Here is an install guide for seafoam with pictures, so we can stop the 'how do i use sea foam' threads.
First Step: Check out their website - it has a lot of great information and lays down the basics for using their product: Seafoams general install guide

What does seafoam do?
It's a petroleum based carbon eater that supposedly cleans out your engine. The back of the can tells you what it is supposed to do - clean injectors, rings, fuel lines, basically everything you could ask for. Does it work? That depends on who you ask - it sure looks like it does from the thick white smoke that pours out of your exhaust after using it though...

Where do I buy it?
I got a can at AutoZone for 6.95 + tax, I would assume any autoparts store would carry it - remember though, seafoam is a bit more then just a brand name of engine cleaner, it's more of a univeral products so using other items labeled as just 'engine cleaners' might not use this same install/use process.

How do I do it?

General guidelines:
Get your car outside and parked in a well ventilated area. The basic steps to using seafoam are: insert .5 pints to 1 pint (1 can = 1 pint) of seafoam into your gas tank; the tank should be filled up atleast half way. Add 1/3 to 1/2 pint into the crankcase by way of the oil system, let sit for 5 minutes, then rev. Add 1/3 to 1/2 pint directly into the injector and air system, by way of a vacuum hose (atleast for celicas).

Detailed:
Get your car outside. I started with the injector system. Basically, you need to find a way to get a vacuum hosed hooked up from the intake manifold and into a can so you can slowly pour the product into the can, and then have it sucked into the engine. This is more complicated then it sounds, because you have to find a vacuum house that can be easily accessed and moved around. Most people, as recommended by the general seafoam guide, use the brake booster line to accomplish this - I found that to be too much of a pain in the ass, and luckily for us Toyota decided to add a little vacuum hose attachment point for our convience :D.

This pic is obviously for a GT-S, but I think all GT models have something like that in about the same location. It's a small metal tube that extends out of the intake manifold, covered by a little rubber condom-type thingy so it won't mess with the vacuum system while not in use.
What we need to do is get a hose attached to it so you can suck out the seafoam from whereever. But wait! what if you, like me, don't have a hose? Improve time:


I took a regular 16oz bottle of water (aquafina i think?) and cut off the bottom half. then, I started to poke a little hole into it. MAKE SURE you dont jam a huge hole in it, we'll let the nipple do that. We just want to get one started, so it will form a halfway decent seal around the nipple. Once you have your little starter hole, poke it onto the nipple to enlarge the hole enough to stand there by itself. Take care not to constrict the TB's path of movement, you'll need it later. Duct tape the bottle to the manifold or w\e just for a little added support. Measure out 1/3 pint of the solution, and, with the engine warmed up and running, SLOWLY pour it into your littke makeshift can. It took me about 3 to 5 minutes to get all of it in without stalling the engine. If you end up stalling it, turn it back on and get back to work. Once you finish it up, turn the engine off and let it sit for 5 to 10 minutes. Then turn it on and give it a few good revs and let it idle for a minute or two.

Next step is to add it to the crank case, by way of the oil system.


Pretty straight forward. With the engine off, add 1/3 to 1/2 pint of seafoam into the oil system through the oil filler thing on top of the engine block. Reseal it, and let it sit for 5 minutes. Turn the engine on, might be a bit harder to turn over but it'll start. This is when you'll see some smoke come out of your exhaust. I didn't get too much, and if you don't too don't feel bad it just ment your engine was clean. I've heard some people say that they can make their entire neighboorhood disappear, not sure if that is true or not...
IMPORTANT: for the oil system, you will need to change your oil about 500 miles after using seafoam. REMEBER THAT.

Finally, the gas system. This is by far the easiest, you just pour .5 to 1 pint into the gas tank - I didnt even use a funnel, just got out a measuring cup and poured it down. If your tank is close to empty when you do this, make sure you fill it up a bit. If you have about half of the bars you should be fine.
Hope that helps everyone!

NIce write up! I would comment tho that using a vacume hose is far more simple than your 2l bottle bottom method, tho I'm sure McGyver would be proud. :thumbup:

BTW, I copyed this to the install guide submission section, hopefully larry will add it to the install guides soon.

very nice write up indeed..even though i didn't uses that nipple coming out of the IM..i use the vaccum hose that's on top of the TB, the one coming out of the IM..if u don't have a small hose u could use the stock small hose from ur aibox..assuming u still have ur stock air box..the hose that used to connect to that nipple is wat i meant..

I just used the vacuum hose, engine just slurped it up. Had my wife rev the engine from the accelerator pedal so it would not die on me while I did it. And yes, someone on the forum mentioned it being "destroyer escort" quality in the amount of smoke produced. In my case every time I would go near the redline it looked like the Japanese fleet was roaming the backstreets of Tucson.
Your idea though for the bottle is clever :)

i always wonder if there is any benefit to using seafoam in your crankcase(oil) than using something that is meant to clean the engine, such as amsoil engine flush https://www.amsoil.com/storefront/aef.aspx. after i bought a used engine that was sitting around a garage for 2 years, there must have been a lot of crap in there. someone recommended me amsoil engine flush and after using it i didn't tell a difference at all, and my engine still ran like crap. i'm gonna try running it with seafoam and see if that helps anything at all.

Hey Do I have to do an oilchange first before putting seafoam on the oil system? Can I do seafoam in using the used oil in the oil system and then do an oilchange after 500 miles?

^^i did mine b4 i change my oil..i read somewhere that if u put it in the crankcase, run ur engine for 100miles not 500miles..so plan ur oil change after 100miles after u use seafoam..that's wat i did..but my result were of nothing.. no smoke, nothing..i guess my engine are clean..

Putting it in on old oil should be fine, the important part is that you change your oil before a maximum of 1000 miles.

nice writeup.

I like your ghetto rigged bottle too, that's a classic.

And to add to what celica402gts was saying, always make sure you put seafoam in the oil 100-500 miles BEFORE you change your oil. Doing it the other way around isn't good for your motor having the seafoam in there that long.

I sea foamed my 125k-mile GT-S for the first time ever this afternoon. It only smoked when I hit lift ~6200. The smoking stopped after a few runs. I was suprised that there was not more, as when I foamed my 45K mile CR-V, it looked like 4th of July in my court.

I hope the local partsource gets this stuff into Canada soon!!! HAHA.

How long should you wait to seafoam a new engine?

It really doesn't matter however the can indicates that for 'optimum' performance you should use it every 5000 miles or so. So i suppose after your first 5000 miles? I wouldn't think that it is too necassary but for 6 bucks I guess you can't go wrong (unless it somehow damages your o2 sensors which has happened before when used improperly)

Great write up, in my case for the GT i used a mcGuyver straw, and it worked perfectly, and in regards to the smoke, I couldn't believe how much smoke my car was blowing out, I had light white smoke for a couple of days after that, but its improved my gas mileage, by a whole lot... thanks for the discovery homeworld.
