Sea foam (NOT a dumb question)

[mixxamike]

I'm just slightly confused as to the proper order of the steps of using Seafoam. I found this with my search

I bought 3 bottles ($6.00 each) for my Nissan. Pour 1 bottle into your valve cover through the oil filler cap and 1 bottle into the near empty gas tank (add 10 gallons of gas). Drive the car normally until you have used up all of the gas (then refuel your car as normal). Change your oil and oil filter. At this point your injectors and valves should be clean (normal injector cleaners purchased at autoparts stores really don't do anything).

The next step involves disconnecting the break booster hose at the break booster. Insert a funnel into the end of the hose. Turn on the car and let idle. Slowly pour 1/3 of the 3rd bottle of SEAFOAM into the funnel with the car idling (pour very slowly, the car will run very rough while you do this). After doing this, turn the car off. Wait for 15 min. Turn the car back on and let idle. Black smoke will billow from your tail pipe for several minutes depending on how much carbon is in your engine (20 min. in my case). I actually did this last step 3 times (used the entire bottle).


My question...

After I put the seafoam in the crankcase, how long do I drive around like this? From the info i found above, it sounds like the length of time it takes me to use one tank of gas. What are your opinions/what have you done? Also, the above info makes it sound like you shoud put the seafoam in your brake booster vac line AFTER you change your oil....wouldn't it make more sense to do this BEFORE you change your oil so as to not contaminate a fresh pan of oil/filter?




Thanks!

do not drive around with sea foam in your oil it causes the oil to thin out. its ok though to run it through your brakebooster line and your gas tank.just when you use it in your oil just put it in there and let teh car idle about 20-30 mins and then change oil

[morpheus8486]

A can of seafoam for each thing? Hmmm...think one can of seafoam split into three parts will do the trick? Cuz that's all I got.

[Bryants95240sx]

yeah one can will do it

[nightwalker]

yep, just did mine the other day. 1/3 here, 1/3 there, another 1/3 there. Talked to some old skool V8 heads about it, those guys swear by it.

[Toahk]

Ah did that long time ago, mucho black smoke! Nightwalker, you get my email?

[sleep]

I never heard of doing this before... This sounds interesting. Which Vac line is the 3rd step?

[ledzeppelin240]

Deluzional: Did you even read this any of this?
It clearly states which line to pour it into...

[Ghettokracker71]

Black smoke? WTF? I've done it in 3 diff. nissans (2 max SE's and s13 w/ka) as well as some others (5.0 bronco,22RE,poshonda) and its always came out as white smoke? Hmm...

[AlligatorBling]

yeah i had white smoke too.... and a lot of it. enough to shoot an 80s hair band video.... i just did a treatment on my yamaha 350 warrior fourwheeler too.. ran it though the carb, some in the gas tank... that stuff also stabilizes fuel! and the crank case... im gonna do another treatment on my car at the end of the month with my oil change.

[Ghettokracker71]

Lol yeah I use it in my lawnmower and weedeator,blower...everything man!

[FallbrookS13]

im going to do this on the weekend. thanks for the info guys.

Yeah yeah yeah the misspelling of 'brake' threw me off. Plus i never knew the brake booster had a vac line...
:loco:

[ledzeppelin240]

Hahaha no problem...brake, break I hate when people talk about vehicle brakes and spell it break...

[morpheus8486]

I hate it when people just don't know how to spell. It bothers me. Anyways, how often do you guys use this stuff?

[nightwalker]

I wouldn't do it too much. Only when you purchase a new to you, used car. You should know how to keep it clean afterwards. Plus I wouldn't do it if your car burns a lot of oil.

[mixxamike]

^well hey, that wasn't me who spelled "brake" incorrectly. :P

anyway...i just did the whole seafoam treatment, and after running the stuff through the BRAKE booster line...there was hardly any smoke. Nothing like the billowing clouds all of you speak of anyway. I guess that just means my 73k engine wasn't very dirty?

[Ghettokracker71]

I did it on a 1997 Maxima SE with 50K and to quote the guy I did it with (my uncle,who reccomended it) "she was smoking like a freight train"

That thing left a ******ing trail that litterally shut traffic down behind us b/c they could not see through it.....LOL it was fun as hell b/c we were in this newer body style 4 door,waxed up so it was really pretty smoking like all hell.

I didn't see any smoke come out of my car until I reved the engine a bit. You might want to do that and see if anything happens. If not, who knows where you poured the seafoam.

[mixxamike]

tucker, i poured it right into the brake booster vacume line and the engine sucked it right up. The was "more" smoke when i reved the engine, but not like a freight train.

[Ghettokracker71]

How much did you use? Was some other kind of similar product recently ran in the car?

[mixxamike]

i used about 1/4 can, i'll put a bit more in tonight and give it a whirl.

[d r i f t swift]

so where am i supposed to get this stuff

[mixxamike]

Napa...i work there and we sell tons of it.

[FallbrookS13]

just did this and tons of white smoke. fun stuff.

[Monooxide]

Not even sure wth the brake booster is? Maybe im just using a diff name but...where the hell is it? So should I use it until it stalls out or just use it until 1/3 is gone then shut engine off?

[sw20>>s14]

its available at autozone now. anyways, you might want to replace your spark plugs and o2 sensor (so ive heard) after a treatment. supposedly the carbon gets on the plug tips and the o2 sensor. did it on my friend's sw20 and my whole block was filled with white smoke...neighbors thought his car was gonna explode or something...

[kandyflip445]

The brake booster is the big black thing behind the master cylinder. It's on the driver side of the engine bay on the firewall.

[michael1284]

Just to get this straight...so we DONT need to add 10 gallons and run through the whole tank of gas before we change the oil? Instead, put it in the gas tank and idle for 20-30 min?? :loco:

Kinda yes, but not really. It's more like you have 3 options.

1) Pour into gas tank when it's close to being empty and fill up gas as usual.

2) Pour into the oil crankcase before you do ur oil change. Idle for a few minutes, then change the oil as you normally would.

3)Pour into brake booster line and let the car idle until the white smoke disappears. The car will smoke for a bit so just be patient. It will seem that the car is choking and wanting to die but just add gradually to the point where it doesn't die completely. When the smoke is gone your done. Change the spark plugs and o2 sensor and thats it.

Basically each one of those 3 are independent of each other. You only have to do one of the 3. However if you were to do it, it woudl be a good idea to do all 3 since it cleans the car more. If you don't want to do all 3, option 3 is the most noticeable difference that I've done myself. The car idles smoother and helps clean a lot since all the white smoke is all the build up inside your combustion chamber.

[sr240mike]

Isn't it, pour into brake booster with car running, turn off car, let sit for 10 minutes, then let it idle till it burns off?

[blu808]

Boobyboy and i did this to our cars the other day.
Works really well, im doing it to my truck today just to see how much smoke it will make.

1. pour 1/3 into the oil
2. pour 1/3 into the gas tank
3. pour 1/3 into the vacume system, pcv/ brake booster

if you put it in the oil make sure you change the oil before you drive on it. just let it idle for 10-15mins or so.

[Irving18m]

OK im going to be brave and ask where the brake booster line is on my 90 s13 240. Thanks guys!

[SimpleSexy180]

i think there talking about that rubber hose that ends up going to the eccs? am i right?

[AlligatorBling]

read the back of the can

[Irving18m]

read the back of the can
If thats directed at me, im doubting that on the back of the can it says where the brake booster is on the 240sx! :-/

[AlligatorBling]

no, i wasnt talking to you. but now i am. you might be able to find that in a service manual, or you could be clever and say hmmm break, whats under my hood to do with breaks. OHhhh, i got it... the master cylinder... ok hmmmm we got that part, now lets be real clever and think about the line itself, where would it be, probably connected to the part under the hood that has to do with the breaks. if sea foam goes into the motor, the line must run somewhere to where it goes into the motor right? i bet if you go snoop around under you hood you might be able to figure it out.

[Irving18m]

Disregard my dumb :newbie: question! Im at work and 2 and 2 was not clicking together in my head! I will be trying the Seafoam this weekend! :bigok:

[NismoDan]

I SeaFoam'ed my KA twice (via brake booster) and never got any smoke...at all.
Maybe a new cat stops the stuff from getting out?

[blu808]

The cat will not stop smoke. Unless you just got done doing the 24hrs of lemans and your cat is around 10 billion degrees. Anyways.

The brake booster line is pretty easy to locate.
Take a look at your brake master cyl. This is the thing that you put brake fluid into. You will see mounted directly behind the master cyl, and black big roundish metal looking thing. This is the brake vacume booster.
To the left of the booster you will see a rubber hose coming out of it. Its about .5 inches in diameter with a residule pressure valve or two. This is the brake booster vacume line. Undo the factory c clamp with pliers so you dont cut yourself, then rotate the tube to break the seal. You should now be able to disconnect the hose from the booster. Now fill up a small cup, or spray can top with seafoam, and start the car.

Your car will barely idle, because of the vacume leak, so it is best to have a friend plug the line with a finger. Then with the car at about 2k rpm, dip the tube into the liquid. Dont put it in all at once or your car will stall, just let it suck it up, until the motor stumbles, then let it revive itself, repeat the process until all liquid is consumed. Place the line back on the booster and c clamp it. Keep in mind if this line comes off your brakes dont work, so make sure to clamp it. Wait till you see the smoke, then turn the motor off. let it sit for 10 mins then turn it back on and let it run until the smoke goes away.

good luck

all i gotta say is, pour too much of that shit and " HYDRO LOCK" :) bye bye motor.. anyhow i planned on using it, bu ti was instructed to use an eye droper in the vac line to enshure slow drippage instead of pouring it in with the funnel.

brandon

[sw20>>s14]

put it in a cup and slurps away...blu808, good to see your back, got any more tires?

[blu808]

ha ha. thanks. bro. I can allways get some tires.

Anyways. Be carefull to pour it in as slow as possible. Unless you want to hydrolock your motor. If that is the case i reccomend a cheap way of hydrolocking. such as revving your motor to 7k rpm and shooting a fire hose into the intake

[Drunk Bastard]

this is great, luke comes back and every single post has been informative!
luke, do you have a deal goin on with the mods about no BS posting?

sw20, what size(s) are you looking for? pm me with details. i might be able to help you out.

They are just giving me a second chance.

and im not allowed to post dumb stuff.

[tastyratz]

i just ran this stuff through my oil on my car and my crank case. I got tons of white smoke which is normal but I dont know if it was white or gray since i did it at night. white smoke is when you get when you burn the seafoam at the fast enough rate, if you dont see it you put it in too slow. black/gray smoke is when you get carbon and crap buildup coming out. I never did it in my car and ran a compression test on my motor before I ran it. my car is a sohc with 77k miles. I put almost half a can in the oil and drove for almost a week with the stuff in there but I always kept it under 3k rpm and I use mobil 1. When it came time to drain my oil it came out like thick black nasty sludge I have never seen before, and this seemed like a very clean motor. After the oil stopped dripping I flushed a quart of mobil 1 I had through it to drain down the crankcase and out the oil. It was completely black and nasty by the time it got out of my oilpan which is insane. my car runs MUCH smoother now, idles nice, feels like I have a bit more power and its like a brand new motor should feel like! like it was said before, if your not burning oil then this stuff is a miracle!


*edit* btw how many of you ran it in your gas? I know we have that problem with the injector o-rings going with fuel additives so I didnt put any of this stuff in it. is this fine with those?
