I have a question. How do you go about putting seafoam in an N/A fc3c? I couldn't find a sticky about it. I probably wasn't looking hard enough.

 

Pour it into the gas tank, fill up with gasoline. This is a Kentetsu question if there ever was one.

 

Ok just asking because I've heard of a few people putting it in a vacuum hose and in the oil. Just making sure so I dont do anything that could potentially ruin my baby.

 

in a normal piston engine you could pour some in the gas tank, engine oil and vacuum line on the intake manifold... Ive done that before. however, im curious as to if it will do a rotary any good or even if we should avoid seafoam in the UIM/LIM and engine oil...

 

I'd avoid it in a rotary. Rotaries like to have their internals coated/sprayed with oil as part of the combustion cycle (hence the OMP). Seafoam will interfere with that I think.

 

Thanks a lot guys. Thats why I'm cautious about putting things in my car that can go in pistons.

 

Why? Why waste money on any additive of dubious benefit? The vast majority of vehicles on the road never have any of this junk tossed into their fuel, yet seem to function perfectly well.

When an OEM starts recommending the use of any of these additives, then it may be something to look at.

Otherwise, just keep the vehicle in good tune and have the injectors professionally cleaned every 100K or so.

 

I can only speak for 1st gens, but they really seem to like the stuff. I tend to dump a can in the gas tank every month or two, and can always feel a difference right away. It could be that using a carb on a rotary results in more carbon buildup. I don't know.

I've also used it in my Audi and BMW with no great improvements, but also no issues. Maybe a slightly smoother idle if anything.

Not a good idea to pour into oil or gas, BUT a GREAT idea to feed an entire bottle into a vaccum line

I know this because I did it myself. Trust me, its what does the trick! The seafom will enter your intake, clean out your combustion chamber, soark plugs, exhaust manifolds, and all the crap and carbon that sits in your exhaust. It will smoke a LOT, but that is a good thing

The end result is the best idle your car has ever offerd it to you. Like I saide, I just did it to my 88 rx7 with 158k miles and now its drives 100000x better!

 

^^^ This is when users start running into problems... If you just put it in the gas tank, it will work fine without the possibilities of fouled spark plugs, flooding, etc.

 

water is cheaper and probably does more.

 

I don't know if water works any better, but I have been playing around with B12 Chemtool lately, and so far the results seem to be on par with Seafoam at about 1/4 the cost...

 

Its been a month since I seafoamed her through the vacum line and into the intake. Runs better, amazing idle, good startups, and smooth acceleration.

I wouldnt tell this to people if it didnt do me any good. For my gas take I used prestonecomplete fuel system cleaner. Something thats meant for the gas tank.

 

I'm not saying that it doesn't work, just that there is a much greater chance of screwing up when using a vacuum line. Many users end up with fouled plugs or a flooded motor when they try that, then we have to help get them going again.

Its just so much simpler to put it in the tank...

 

well, detergents will strip all the gunk out of the intake chambers where water won't do much there. but for the internals i'm not sure, i have had similar results with water as most other cleaners, but you do have to be aggressive about it.

 

we used water for years in piston engines and it does clean well , It goes through the intake without washing all the crap into the engine and steam cleans the internals very well .. a mixture I think it was of petroleum distillate and water poured through the carb at a large volume or vacuum line but you need a good supply so use one that will actually suck the mixture in ( a pint in a few seconds poured through the carb ) while working the throttle to keep the engine from stalling will produce good results .. the water keeps the fuel from igniting until a high ignition point is reached . then the super heated steam goes to work and blasts the hell out of the carbon etc. ( I wouldn't suggest water of any kind poured into a hot engine temp changes can be destructive )and keep your face back Just my two cents and a little fuel for the fire

 

I have also run seafoam through my 12A FB and it did seem to help a lot, better idle, cleaner throttle response, ran better, etc. I poured it straight in the gas tank and it ran fine for me. I will also be using a fuel system cleaner soon that should help clean out any deposits between my tank and carb. We'll see

 

Yup, you will get nastier plugs and possible flooding, only if the operater fails o keep the engine at high rev while the can is sucked into the intake.

I do strongly suggest changing the plugs after a proper seafoam. All that carbon build up gets splattered on them.

 

Hmm... This is interesting to me. My father uses this in my families vehicles (piston engines), and has had great success. I just wonder if this is "good" or "okay" for these engines...? It seems that a majority of you guys are stating the benefits of Seafoam, though. I like the sound of "better throttle response"...

Can anyone post anymore cons about Seafoam? (Any bad experiences?)

 

Hmrmmmm

 

Pretty much all of the threads you will find regarding an issue after using Seafoam will involve a non-startable car after sucking the stuff in through a vacuum line.

What you won't find is: "I dumped a can of seafoam in my gas tank and then my car wouldn't start"...

I've been using it for years. I add a can before I drive to a race just to freshen things up a bit. I've always had positive results. Others will always have their own opinions so take what advice you want. My advice comes from several years of personal experience, not just what I read on the interwebs.

 

pull a vacume line off and put the line into the seafoam you will prob have to have someone hold the idle higher while you do this.........iv used just water the same way aswell . with water is basically steam cleaning the inside of the motor..

be prepared for alot of smoke and i mean alot.. i had the firetruck roll by me when i did it with water

 

lol. Or, you can ignore my years of experience and listen to the new guy who knows better.

 

I was always wondering about seafoam and I would rather trust your words than a newbs! is there a particular amount of gas that has to be in the car?

 

Seafoam makes some really good cleaner. Tons of ppls rather use seafoam cleaner than lucas etc
