Not the same old SeaFoam thread...
 

So I asked a question a while back, and the answer that was given has been bugging me. I finally did the math, and here is the result.

Kentetsu suggests 1 can in 1/8 tank of fuel, and then drive the piss out of it to clean out the motor. That is 16oz of sea foam in (if you have a S3) 2 gallons, or 256 oz, of fuel. Ratio of .0625 oz seafoam/oz of gas.

I asked if you could put a gallon of sea foam into your tank and then drive the piss out of a full tank to really clean out carbon deposits. 128 oz of sea foam to 16 gallons, or 2048 oz, of gasoline. Once again, a ratio of .0625 oz SeaFoam/oz of gasoline.

I'm contemplating doing this, as it is no more concentrated than what Kentetsu suggests for a good cleaning. Any thoughts?

if you're concerned with seafoam eating up any rubber or plastic pieces, then add it with 1/2 tank of gas.

seafoam wont eat up your lines:icon_no2:

you worry too much and make sure you have a clean fuel filter after your done.i love this stuff:icon_tup:

OK, so if you want it more concentrated why not pour it straight down the primaries and secondaries while the engine is running? That way your smoking event happens in your yard, not while you are out on the road attracting attention?

If you really want to give it the treatment, pour enough sea foam into the carb to choke it out, then let it soak with occasional turning for a few days, it works wonders although it can be a little hard to start back up sometimes.

Done that also but with a 2 liter of water per rotor

My thought. That would be a hell of a lot more expensive than just using one can to a 1/4 tank of fuel. Seafoam is what, $10/can? 1 can for every two gallons. 16 gallon tank. $80 for Seafoam. Or just wait until your low on gas, dump $10 into your tank and be done with it.

if you dump 1 gallon into a full tank its gonna take that much longer to burn all of it off, and you're gonna have to do tons of driving, else you're gonna have the cops all over your ass until all that shit is burned off.....i'd either put it down the carb, or 1/8 tank of gas be done with it quick and get the same results since the concentration is the same.

I've done it in a 1/8 tank and it doesn't smoke.

i've done it both ways, of course pouring it down the carb lets more smoke out, waaaay more, but there was still some smoke coming out by pouring it down the gas tank.

I usually recommend the 1 can to 1/8 tank if someone has a motor that is in really bad shape.

For a daily driver in good overall condition, you can put it in however you like. I will add the Seafoam whenever I feel that the power is dropping off a bit, or before a big race or road trip. On those occassions, I'll just throw a can in with a full tank of gas. It doesn't really matter. You could probably use 1/2 a can of Seafoam and get the same results. It works fast, and it results in a noticable increase in power, both on my last (very worn out) motor, and on the new one.

What I really want to see is someone doing a dyno run. First without seafoam, then with it in the tank. I swear I can feel the difference, but I'm not sure if it is the cleaning action or the Seafoam itself that causes the increase in power.

I've used it about 5 times and so far no smoke at all. The only time my car really smokes is after it's been sitting awhile, usually over winter, and if I redline it and come off the throttle, then my worn out oil control rings let some oil into the combustion chamber and I get a nice smokescreen.

Can someone post a pic of the actual face of the can...

I've always been reading about this stuff but never ran across it in a parts store and have a 12A in desperate need of being woken up.

Thanks.

"Done that also but with a 2 liter of water per rotor "

Wacky, you are crazy. But I'll bet it works.

lol, love the random pic and link :lol::lol:

should be getting some this week. gonna try it in my se.

last year I ran water for each rotor. 1 gallon total i think.

another thing you can do is pour it down the carb, and let the car sit. Just get 2 cans. For the first one pour down the carb to each rotor. Let the car sit for 24 hours. Rotate the engine by hand 180 degrees at the 12 hour mark to make sure its goind around. Also do it counter clock wise of the normal engine rotation so that you're not just pouring it down the exhaust. If you have an old set of plugs you should probably put those in to not foul the plugs you have in there. If not, take them out and put bags or tape on there.

Next day with the spark plugs out, crank the car as much as possible. Have a blanket or big grabage bag infront of the plugs as it will shoot out quite a bit. Once most of it is off, put everything back in and start her up :D

This is probably the most extreme way of doing it.

Another deal is get the spray can of GUMOUT Carb and fuel injector cleaner. Rev and hold at 3,000rpms and keep spraying down throat of carb. Works wonders, really does. Easy to find. Then pour the seafoam in the tank to clean out carb internals and go for a drive.

I hate Math...lol

I think his reasoning is that even though it's just as concentrated, he'd be doing a much longer clean out. With 17 gallons (combined amount) of fuel/seafoam mixture.

exactly...

I havent tried a seafoam on an older cars with EFI. Is it really good in cleaning the injectors?

It hasn't caused any problems with my 4.3L Vortec CPI and god knows that thing is prolly as archaic as the SA in age. :lol:

i get the point, but the way i see it is for example cleaning around the house, you're not gonna clean the same spot multiple times when you know that you've already done it once and its spotless....its just something that you'll save up money and time if you just do it once. but in the end it IS his money and his time.

$80 worth of seafoam... Rebuild gasket kit only runs about twice that, if you want CLEAN...

This is basically why I say to run it through the gas tank, rather than dumping it down the carb or sucking it in through a vacuum line. All that smoke that goes out the tail pipe is the Seafoam that you just paid 8 bucks for. I see that as wasted product.

When you run it through the tank it does the job just fine, and I think it is a better bang for your buck...

x2 :lol:

I felt it when I ran it through the carb. WHen I ran it through the tank I hardly felt anything...

Not saying your wrong ken :) But your motor had 10x the miles on it that mine does. Mine just passed 20k, so if I cleaned it once then there wouldn't be much to clean off a 2nd time since it is fairly new.

I have been waiting longer than usual this time around to go through the gas tank. I have been thinking of doing what OP has said but on a smaller scale (like 3 cans to 1/2 tank or something.

Ken, how can you say making a Sea Foam cloud is wasting the product? It's like a free fire works show! Try it, you'll like it, tons of fun and great for the engine. There's nothing like soaking you're seals in 100% Sea Foam.

This treatment fixed a low compression problem I was having due to leaking oil control seals in the White One. Well worth a few bucks of Sea Foam!

I ran 2 cans in about 5 gallons of gas. Noticeable improvement. The tailpipe smelled terrible and smoked some at idle but no opaque cloud. Best to hit the freeway then fillerup.

thanks. I just brought back to life a 89 Volvo 2.3 turbo. It sat for 2-3 years and lucas injector cleaner didnt help much.

I'm actually on a new (used) motor that came to me with about 60k on it. The previous motor coughed up an apex seal at 213,000 miles. :)

And that cloud of smoke that comes from direct injection? Well, I view that as seafoam that has evaporated and then was pumped out the exhaust. I guess that's why I call it a waste, although there's no doubt that it still works that way. I just feel that you get a better cleaning with a more gradual distribution. I could be completely wrong though, thats just my feelings on it. :)

No you are exactly right Ken, what happens when you dump a bunch of sea foam into the rotors through the carb and soak them while spinning the engine once in awhile is that much if not most of the sea foam gets pumped into the header and exhaust. Then when you start the car, you get some immediate smoke from the residual sea foam in the rotors, followed a few minutes later by a huge amount of smoke as the sea foam in the exhaust system heats up and starts to burn. This huge cloud of smoke continues for several minutes until all the sea foam burns off, which is what gave me a chance to take the photos and video linked above.

I can't immagine that this kind of abuse would be good for cats or fuel injectors, but Nikki'd 12As with RB exhaust just love it.

Some call it waste, others call it cheap entertainment. But it saved me from rebuilding the 12A in my White One about 30,000 miles ago so I'm a big fan.

I added seafoam, didn't notice much but a choppy idle so far, I went on a abusive spin too.

How did you apply it? If just in the tank, you won't see too much that quickly from my experience. If its straight through a vaccum, its alot more notable expecially the worse the engine.

I added some into the carb and let it sit for a bit, also added a bit to the 2ndary barrels?

I also did this with premix a bit before and let it sit.

Started, revved after awhile.. another plume. It smoked for like 15 mins.

I'm bout to add the rest to the tank, just added a 1/2. I put one bottle in already and drove the piss out of it.

Seems to start quicker and rev smoother.

chopy idle is probably due to the fact that your car was possibly tuned while all that carbon was in there affecting it, so now that it's not there, you might have to re-tune it....just a thought.

If you could buy seafoam by the gallon it'd be really cool....

As it is, I have to go down to New York to get it because none of the local part stores here in Ottawa have it... and even then I just get the standard sized can.

Jon

the local advance auto sells it here by the gallon...it's like 50 some bucks

I've seen that too. The stuff dreams are made of :)

Hey Jon,

Any Napa, and Carquest store can get them in. If they don't have it on the shelf they can order it in for you.

Hi Everyone,

After reading here about this product, we decided to buy it in the US, import it to Spain and try it in some of the RX8 of the Spanish RX8 Club.

Last Friday we decided to put the product inside our SA22C and it is incredible!!!

The accelerator response is great, the punch from lower revs has increased, and even the idle is better (before we have observed some misfires running low on revs).

The way we used the product was the following;

1. Disconnect the Fuel Pump,
2. Disconnect the Fuel Lines in the Carb and start the car until the carb is out of fuel
3. Disconnect the Spark Wires
4. Drop SeaFoam directly into the barrels of the Carb (the small ones) while running the starter to put the Seafoam directly into the combustion chambers. (3/4 of a can)
5. Let the car standby one hour
6. Reconnect Pump, Lines and Sparks and start the car in the open air..... and watch the fireworks...

After that we have put the rest of the can in the tank with petrol, and run the car normally....

The results are great, during the first moments after starting you have a very irregular idle but after a few seconds the car runs great, and the more you use it the greater it gets....

Great product, Thank You all!!!!!!!!!!!!!!!

You will probably find that, unless the motor you are dealing with has sat for years, you will get the same results by simply adding it to the gas tank.

I dump a can in before every autocross event. It's like adding a small turbo except you don't get the lag...

Yes it does seem to be nice, added it to my bros 7 series bmw too haha, runs smoother. My fb took two cans, oddly I have this situation now when I hardly tap the throttle to start driving it'll sometimes stall... maybe it was too cold still though :S
