The white smoke is not the carbon burning off, it's the seafoam burning off that you just dumped in the engine. How the hell would "carbon burning" emit white smoke?

Don't think I'm picking on you because I'm not. Not really anyway. I see people say that all the time. Just what do people think is in carbon anyway?

 

Yeah when I did it through the brake booster line, it blew white smoke for a few minutes at least, and then the white smoke cleared and it started giving off this rank blue smoke. I took it for a drive and it took about a mile or so of driving to get the blue smoke to stop and then everything was fine. I have a feeling that was the gunk/carbon.

 

I put it through the brake booster on my 22RE. It had a pretty new head and I had just rebuild it. If anything, the smoke came from the dirty intake manifold (I have since cleaned it by hand). I did not notice any improvement. I put some in the fuel as well. No improvement here either. I don't think that means Seafoam is useless, but instead my engine was clean.

 

i have used seafoam in 2 of my vehicles. the first one, shortly after all 4 injectors failed. i thought it was coincidence, so i tried it again on my '99 4runner, shortly after my headgasket failed. im not saying seafoam did infact cause this, im just saying i will never use seafoam ever again

 

ovrrdrive, it's just what I've heard over the last couple years. Friend of mine used it and it didn't smoke so I assumed a clean motor, thus no carbon to burn off.

alexe, you could've done it wrong?

 

I put a half can in the oil about 100 miles before every change. About 4 changes ago I noticed little bit of sludge if I looked inside the crankcase, near the oil cap opening. Now it's very clean. Love that stuff. Not my vehicle, but a comparison between clean/sludged crankcase:

Scary sight.

 

Well might as well post it up once more my 22re sounds alot better now then it did then

thanks martha...

 

I was told if you haven't used seafoam before on an older moter, it would be best to gradually introduce seafoam to the 4runner. Run it in the gas a few times, and then in time run it through the intake. B/C if not, those carbon buildups could just chunk off and lead to some problems, such as a need to change your plugs and your o2 sensors. It was suggested that I add two to three cans of it into half a tank and then drive w/it until I need to fill it up. Do this a few times and then add it to my intake. Crankcase.....hopefully regular oil changes prevent the need for me to do this.

 

wow i re-found this forum right on time, you gotta love google.

Seam foam works great, Ive used it on 6 cars but only through the brake booster vacuum line. The benefits from using it through the fuel tanks are very minimal from what Ive heard - the bottle actually says it too if I'm not mistaken.

I actually wasn't aware of it giving people better fuel economy I guess i never pad attention... Maybe thats just what my truck needs, at 16.3 mpg out of a 4 banger im sure it wont hurt.

I don't know why, but I have a funny feeling that the seafoam treatment had a helping hand in blowing my headgasket. I mean it MAY just be coincidence that it blew the next day... Maybe...

 

MMMMMM Seafoam, must try.

 

There was a video on seafoam that looked like it was done by the manufacturers, anyone got the link?

 

Sorry, i am really fogged up today. anyone got pics of the entry points on a 3.slowV6? I am due for an oil change in 600 miles, but want to try it in the gas and the brake booster. maybe the slow infusion technique is best, but I will try it and try the advance the timing trick to see if i get more power and MPG.
Thanks
