sea foam

[Pirate]

I ran two bottles into the intake of my 1989 Econoline with a 302, as I wanted a 'deep clean', lol.

The result? I mosquito-fogged, the point of not being able to see behind me, nine miles of roadway....the smoke came out of the exhaust, and hit the low pressure area directly behind the van, fanning the smoke out in all directions....you guys would have been proud of me, as cars were having to stop for the wall of smoke I was putting out.

It ran a lot better afterwards, however.

I just added some SeaFoam to my almost empty tank, filled up, and took it for a ride on the e-way.

I don't think they sell Seafom in Canada, so I bought Canadian Tire "Carburetor and Combustion Chamber Cleaner" in a smallish black bottle. Does anyone know if this stuff works as well as seafoam? The instructions are similar.

Napa for the seafoam, as for the crappy tire stuff, I have no idea. Driving like an ass once in awhile seems to keep my engines pretty clean, I only seafoam them when I buy them.

Don't put too much in at once. You can hydrolock the engine if you're not careful.

What's the difference then between this and Marvel's Mystery Oil?

And isn't there some pink liquid stuff that can be dripped into the intake via an IV-esque jug?

I've used each of these - making eye-watering white smoke.

I've found Seafoam at CarQuest auto parts. It is 12.69 after taxes in N.S.


How long is ideal to let Seafoam sit and do its thing? I got a bit of a smokeshow today but not quite as much as I expected (they say drive for 5-10 miles until the exhaust is normal, mine was good after not quite one mile.) How quick do you pour it in? Do you want the engine to be constantly bogging down and surging or somewhat steady (as steady as a vac leak can be)


Letting it sit longer = better? I dunno how it goes. I Seafoam'd the car while hot and let it sit while I greased every hinge in it and stood around (pretending to look knowing), maybe 20 minutes total, and I did not put any in the crankcase, just in the gas tank and the booster vac line, fwiw.

I used it one time on my car, not much smoke. I poured it right down the carburetor (SLOWLY), after the engine was at operating temp, and let it sit for 20 minutes, if I remember right.

Started it up, and there was a little smoke, but not much.

You see, with the way that I tend to drive things, there are no issues with carbon or sludge build up. I regularly change the oil, and regularly hammer it.

Folks on the Dodge forum were discussing cleaning the throttle body from the sludge/ carbon deposits, so I checked mine. A light film, and nothing more. I'm never afraid to lay on the throttle...

I had a similar experience. Some smoke, but not enough to piss off the neighbours, it just sorta look like a blown head gasket or something, and was gone after a 1st gear lap around the block. This is with the combustion chamber cleaner I mentioned above, which a few people have indicated to me is basically seafoam.

I usually let it sit for about 15 min. Smoked less then the car usually does on a cold morning.

This might be worth posting in this thread. I have been emailing Seafoam company and getting good responses from a guy named Jim. When I asked why a can of SF that I bought one day was one color, and a can I bought off of the same shelf the next day was a completely different color and seemed to work much better, he answered;

Sea Foam is a multi use product and can be used in any type fuel and oil. Because Sea Foam can be used in diesel fuel the D.O.T. requires any additive for diesel fuel can not have any coloring and we had to remove the dye from our product. The only difference in the two cans is the color. To see any results when adding Sea Foam to fuel may require to run through a tank full of treated fuel.

I then asked how often it would be fine to run SF through my gas tank and manifold vac line;

note: The cruise control servo is also circular and very near the brake booster. It looks somewhat similar and someone that doesn't know a ton about cars could mistake it for the booster. I did. SF still worked but not quite as well as I had thought, that's why I bought the second can to run through. Since it's all manifold vacuum, it's all going to the same place, but might make a few stops along the way, and as such, you won't get as much SF in there as you had planned.

Looks like a bot answered the same twice.

Nah it looks like my dumb ass fucked up when editing my post;

*Because Sea Foam is a pure petroleum blend with no chemical additives Sea
Foam can be used in fuel as often as you like. We recommend using Sea Foam
in the fuel every 2-5 thousand miles and in the vacuum line one a year or
every 15000 miles. I add Sea Foam to my fuel every other tank full of fuel.

SORRY ALL!

b12 chemtool does the same thing.....only 3 bucks a can

Does anyone have experience with Seafoam products other than the motor/fuel system treatment?

[sly]

friend of mine likes to tout Auto-RX products. Don't have any experience personally, but the amount of gunk he got out of his engine over a few months was amazing.
