seafoam works! [merged]

[cranky]

I have been using seafoam in heavy equipment engines for years and I have seen it make dramatic differences in performance and idle quality. I recently had a problem with low power from my 91 talon. It felt like the computer was removing timing. Normally what I do is find a secluded spot because you will smoke down your whole neighborhood. Start the engine and let it get up to opperating temp. I remove a vacum hose and put it in the can and rev the engine to about 2500 rpm and suck the can dry. Shut off the engine and let it sit for about 15 minutes. Then start it back up and run it down the road, and run it hard. This will remove a substantial amount of carbon build up from the combustion chambers.

if you have manifold or around leaks, it will shoot flames.

Sea Foam is the SH**!!! i love this stuff and will use it every oil change. I never dump it in my gas because i think it will become too diluted. I just dump about half the bottle in the crankcase, and throw a vaccum line in the bottle and let it suck the rest up. Then, as soon as the bottle is empty, turn off your car and let it set for about 5-10 min. Then start up your car and make sure that you are in a very ventilated area. Some people say that the smoke/carbon isnt that bad when it comes out, but my car was terrible. I did it in a semi shop, and there was so much crap that came out of my exhaust, i could not see out of the garage door (which is obviously huge because its a semi shop). It was like the movie "The Fog".

I have about 200 miles left on my oil before i change it, but when i sea foam it i am going to get pictures of huge cloud(s) that it should leave. I dont know if it will be as bad the second time though, but owell!

yea, its pretty noticable if you have an exhaust leak. I didnt quite get flames out of the small crack in my header, but at least i knew where it was.

Also, i picked my bottle up at autozone for $7.16 out the door! And while your at it, i would suggest new spark plugs. It is not reccomended by everybody, but some people say to do it, and mine were actually pretty much done for after the use of sea foam. Hope this helps man

Seafoam did make my plug's electrodes turn into ovals. Id also say to change your oil.

Me and a friend just did it this morning on his new junkyard bought 1g eclipse, car has 260k miles on it. It smoked so ####in bad, the cops came with the fire dept. The one cop said that he does it to his car evey 60k miles and told us how is 89 IROC runs better then ever after he does it.

 

[chicagoavenger]

So do you do it off the crankcase or the brakeboost?

I try not to use the brakeboost because I think the line is a little too big.

 

[sniver]

although i see some high milage questions, none that i saw are at 185,000 miles, i recently did a head rebuild when i got the car and it has no ridge at the top, and all in all looked pretty good, would you guys say try it (I was just gonnna put it through a vac line, I see the danger of puttign ti through the oil), or do you think its a bit to risky cuase its my daily driver?

What do you think is risky about it? It will clean carbon off of your pistons. If hundreds of people so far have had great results and no problem, then I don't see how your daily driver could be any different.

 

[Wufei]

Only 1g guys use the brakeboost right? I don't see how 2g guys can reach the brakeboost line (unless I have the wrong one ).

 

[alex99gst]

Any line that leads to the intake manifold is going to have vacuum while the car is running.

 

[Wufei]

Yeah, I've been using the line that goes to the BOV, but was wondering if there is a better one to use.

 

[alex99gst]

Because this thread lacks many pictures, I decided to take some during my seafoaming today. As you can see, there is a thick cloud of smoke towards where the exhaust exits behind the car. When I started the car back up and drove off this cloud was multiplied x 1000 Good thing I did this in my driveway I found some exhaust leaks and fixed those, but about 5 minutes after, I still had a nice continuous stream of smoke coming out of the dump tube . For those who are wondering, I put some big flexible tubing over my exhaust in an attempt to not dirty up the bumper any more than it already was. When I took it off I found a lot of small black chunks (figured it was built up carbon).

Anyway, I used one line on the throttle body and 2 ports on the intake manifold to suck down the seafoam. I did this to make sure that everything was cleaned equally instead of half of the engine getting cleaned up and not the other half. All in all it worked well, smoked a lot, and now I have a much much steadier idle.

It actually can be risky, and if you are one that gets "screwed" or always has bad luck, your motor could come out very, very bad. If you think about it, generally the older your engine is and the more miles you have on it, the more carbon build up you will have. Correct? Well when you have a ton of carbon, and it keeps adding on, pretty soon you will start to get carbon inbetween your piston rings and cylinder walls. And after a while, the carbon will dig into the walls, leaving scratches. Then the reason you keep all of you compression is because the scratch is sealed off with carbon. Once you remove that carbon with Sea Foam, there will be gaps inbetween your walls and rings which would cause a compression loss.

Just keep that in mind on higher mileage vehicles. BUT......do not think that i am trying to scare anybody, because i do know that many people have used this on high mileage vehicles, and never had a problem. So i am not saying not to use the sea foam, but there is a small chance that you could have that problem. Its actually very unlikely, but possible!

I think that you'd have to have alot of miles based on:

I just used it on my friends 380k mile '92 B2600 and it ran better than ever. Yes, 380k mile.

Ive now used it on 4 different cars, all with great results...

 

[2DaTrakNow]

I think that you'd have to have alot of miles based on:

yeah i know...thats why i said that it wasnt the case on all cars. I also said that there is a very unlikely chance of this happening. I only said that there was a possibility!

I can't believe I just read all 10 pages.

I treated the engine lastnight. I sucked quite a bit through the PCV then hit the BOV line with a little. I turned the car off for 10 mins, started it up and had a nice little smoke show wiht black lights and yadda yadda...(not really) I cranked it up and let it idle for 10 and I then took it through the neighborhood and made a few WOT passes on my "private test track" and came home and let it idle for a good 10 mins after also.


This morning after letting it sit over night, I changed the oil and added some oil treatment as well, took the plugs out since they were brand new and took a piece of sand paper to them and cleaned htem off. Tonight I noticed it was still smoking like something horrid at idle? Whats going on?

 

[elfroggo]

Just drive it a little more and see if it goes away because it should.

If not, then you might be one of the unlucky few where carbon deposits were cleaned away and now you may be burning oil. But I doubt it, just drive it off.

 

[andymoraitis]

When you treat it through the BOV line and it sucks into the intake, you need more than a few WOT passes to get rid of it. On my old 2.0, I'd have to beat the snot out of the thing for 10-15 minutes to get it to stop.

Chances are you didn't really blow it all out.

 

[my98GST]

I dunno, I made quite a few wot passes lastnight and then today i was liek well maybe i should just baby it and then I just got pissed off and beat it like you would a red headed step child and it still smokes at idle. Only at idle...

 

[my98GST]

Its def. not a good feeling though Does this mean I'm going to have to spend another 45 bucks on oil and a filter?

 

[GreddyGst]

If it makes you feel any better, I have a friend that seafoam his car and got had some unwanted leaks and his car felt slower after the seafoam. Turned out that the carb deposits was the thing keeping from leaking haha *note* I said had because he sold the car already

 

[my98GST]

Ooooh thanks a lot asshat That makes me feel 27 times better Nah it def. made a pretty big difference I think. A lot smoother idle (which was fairly smoothe before but no jumpy idle or anything) Made it feel a tad bit stronger, made it a lot more smooth under normal driving.

I was scared to death that would happen to my car since its got 156k on the stock motor.
