Seafoam 4.7 V8

[klennop]

If you didn't see any smoke, then you put it in the wrong hose, especially with 90K on it. Even the seafoam burning off should have gave you some white smoke. I have never had it where there was no smoke.

I used the hose in the big foam covered hose in the front, not the one you used.

 

[Sonicpilz]

Yeah but they are both vacuum hoses right? Also both seem to be generally going to the same place too. I mean is the extra 1.5 inch towards the front of the throttle body gonna make 100% difference?

I have another can of the stuff but IDK if I should try it again right away. I bought 2 to do my wife's Maxima but havent got around to it.

Yeah you should have at least had a little smoke, I'm not sure what you did...

Also depending how much of the seafoam you put in it stays in the fuel for a few tanks.

 

[Sonicpilz]

I used 1 can. Half of it in the vac hose I circled, half of it in the gas tank. All it did was idle down but only while I poured it in, maybe 10 seconds, after than it ran 100% normal and has been for about 2 weeks now. No change, no smoke. Dunno

Did u use the kind with the intake hose you slip under your throttle body intake and run for half the can?

This kind always works well for me.

 

[Zuke]

I am guessing that intake hose is not connected to the main intake. You should have gotten some smoke. The idle dropped because the vacuum was plugged with the seafoam. Use the hose off the PVC. Pull the hose off the PVC and stick the hose in the can with the engine running.

You won't mess these spark plugs up but these ****ty bosch ones did on my BMW. :redbrick:

Can someone who successfully ran Seafoam through their vacuum line on a 4.7 V8 just take a picture of what hose it was with the hose clearly marked in the photo, please?

I would like to seafoam this weekend. All the photos in these threads seem to be from the people asking where rather than the people showing where.


EDIT: Nevermind - finally found someone who posted a pic. http://www.toyota-4runner.org/4th-gen-t4rs/88205-seafoamd-4runner-6.html

Pull this hose and feed it seafoam.

u mean the hose that red stick is pointed to?

 

[danny]

Yes, that's the one I used. It had great vacuum suction. Poured over half a can of Seafoam in it, let it sit for 15mins, then revved it up. Didn't have as much smoke as I thought I would - especially compared to all the videos I've seen of others seafoaming their vehicles. I must have had a fairly clean engine at 100k. Even so, it's noticeable in throttle and helping eliminate that "guttural" sound and feel in the fuel line when pressing the accelerator.

I'd recommend.

ive seen seafoam work and not work in the past... i personally have never tried it, so I dont have a serious opinion on the matter. However, I would also suspect that if one would need to use seafoam at roughly the 100k mark, I would also look into replacing the sparkplugs- or at least taking a look at them; as well as having the fuel injectors cleaned or replaced if needed.

its on my list of things to do anyways..... anyone else use the seafoam with any results? im just curious too

 

[chaz]

theres been a bunch of threads on it over the years on different gens., just do a search for "seafoam"

Ok I have run seafoam in many vehicles but all of them had brake booster vac lines to run it through the intake. What is the best intake line to run it through on the 4R V8?

I did this a month or so back. I used the little nozzle with the black cap on it. see the picture. Pop off the cap, attach a hose to it and it will slurp up the seafoam. Someone will have to rev your engine, mine cut out a couple times but it was ok.
I got a ton of white smoke for about 10 minutes.
Also did a full can in my gas tank and some in my oil about 30 miles before a change.

My 4r had about 95k miles then

Hope this helps

saw this license plate on a little sentra two days ago, sorry for the bad pic quality, it's a zoom cropshot from a cam phone original..

 

[lonesouth]

Did it last night. Found it easiest to disconnect this hose. Let it slurp it up, turn off engine, let sit for 5 minutes. Crank and rev 2k-4k till most of the smoke is gone. Spirited 15 minute drive afterward.

 

[4wordSOUL]

Running through a treatment as we speak...put it in this hose

A fair amount of smoke the first 60 seconds. Put it in my crankcase, PVC and gas. I'll update you about improvements after I change the oil.

Might just be me, but I won't seafoam the oil. The vac lines, yes, but not the oil.

Is it truly safe in the oil to flush before change?

I have done it to almost all the used cars I have bought and never had an issue. Just add it about 100-200 miles before you change it. I did leave it in there for about 1000 miles on an old accord and it didn't give me any issues.

Thx. I probably still won't do it, just because I'm a wuss... lol, but to explain why, I had a 91 Accord about 5 yrs ago (just out of college), and to be fair, it had over 150k on the clock and had sat awhile at one point. But anyway, that thing didn't smoke or leak any oil, that is until I decided 'hey, it'd be nice to clean this baby and make it last a lot longer' and bought some BS oil flush stuff that you add and then just let your car idle for like 10 min.

I followed the directions perfectly and then changed the oil. Next thing (like within a week), it started leaking oil baaad under the timing cover all over the belt, and at cold startup, it would blow out this thick, heavy smoke cloud that would not dissapate. A mean, the cloud was nuts! So I drove it for like a week like that and then basically got rid of it and bought my 01 Accord.

Now, this was not Seafoam, and I forget the brand, but I learned (right or wrong) not to use any flushing additives, for my own fear maybe.

Now I just make sure to keep nice short oil change intervals. Remember, oils these days have additives in them adready that should be sufficient in my opinion.

But that's just my 'opinion' and no facts/data. I could be innaccurate.
