knows of anywhere that would be great.

I'd love to try it, but I can't figure out where I'd do it without seriously pissing off the neighbors.

I do it in a parking lot by a small municipal airport. When the wind blows towards the airport. No one uses that part of the runway. And the airport shuts down at 11pm.

Oh, and do it at night.

Pissing off the neighbors is part of the seamfoam process! :lol: Whats the worst that could happen? They call the fire department? They come and there is a real fire elsewhere and many many people die because the fire squad came to a false alarm? Worth it. ;)

or you could be nice and warn them lol, also try to possition your car so that the wind blows it away from someones house unless you don't like them...if you have to, get some popcorn and invite the neighbors over for the show lol

hahaha...you dont know how many looks i got when i did mine right in the middle of the day in my driveway....lol...i got, "is your car ok?..."is that normal?"....is your car on fire?"....."do you need help?"....all within like an hour...kinda got anoying...i wanted to post up a sign saying "using engine cleaner...smoke is normal...please carry on....do not call fire department..."

I just bought a car from a guy that put seafoam in the gas tank ran it for a little while, it stalled, then the starter went out, blah, blah, blah, whatever happened, this seafoam has been sitting in the motor for god knows how long....will ther be any ill effects from that? will I ever be able to start it again?

Well technically the longer it sits, the better. I just wonder if it will start eating seals though. Also, you might have alot of carbon debri coming out of the exhaust when you do get it running. But it won't hydrolock it, so I think you're good.

I just don't see why you should even bother with the smoke show. Just dump the shit in the gas tank and you won't have to worry about it. But hey, my teenage son doesn't listen to me either.....

I'm with kentetsu on this one.

I am just now trying the sea foam in my gas tank. The truck I sold to get this rx was a 1962 IHC Scout 80. The motor was original. AFter the tune up it still back fired often and died occasionally. I added sea foam to the gas tank and from the moment I drove it next it did not back fire or stall. It continued to drive better the more I drove it, until I sold it to get an rx.

I added it to the crank case of the Scout and regretted it. It caused some external oil leaks that were probably plugged with coagulated oil over the years. Then I had to replace gaskets or connections. But that show what it can do to clean up the inside of the motor. On the plus side, it showed where the weak links were in the sealing of the motor.

Guys I just bought this one from ebay

http://cgi.ebay.com/ebaymotors/ws/eB...m=160171203069

Anyone used this one before ?

With one bottle I can use it multiple times right ? or the whole bottle is for 1 application only ?

Thanks.

Thats expensive... Go to an auto parts store and buy 1 for cheaper

thats about how much i pay in store....and hes in dominican so it may not be available

yeah that's about the store price for me too, and well the first time i did it i only used half a can, but if your car's been sitting for a while i'd recommend to put half in the gas tank and the other half into the engine and let it sit over night, or a bit longer

Somebody should dyno prove that this stuff works. Take an engine that feels on its last leg and dyno a before and after.

It helped my GXL. I put 1 bottle into the gas tank and filled it up. Gained me 4-5 MPG.

I plan on making a before and after video. 3rd gear pull from 2000rpm to redline, with the camera on the tach and speedo for both runs. Should be a good indication of how effective it is.

Put a can in my tank this morning, and there was a very noticeable increase in power right away, especially in the lower rpm ranges. Good stuff. :)

on a personal experience...ive tried the gas tank first...then thru the manifold...i noticed a bigger difference after i did it thru the manifold...also, if you go thru the tank...you dilute the seafoam with the fuel...the reason why people go thru the manifold is because its a lot more concentrated...and able for more cleaning power...

Why not put it in an old empty Windex bottle or something and spray it into the carburetor while it's running?

Im not gonna lie, I follow the instructions on the bottle and stick it in a very low tank of gas and drive the shit out of it. Results are good, fumes arent bad.......
