Seafoam induction?

[Robert.K]

Was reading another post, and wanted to know has anybody did this seafoam induction thing with a vacuum line for a 2000+? I use it in the gas tank cause thats all I know, and I like how my shit sounds like its cammed afterwards! Someone chime in if it can be done, what are the benefits of doing it that way, and how to do it.

i swear by seafoam...ive used numerous times on my old 99 sierra 5.3 and i use it on my 04 tahoe 5.3 it works wonders

is this you speak of????

 

[navy34]

Yeah, I've ran it through my vacuum hose and it worked out pretty well. I usually do about half in the vacuum and half in the gas tank, it's up to you though.

where do i get this foam from and what are the benefits of doing this ? Can someone chime on this ..... thanks

 

[Robert.K]

What vacuum line did you use? the one from the Brake booster?

Autozone or any other auto-parts place sells the stuff
It helps to break down and get rid of all of the carbon build up in ur engine, which intern restores power lost from the initial build up.
and btw it's just called seafoam it's actually a liquid.

I've done it to on my '02 denali, worked pretty good, just pour half of a can into something so you can see you are only sucking up half a can and suck it up kinda fast through the vaccum tube at the brake booster , just fast enough to not kill the motor but suck it all up in a speedy manner, as soon as it is all sucked up have someone turn the truck off ASAP, let it sit for 10 or more minutes and then start it back up, rev it up a few good times and go for a spirited drive!!

i poured it in with the vehicle off then started it with it in the hose and when i hear it start bogging i turn it off...works about the same way

here's a pic on my 05 where the vacuum line is located where I just did mine. benefit you ask? according to seafoam, it cleans the pistons I believe. you can check out their video on their website under motor treatment. I did it exactly how they say to...1/3 can through the vacuum line(this part takes longer, just gotta do a little at a time to keep it from stalling until you want it stall), 1/3 where you put the oil, and the other 1/3 in the gas tank

took me a minute to realize that was the hose, cuz it looked rigid, like metal, but it flexes

now....I didn't get any smoke after this process, when everyone else gets a shitload....maybe I should have used a different line? Anybody?

It dissolves built up carbon deposits and allows them to pass out through the exhaust. I run seafoam through my rig every year or so. Good stuff.

It's a little hard to tell from the pic which line that is...if its the one that your PCV valve is attached to, then it's the right one (I have an 00, it's set up a little different). If there was enough vacuum to pull the seafoam into the engine, then you probably did it right. How many miles are on your truck?

 

[brndns_hoe]

only about 60k, yeah it had good suction, like I had to do a little at a time, to keep it from stalling.

 

[Rivieraracing]

I had my wife hop in the car and keep the idle up with the accelerator pedal, worked pretty good and fast and kept it from stalling, plus she was able to turn the car off right away when it was done!

is there a mileage recommendation for this ? Will this be okay on my 06 Tahoe 5.3 with 48K miles on it ? or should i wait ?

You can do it whenever, I forget what the technical term for what is in the stuff but it is not harmful to your truck

 

[tybardy]

good stuff... hey brndn... you need to use a different line, the line you are looking is on the brake booster. if your truck has hydroshock breaks or whatever they are called then the line you are looking for is on the passenger side connecting the intake manifold to the block. You want to disconnect the hose from the block side if i remember correctly

 

[brndns_hoe]

damn, well it was the PCV line I used...but I'll look for that one on the passenger side, thanks!...

 

[withac]

From what I've been told you don't want to suck it up too fast. If you get too much straight liquid in the cylinders you can hydro lock (I think that's what they called it) the engine and do some serious damage, like bent rods and shit. I've done it on my 2,000, just let it sip it like they said, as fast as you can without killing the engine. I've heard of people sticking the hose right in the can but have been told that's when you can do the damage.

 

[tybardy]

just play it safe, its really hard to **** things up with this stuff... just read the directions on the bottle and follow them... if you do that you will be 100% fine.

well i got some smoke this time, found that line Ty....wasn't a shitload of smoke, but i'm happy, lol...although I was talking to Hyde and he has a good point, what's to bet most of that smoke is just the seafoam burning off? I don't think it's necessarily all the carbon. Not saying it doesn't do what it says it's supposed to do, but I think the smoke would be more from the seafoam(petroleum based) burning off. either way, I got to blow some smoke
