Little Sea-Foam Trick

[dizzy6984]

I work at a repair shop, and ive driven alot of before and after's... We use Sea-Foam in a machine to cycle it throughe the motor, but heres a little trick to all of you who are using your PCV hose to do the app. after all is said and done, take a tooth brush and some sea foam and use it to clean out the bore of the throttle body, and butterfly, expecially where the butterfly seats, then wipe it down a bit and drive...

Ive done this to several cars and i can say i have felt big improvements in the way they run idle, and accelerate, this is worth the while.

With my truck, i took the throttle body off, only 4 8mm bolts, and cleaned it out that way and used a baster thing to squirt sea foam directly into the intake ports...

Try it out and let me know about your results...

heh a toothbrush wouldn't cut it on my truck, you would need a sandblaster to get all the varnish off the inside of my TB and upper intake manifold.

One of these days I'm actually going to figure out how to do the PCV method on my 5.0.

Wrong Wrong Wrong, this stuff cuts through carbon build up, like paint thinner to paint. Trust me, the other day i did intake gaskets on a 97 Lumina with 320,000 miles on it, and it had some major build up, but the Sea-Foam took it right off... Another thing i always do when im doing intake gaskets is pour some Sea-Foam directly onto the valves through the intake ports, and let it sit till i get it all back together... It really helps.. You'll be amazed by what that stuff and a toothbrush will do...

So i tried this, and a tooth brush didnt do SQUAT! but steel wool! oh momma, this works great, just not with a toothbrush =P

Maybe he uses a metal tooth brush, you would think it would be rough on the gums!! Great idea, I will try this next time I have the intake off

its tarter control man...thats why he uses metal toothbrushes...duh. but i used the method yesterday......i idle a lot smoother...im a happy camper. thanks man.

Well let me clarify, I used steel wool on the upper and lower intakes... which a toothbrush was not fit for.

I used a toothbrush for the smooth surfaces of the throttle body, which worked like a charm.

You will need roll of paper towels while you are doing this =) Gets kinda messy.

If you plan on cleaning out your upper/lower intake with this method, make sure you go back and rinse/clean the parts out with warm, soapy water when you are finished sea foaming. You don’t want to suck fine metal particles into your combustion chambers.

Can sea foam clean the iac? I cleaned mine with electrical cleaner and q tips. i was afrasd to uise sea foam on it.

I just used Amsoil Power Foam on my IAC. I'll find out in a day or two when I put the intake back together if that was a good idea or not.

I am replacing the EGR sensor on my '97, so I pulled the TB, and elbow off as well (I think they call this the EGR extension, or something). I have a heck of a time cleaning that thing out. Found out the gasket remover removes the paint! Also found out that part of the inside of the elbow appears to be painted, which seemed odd. Not sure if it mattered at all, but the "EGR ports" on the housing had a lot of buildup. I tried to clean it as much as I could.

Not sure what else I should spend the time to clean up while I'm in there. Any thoughts?
