does any vacuum hose do for the sea foam? Can i use the one connected to the CAI or do i have to use the one right behind the throttle body on the top right next to some sensors? if looking towards the front of the car?95maxima.....

 

Use the brake booster hose and let it suck in the SeaFoam a little bit at a time. Then turn off your car and let it sit for 30 mins or so and then turn on your car and watch it smoke Going to do this today or tomorrow.

Just after my throttle body there is a small vacuum hose on the intake manifold, though its not on my dads auto 96? Well this is the one I used, you can see it in this picture. If you look on top of the manifold where the TB is you can see it. The fitting is pointing to the brake booster. The hose comes off the fitting and travels around the opening of the TB. Well if you have it use it because it gets all the cylenders and cleans all of the intake manifold.

 

hmm well if u can get a closer pic and highlight the part it would be very much easier to see and i would appreciate it thanks.WEll i have an 95 adn your dad has a 96 so that means i wont have it on mine????

 

Just did this a few hours ago and the white smoke was crazy. One of my neighbors got scared and asked me if I needed help with something The white smoke clouded everything behind my car and there was some smoke from the engine bay too (exhaust leak somewhere?).


That's the brake booster hose in yellow. Disconnect it from the black box thing (the place where I put the red circle). After you disconnect it, turn on the car and pour some SeaFoam in a cup and let it suck it in a little by little. Then turn off your car and wait like 20-30 mins. Then turn it back on and rev it a few times and watch the rear of the car get clouded with white smoke Then take a drive until it stops (mine took like 10 mins to stop).

 

oh thanks very much ill do this later on today.Cant wait to smoke out hehe.

 

How much did you pour into a cup?

I'd say I poured a little less than half a cup and it smoked a little nothing really major like you guys are saying. I'm gonna buy some more, since that was an old can I finished off today.

 

well it worked out good smoked out my neighborhood today everyone that i had fked up my engine haha..

 

I used a Dannon fruit yogurt cup I poured in maybe about a centimeter high and I let that get sucked in little by little. Then I poured some more in the cup and let that get sucked in. I did that until I used up about 1/4 of the can. Turned off the car and let it sit for 20-30 mins and then turned it on and held the accelerator at like 2k RPM and watched the smoke. Then I went for a drive (it stopped smoking after like 10 mins)

 

Why are you guys using so little amount? I though you would use the whole can. Some one please explain. So if I use the brake booster my whole engien will get cleaned?

 

I used 1/4 the first time and a little more the second time. I wanted to do it in small amounts b/c I didn't want to risk messing up the engine Better safe than sorry

It should clean the whole engine

 

Why cant you use the whole can? Is it too much even if I go little by little?

 

You can, but I didn't want to risk it. I think someone did put the whole can in before and it worked out fine. I bought 2 cans and used 1 can in the gas tank and used half in the oil. Had half a can left to do this.

 

Full tank?

 

The directions say to use 1/3 to 1/2 a pint through the intake, so......that's why most people don't use a whole can. I say better to run 1/2 a pint through twice than 1 can all at once. Personally, I just dumped the other 1/2 of the can in the crankcase.

 

I just poured some more in. I poured more than half a cup in. And poured that through till about a 1/4 of a cup left. Then I let the car sit for about 10 minutes. Then poured the rest in.

It smoked a lot, but not crazy amounts like you guys are expierencing. Now if my motor doesn't have a lot of carbon in it thats GREAT, but I want to see the smoke show . I'd say as soon as I got down my driveway it pretty much stopped smoking.

I'm gonna pour the rest of the can in tomorrow, just for a thorough cleaning

 

I poured 1/2 in my crank case, and half in my gas tank... not that much smoke came out though?????? puzzled... but I am going to get another bottle and use half of it through the brake booster and the other half on another car.

 

You'll see the smoke coming out when you let it get sucked in from the brake booster hose

 

Sending it through the crankcase or fuel won't really make any smoke at all. Now the brake booster on the other hand, that's a different story .

 

is it safe to drive around with the 1/3 of seafoam in the crankcase?
i mean at least for another 1k or so till i change my oil.

And with the fual tank, do you guys doit on a near empty tank of gas?

 

Someone contacted the SeaFoam people and they said to pour half a can into the crankcase and run/drive the engine for 15-30 minutes and change the oil (to get most of the crap out). Then pour the other half of the can into the fresh oil and run it until the next oil change. Here is the thread: http://forums.maxima.org/showpost.ph...8&postcount=20

I poured the SeaFoam into a nearly empty tank so when you fill it up with gas, it'll mix better

 

Just picked some up today

*Warning: Fumes will be extreme for a short period of time*

: ) I can't wait.

Will using the brake booster hose clean the throttle body? Also, will it set off my ECU?

 

so for the vg your suppose to use the TB?

not the break booster?


which ones is that on the TB? im like which one do i pull

 

To clean the TB, use a TB cleaner Using the brake booster hose will NOT turn on the CEL so don't worry. It's just a vacuum hose so you might have to rev the engine a little to keep the car alive. I did NOT have to rev the engine since the car stayed alive by itself.

Not sure about the VG, but the brake booster hose should work for all (it says to use the PCV valve or brake booster hose right on the can) and it's brake not break

 

lol sorry my car was running so i ran here to post this up LOL. and i just used the BB

 

How are you supposed to rev the engine and look in the engine at the same time? stretch armstrong style?

 

omfg

 

hey I've heard enough from you

You better grab your party hat cause Thursday is going to be a huge event.

 

You mean you can't stretch that much?

Here's something new for you Follow these instructions: http://www.motorvate.ca/mvp.php/517 to remove everything up to the TB. Now with the car off, you see where the 2 cables are to the left of the TB?

The outside one is your cruise control cable and the inside one is your throttle cable. Now pull that half moon shaped thing up from the bottom (the thing where the 2 cables wrap around) and look inside your TB and be amazed

Put everything back and start the car. Now pull that half moon shaped thing up and be amazed again

 

Umm....well I....I knew that I was just uhh...I'm an idiot. Well at least you gave some helpful information unlike somebody else I know

 

LOL....this is too much...BTW how can you have 676 posts and not have known this? im not trying to talk smack, im just curious...

 

When I came on this site, I had just gotten into cars. And now, one year later, this is the first engine work I've ever done outside of changing oil. Hopefully one of those excuses will work

 

Picked up some Seafoam two weeks ago and used the brake booster hose. I poured about 1/3 the container into a cup and let it slowly suck out of the cup until it was done. Afterwards lots of smoke came out.

I did it again yesterday and I think even more smoke came out this time than the first time. How often should this be done? I think if your car has really high milage it might be good to do it a few times to throughly clean out the carbon.

 

I still think the FPR is the best place to go to clean everything (minus the TB of course.) You will get a ton of vaccum when you disconnect the FPR vaccum line and it will suck the crap out of that seafoam (you have to use a seperate vaccum line of course.) I floored the car (to keep it alive) and it sucked up the whole can in about 10 seconds (the cloud of smoke was ridiculously huge) and it kept smoking for a while after I drove it. After all was said and done the car ran great.

I had a bad knock sensor recently so after running rich for a while I am sure that the carbon is back. I am going to do the same thing right before I change my oil.

Maybe I can get a pic, my friend took one with his camera phone (people were coming out of their houses looking for the forrest fire and neighborhood kids were chearing.)

 

can some1 post a picture close up of the brake booster line? I have 112k miles on maxxy and its never been done. If i run it threw the booster tube does the oil need 2 be changed?

 

what is the FPR? and where is that?

 

hey guys,
just ran the a 1/2 of a can in and WOW!! i guess those 112k miles built up alot of carbon! A group of kids stopped and were like i think you have an exhaust problem! haha then cars stopped and didnt want 2 pass my house because they couldnt see past the smoke! It was hard to start but once i got it started it ran good. I hope it runs smoother once im done.

 

I went to my local mechanic today (who's serviced my car for years), and brought a can of seafoam to ask him in helping me. I tried the night before, but couldn't for the life of me get the vacuum tube to come off the engine.

He says he wouldn't recommend using the stuff, as it may cause problems down the road. I have a 112K miles on my max. He says regular oil changes and Chevron fuel system cleaner every 6 months will more than suffice.

I don't want to waste the can though, so I may place half in the crank case, and the other half into my vacuum manifold, IF i can figure out how to get the damn tube loose!

 

Push those clips inside of the red circle out then disconnect the hose at that spot. Now move the clip inside of the blue circle up then just pull up as hard as you can. It should come out. When it comes out, put everything back the way it is at the red circle. Now start your car and let the SeaFoam get sucked in from the hose where the blue circle is.

 

this should be a sticky good write up JaTaN
