I use it every few oil changes works good at cleaning the gunk out and its safe to use .

 

I've heard people say to run it through the intake manifold vacuum lines and I've heard others use the same steps as that article says. I personally have only seen someone add it to their oil. Yes, let the car run until it stalls. What happens is the seafoam expands inside the engine and it eats the carbon away, then it rapidly contracts again and is burned up. It expands so far that the car stalls and dies. About 5 min. later you start the car, it will be a pita, and then let it run for about 10-15 min. or until the smoke clears, and yes it will be alot of smoke. It will be burning up the remaining seafoam and years worth of carbon buildup. Some people choose to use ATF fluid too. Both work in roughly the same way.

 

What is the benefit of cleaning these deposits? What is a good interval for this? Every third oil change?

carbon isn't the smoothest surface so it restricts air/fuel flow some.

 

I don't know how often it should be done, but the benefit is cleaning carbon deposits that stop airflow, is simply a better flowing and better running engine. Just make sure you clean your spark plugs when you're done.

 

after you clean your im and vacuum lines i would get a catch can of some sort to stop the buildup of carbon and oil deposits in the intake manifold. about 80$ its well worth it to keep your intake manifold clean..cause after you compleley clean it out like i did i defintely didnt want to see it become absolutly litterd with carbon and oil deposits..i had about 1/16" in there with my old engine..it was nasty

 

I use the spray can and just shoot it into the vaccume line on the intake manifold . I cant get it to stall my car either . I just have soeone shut it off while im spraying and let it sit for a while then start it up . It does smoke ALOT .

 

Mine stalled almost right away today when i was trying it we started back up and my friend revved the throttle till about half the can was used and then let it stall out and poured the rest in the crankcase

 

I did it through my brake booster line 3 times.

First time it didn't smoke much, but 2nd and 3rd time I filled a city block's worth of smoke. Fun stuff.

 

what i did was slowly sucked it in till it would bog, and id give it gas.... i didnt know you were supposed to let it sit in there, i just let it idle for 10 min then drove it.... it smokes like no other.

 

the smoke cloud is the greatest part thats how you know its working hehe

 

Man...all that smoke can't be good for the environment. Is it possible to free up too much carbon deposits and actually damage anything? A recent post on honda-tech talked about this product, and someone thought that if its the first time you use the product in your motor that a lot of carbon will free up which isn't good. Do you have to change spark plugs after, or just clean them? If you pour seafoam in the crankcase, is it a good idea to change the oil when your done? I want to try this, but im not sure if the benefits will outweigh the risks.

 

i would suggest using seafoam before a tune-up..this way once u run the seafoam thru the car u,change your spark plugs,oil,etc and feel the tru benefit of it and dont have to worry about the plugs fouling or having contaminated oil in the car...seems very logical to me to use it this way..and i wouldnt use it so frequently,once a year maybe,or six month intervals...

 

i recently changed my plugs, but i want to try this seafoam product to help remove the carbon build up on my 90k mile engine, i dont want go through the hassle and money of changing plugs again, is there any type of cleaner i can use on them after the seafoam? also, ive heard of people dumping this stuff in their gas tank, anyone tried this method? if so, did it work just as good as filtering some through the IM?

 

recomendation....

 

if you have an old battery you can drain the acid into a container that will hold it and not be eaten up...set the plugs in the acid and it'll start eating away on any buildup...thos won't do anything for your O2 sensor though.
Later,

(Oh and make sure you clean the plugs good before you put them back into the engine after the acid...(WD maybe?))

 

I just swapped out my plugs for NGK coppers, were like 2-3 bucks apiece at Kragen. I also changed my oil, jumped from 114,000 miles of dyno juice oil changes to synthetic, we'll see if I leak oil or not.

But the seafoam treatment was awesome, and I plan on doing it before every time I change my plugs (probably every fifth oil change or so).

 

Can somebody please show me a pic of where the vacuum line is located so I can use seafoam. I'm going to be using it this week because it's time for an oil change but I really don't know much about which line is which and I know I should get a helms manual which I will. Soon as I get some cash. Thanks in advance.

 

Its the big vacuum line that goes from your intake manifold to your brake booster. It is mounted on the firewall. Just take the hose off on the left side of the check valve. use 1/3 or so in the IM, then the 1/3 in the oil and 1/3 in the gas. just don't forget to change your oil.

 

Sorry but i am really new to this....how does this seafoam look like??

And where/what is the brake booster? is this the brake cylinder??

SLpornSERIES when u said "use 1/3 or so in the IM" do u mean the into the hose, which flows into the IM??

So rite after i use this i have to change my oil??

thanks alot guys and sorry for the confusing questions.

 

A.J thanks a lot for your help. I will do that on wednesday.

 

No probs. if you have any more questions about it email me. hondaxsi@yahoo.com

Yes the brake booster is on the right side of the firewall opposite of ur battery. just email me i can help you out better. hondaxsi@yahoo.com

 

do i change my oil rite after i do this??

 

is this the vacuum line? where do unplug...from the circle or the firewall??

 

anyone?
