Seafoam product

I posted this in a different thread, but here again:
You don't want to run the Seafoam through the brake booster line not only because of the possible supercharger rotor coating issue, but any carbon that's developed on the rotors taking up space (carbon is what the Seafoam is supposed to be removing right). Removing either from the supercharger will result in lost efficiency. Like dsmuts said, run it through the vacuum T under the nose of the supercharger. Here is some links I found:

This has been asked a few times lately so hate to say it, but might need another sticky or at least something in the writeup section. I didn't find anything there doing a search.

Well I don't have an EGR any more now thanks to new headers lol. But I never really thought about it taking off carbon of the charger that's deff possible. Thanks for the tip.

I got my o2 sensor fixed yesterday, but now i have an EGR code, so i assume the smoke was from that.

Semi-old thread but I wanna double check on something




It's been suggested to use that center vacuum line on top of the blower to avoid sending it through the rotors, but that looks to me like it would go right through the blower and rotors from there?
Where should it go if not there? pics? Really dont wanna kill my supercharger or ruin it's efficiency.
Where does it go if not through the blower? Straight into the LIM?

Obviously you dont have to take your supercharger off but like it was said before under the snout of the superchrger on your lower intake manifold (LIM) there is this fitting thats casted into it. go buy a hose thatll fit over this and put the other end in the bottle

Here is a picture with arrows pointing to it. Picture is off of google and i drew the arrows on it. Photo is not mine.

How exactly do you go about when you want to pour it into the gas tank? I heard when its 1/4 full, you dump it in, then fill the rest of the tank with gas, and let it run.

Stick a vacuum line on the t under the supercharger snout and shove it in the can of seafoam and run the car until the can is empty and then shut the car off. Wait 10 min or so and restart the car and enjoy the smoke show.

Ok so..



The line from the vacuum tee under the snout runs here to the bbv and in the other direction to what I think is the map sensor?



So I would just pull it off the valve here and plop this end into the can, let it suck the seafoam up like a straw? Then it'll go directly into the lim and not touch the sc rotors.

yep should work

I just did that FriboRage.
...so far so good.

Do you guys think this would distribute to all cylinders? Kinda seems like 1 and 2 would suck it all up.

E in, take your heads off and lets see the piston tops!

Has anyone tried a homemade seafoam? I have heard that the majority of the seafoam product is a common and inexpensive chemical and that you can make a gallon of your own for what the pint costs. Anyone tried this or know the recipe?

Seafoam is good stuff and I usually do the full treatment to all of my cars at least annually, but it gets expensive. A homebrew would certainly be the way to go if I knew the recipe.

Nobody has tried or heard of a homemade recipe for seafoam?

Wow !!! I knew I would get a response to this question but not so many. But the more the better. Cool !! So check it out... I overheated my 04 and don't have too much money to rebuild the complete motor so I did a valve job and now my car is smoking . I'm starting to think the new compression on top is to much for the rings and was wondering if this stuff would clean them so I don't have to tear it all down again . Thanks for all answers.

It certainly wouldn't hurt to try, but cleaning the rings is not going to increase compression. Best case perhaps you have a ring that is stuck and perhaps a good cleaning will free it, but I don't personally think seafoam is going to fix your problem. While you had the heads off would have been a good time to do rings if that was a problem. Either way, seafoam is good stuff and it won't hurt to give it a try.

You need to take the oil pan off too, which becomes "a job".

Then you need to check all tolerances, and machine or chuck if they're out.

this is crazy talk lol

did you have the heads off to work on the heads? or just replaced the springs? could be the valve seals took a dump and its smoking due to that, especially if its only smoking after its been sitting at first start up.

your compression has not changed. unless the cylinders are shot to hell, unlikely.

Yes I had the heads , and we didn't think about the rings , but were gonna do a compression test to see what's bad
