just wondering what the consensus was amongst those of you that have experience using it. I have a 95 camry 5sfe and need to clean the throttle body apparent from the bad idle - figure i clean it out first before anything else.

anyways, they sell seafoam at the local walmart... should i dare add it to my crankcase and or gas tank?

Its perfectly fine in the gas tank. The crankcase I woudlent recommened since it can cause more probelsm then it can fix.

It isnt going to clean your throttle body though. To clean your throlle body yo uneeed some carb cleaner and take of the air intake hose and spray it down and scrub it.

However sucking half a can through the pcv valve hose wouldent be that big really any risk. Just do it slowly and dont let the engine die.

i mentioned the idea to my dad and he said that adding it to the crankcase and or gas tank is a bad idea. i believe him when it comes to the crankcase but am tempted to try it in my gas tank.. is it even worth it?

ive read of ppl having smoke coming out from their exhausts for like a minute from all the carbon it expels.. is that from adding it to the gas tank?

oh and i realized that its not for cleaning my TB.. any reccomendations on brands while we are here>

Gumout or really even the walmart brand will work. Just scrub it good and use the showle can if you have to. Make sure you spray it far down in their with the butterfly valve open.

The smoking from suckign it into the intake can get a lil obnoxious. Try doing it at night so the neighbors dont throw a fit.

same here. it really is a miracle do it all. and yes, you can clean the TB with it. search TN for more threads on it and youtube for vids. :thumbsup:

I love Seafoam.

Yes it will produce white smoke, the more smoke the dirtier your engine. I don't think you'll notice any smoke just from putting it in your gas tank though, it gets too diluted and its too slow of a burn.

Put it through your PCV valve like I do... well... I got a LOT of smoke. And until this thread I hadn't heard anyone say that it is bad to let your engine die while letting it get sucked into your PCV valve. In fact I heard that it was okay if it stalls.

It won't hurt anything if you feed it into your engine through an intake, or in your gas tank.

Some people put it into the oil but this can cause serious problems and should ONLY be done shortly before an oil change.

I let about half a can get sucked into the PCV valve, and then turn the car off (if it doesnt stall first) and let it sit for 15 or 20 minutes before turning my car back on.

I ran sea foam through the brake booster, crank case, and gas tank simultaneously. Not much smoke at all, engine did stall once while sucking via the brake booster, no biggie. I drove 50 miles, did an oil change to get it out of my crank case. Car felt the same, maybe a nicer idle. & I also cleaned the TB with it & a tooth brush.

Mind you, I didnt think it would be much of a problem in the crank case, as the car only had about 63,000 miles on the engine.

i did the same thing booster line tank and crank case.
wasnt much smoke.. if i remember there was maybe about a mins and 45 seconds of smoke..

i did a oil change a 100mile after added to crank

it ran a lot smoooother.

before the seafoam i got 200 mile to a tank (hard/slow acceleration)
after seafoam i get 280 to 300mile a tank

After reading this thread and looking at previous threads regarding seafoam, I think I'd like to try it.

Although I have a few questions...

Mind you, I didnt think it would be much of a problem in the crank case, as the car only had about 63,000 miles on the engine.
(1) Does that mean it wouldn't be a good idea for higher mileage cars?

I was thinking about putting some in the gas tank and trying the PCV valve thing.

I am currently getting codes P0401 P0440 P0441 P0446 P0770 and P0420 as the most recent. (no need to post descriptions of the codes, I already know what they are.)

(2) Could using seafoam help any of the problems related to these codes, or could it actually worsen any of them?

After reading a few threads regarding EGR valve removal/cleaning, I was also going to give that a try along with seafoam, and hopefully that would clear up some of those codes.

1) basically, the seafoam could knock some sludge or other junk loose inside the engine and throw it somewhere where it could do some damage. BUT... i've ran seafoam in my crank case 120+miles before an oil change. I'm just over 170,000 miles. :thumbsup:

2) If the 400 series of codes are emissions codes (if i'm remebering correctly... it's 6:30am here) then yes, you might get a few of the codes to clear. The PCV & EGR valves would definitly be a few good things to clean. :)

MY Cam 97 has 118k on now.

I Use techron -fuel system cleaner
Auto-RX- for oil system cleaning
SeaFoam- through brake booster line and toothbrush throttle body

Did it help? I feel like car overall has smoother idle and after sea foam it accelerates little better. Just please make sure instructions beffore using any of those products for the best results.

I'm not sure what those codes mean but clean egr and clean or replace pcv valve.

I'm mainly wondering if using Seafoam would be bad on such a clogged up emissions system, or could it possibly help clean it out?

For example, someone reported getting a P0420 after using Seafoam through the PCV. Since my car is *already* getting a P0420, is it still alright to use it?
 
#17 ·
When I was replacing my pcv. I saw there was a lot of dirt in the old valve. Valve is like 6$ and grommet is like 2$ Just replace it. If you see that there is no wet areas around the grommet just change the valve. I had to replace both. it was pain to take the grommet out , at some point it fell inside the block, likely I was able to take it out. To cap the story I used 87 to 94 Camry grommet because nobody had 97. Everything works fine :p

Can somebody please edit the picture below and point out specifically which hose and which end of that hose to remove and feed the See Foam Deep Creep through?

In this thread it was mentioned to put it through the PCV valve. In another thread a guy put it through a hose at the VSV for EVAP.

:confused:

Take a half can of regular seafoam. Take your pcv valve and unhook it from the hose. Take the bare end of the hose and turn the car on. Slowly suck the seafoam in. Try to not let the car stall, after it sucks it all in turn car of and let sit for 15 min.

Then turn on a rev it a bit (3-5 min to let alot of the smoke get out) and then drive it pretty hard for 10 min or so.

Just replace your pcv valve, no point in cleaning a 4$ part.

Ok, so I did a Sea Foaming tonight. First I let the brake booster hose suck in about a third pint of Sea Foam. I did it slowly so the car did not stall. One weird thing that happened... after revving the car for a bit, I shut it off... removed the key, and the engine was still running. I think I created a monster! ...eventually it stalled.

I also poured maybe a quarter pint into the gas tank. I went for a drive on the highway to let it clear out.

Later in the night, I was going to spray some Deep Creep into the PCV Valve. Took some effort to remove the damn hose, but eventually I got it off after some cracking. I was actually spraying the stuff right into the PCV Valve going to the cylinder head cover. I think I was supposed to spray it into the hose leading to the intake manifold? 'cause the air flows the other direction. So that obviously didn't work, and I didn't realize why it wasn't working 'till I got back home. So I will try it tomorrow. In the process, I managed to crack up that little hose a bit, so I'll have to replace that too when I replace the PCV Valve.

Then I took a swig of some Sea Foam and swished it around my mouth. I hear it cleans up the liver. Just beware the smoke that will shoot out of your ass, as it can get pretty violent. :clap:

lmfao! :chug: im glad that it didnt kill your Camry with over 333k. how was the fumes out of your car? how long did it last? im assuming you have never used seafoam before in this car.

I am considering adding it to my oil, through the brake booster, and a little in my gas tank after learning that the reason why ppl have problems with seafoam is because it works too well. ive read that for some people it cleans up the sludge which is actually causing compression in their cylinders. I think mine should be fine at 166k w.full synthetic used ever since day 1.

i did the same thing booster line tank and crank case.
wasnt much smoke.. if i remember there was maybe about a mins and 45 seconds of smoke..

i did a oil change a 100mile after added to crank

it ran a lot smoooother.

before the seafoam i got 200 mile to a tank (hard/slow acceleration)
after seafoam i get 280 to 300mile a tank
that kind of an increase in mileage is awesome! i want to try out this seafoam stuff even more now. I might wait a week or two, before my next oil change and try it in my crankcase

removed the key, and the engine was still running
I did seafoam couple of times already. One time engine was still on after I turned the car off. Don't worry about it. I must say smoke lasted for good 15 mins when I did it for the first time, Now smoke lasts for about 5 minutes. There is some residue inside the pipes where spark plugs are. This might cause trouble for some if not cleaned.

This is my first post out here so i am a 'newborn' to the site.
I was looking into fuel injection cleaners, throttle plate and whatever else that was recommended when i got my car tuned up. I was looking into the Sea Foam and saw some mixed reviews but mainly good ones.
Ok this is my question. i just got my oil changed so i cant put it in my crankshaft/oil. so should i just put it in my gas tank and PCV valve line or brake booster? i did notice a change in my gas mileage and rough idling.
 
#33 ·
i hear that adding it to your gas tank won't help all to much but running it through either your pcv valve or brake booster will yield most of the benefits that seafoam offers. good luck cleaning up your car :thumbsup:
 
#35 ·
Also depending on when you changed the spark plugs (if they are new, put old ones back on) seafoam can foul the spark plugs. I have not personally seen it happen but some on the forum have.

And there is no need to use up a half bottle of seafoam, 1/3 bottle will do.

Slowly let it suck up the brake booster line with out stalling the car out. Then let turn off the car and let it sit for 15-20mins and restart car. Don't rev the car right away, let it idle for 10-15 mins or until the smoke has subsided a bit and take it for a spin on the freeway or somewhere where the speed limit is a bit higher around 40-50mph. That should clean it out good.

Slimgoodie which camry do you have? 6v or 4 and which year? I have family in SC Columbia will be visiting them for this thanksgiving. Anyway I used seafoam three times with in three weeks , bad for the car? Maybe but everything works fine. I took plugs out and I saw those rubber adapters that go on top of the plug had white resideue I just wiped it off. It seems like there is white powder around the sparks ,on the sides of the tupe so it doesn't touch the spark. That should be vacuumed out. One sea foam cleaning won't make anything to your plugs. Use 1/3 of the bottle and you will be golden.

i did only the tooth brush cleaning on the TB, but the results are absolutely obvious after a week's driving. From the tank half way full, i have like 33% on the gas gauge still left after a week and 3 days of daily use. I also drive with tiny bit of lead foot. I'm getting at max 30mpg and a min of 21mpg. I used to get a max of 25mpg. I'll do a real mpg experiment sometime to prove my statement.
