Topic: To SeaFoam or not to SeaFoam, THAT is the question...

[tperkins]

Hey guys, I have done some searching and basically there is no solid train of thought.

Here are some of the things that I found, this is a pamphlet that Napa had,

I am just wondering everyone's opinions on the stuff and using it in our cars.

I have been thinking about doing it, would just be following the instructions in the pamphlet but just wondering everyone's thoughts.

I've used it on my Civic. Some people like it, some don't. I think it's a perfect way to find exhaust leaks. I'm too tired/lazy to read the pamphlet right now, but I put 1/3 in my gas tank, 1/3 into something like a brake booster (or the intake if you can) and depending on if i'm doing an oil change in the near future (i think within 500kms), 1/3 in the crank case (1/2 and 1/2 if I'm not).

I want to run it on my STi, but last time I was at Autovalue, they didn't carry it.

DO NOT USE BRAKE BOOSTER LINE IN SUBARU'S IT WILL ONLY GO TO TWO OF THE FOUR CYLINDERS WHICH IS NOT NOT NOT GOOD.

use the line coming off the BPV that is on the top mount. that will go to all four cylinders.

also i would recommend not going over 50 miles with the sea foam in your oil.

the additives in sea foam dont mix well with the additives in some oils

I have read this on IWSTi and 2.5RS (been forwarded the info from them) that it just goes to two cylinders? Where is(are) the other option(s) located?

[LilDrunkenSmurf]

Never used it on my suby, that's just what I did for the civic. It had a different intake mani.

I would say maybe use the line off the BPV if you can? If you can manage it, maybe straight into the intercooler? Then you can clean that out as well? Or if you have time, remove your intercooler, and pipe it straight into the throttle body. Idle it till it's all in there, kill it, put it all together, and start it all back up?

I just did the Seafoam treatment on my Xterra 2 weeks ago. I did the 1/3 treatment, I haven't driven it much after I did it though so I can't say how much difference it is. But from reading on the Xterra forums it has done wonders for some people. I'm not sure how it would be on Subies.

[Kingsoup]

I did 1/3 can on my 1990 Celica with 280,000kms, it worked really well, I think it cleared a lot of carbon out of the PCV, noticible difference in smoothness and acceleration, definatly not just snake oil.

Quick Question,


Just would like to ask before I do, as seen in the picture I am assuming that I want to use the "red" one (the one drawn with red)?. That would be my assumption, just want to double check it looks like it goes right into the intake manifold, where as the yellow one (I would have to be spooling to work?) that then goes through the Top Mount Intercooler through the throttle body and into the intake manifold, amiright?

Just to reiterate, use the red one?

(yes t does bother me the red paint is chipping off)

[tperkins]

OK, upon further inspection I realized that I am an idiot, the yellow arrows right by the BPV are backward, silly of me. (MY first hint was the two big arrows on the valve pointing in the opposite direction.)

[Zac]

I used it on my old legacy, I just poored the whole can in the gas tank and enjoyed white smoke all week

[SLO GTR]

The previous owner did it on my car, he said he noticed some good things from it, there is a thread somewhere on here.

He used the little vac line that runs to the bpv.

[Jarrod]

A little off topic but now I'm kind of curious about how the BPV works.
The vacuum line is to pull the BPV open when there is no pressure/boost right?  So does that mean while there is no positive pressure, the BPV is always open?  And positive pressure in the manifold kind of pushes the valve closed.

So if one were to pull off the top hose as indicated in red, you just need to kind of plug it up and shove this seafoam in it as it will be sucking in air?  Will the BPV be open or closed?

[SLO GTR]

You don't need to plug it, you simply remove it, and dump the sea foam in there. I am not sure whether or not the bpv will be open or closed though.

hmmm did you want those of us who have never used it but are interested in the thread to vote?

Just put the seafoam into a glass and suck it up like a straw works.

People vote in elections without knowing much about the candidates all the time, and I am sure everyone has heard something about it, lol just kidding I am only trying to cover my own assay.

[Kilroy]

I'll give Seafoam a big thumbs up. I've used it on a 1998 Acura RL (huuuuge clouds of smoke) and a 1988 Chevy K2500 4x4 (very little smoke). In both cases it helped considerably and I keep a couple of cans in my garage at all times. NAPA carries it, but it is about $13 per can. If you go down to the U.S., pick up a case of it. They sell for $4-$6 per can there.

I used it in a 1992 maxda 323, intake and gas tank, none in the oil.  throttle response improved, better drivability, and millage!

Brother inlaw used it on early 90's mazda pickup, oil started leaking out rear main seal.  But it improved idle, and response.  I would say it's good stuff, but be careful on old engines using it in the oil as it might loosen up old deposits that were sealing little cracks!

But i wouldn't hesitate to use it in the engine intake and gas tank even on an old engine.

Good to know, been thinking about doing this in my gfs truck 97 GMC 2500 with a 5.7l and was worried about this.  If I do it then just intake and gas.  I maybe want to wait till like 1/4 tank of gas though. 120 liters is a lot of gas to burn through.
