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.

More like I'm stuck in the noob forum for a bit.

The 420a Bolt on Tech section is open for New Members to post in.

And yes I guess I didn't realize he had the 4g63.

The majority of this sites members have factory turbo cars.

I have a 1992 Talon TSi with 72,000 miles on it and I heard about runnin seafoam through it. Is it worth it?? Anyone tried.

Here's a massive thread on it: http://www.dsmtuners.com/forums/showthread.php?t=222686&highlight=SEAFOAM

 

[staticbrainwash]

I did it on my new motor after fixing idle surge and boost leaks. And even after 5k miles it helped A LOT. I'd recommend it.

There are a few ways to run it through, but after you do i would recomend changing your oil and plugs and ect. After I have ran it through my esi (90k), a 240sx (130k), and a 300zx (140k) and they all made an awesome smoke screen and the car felts smoother at idle and just felt more fresh in response.

But then again, when I change plugs and other small things in my head I think the car is running faster

hey guys quick question....i was reading the thread about using sea foam but all i can find is how to use it on 91+ cars...i have a 90 which line do you use it threw on a 90...if i can get a diagram that would be great thanks!

 

[silver bullit]

You put it in any lines off the intake mani this has been coverd many times 90-94 are the same minus some ecu/connector clips.

 

[bOOst tsi]

thanks for the quick reply...ima try this tommrow see how it goes

I'm tempted to try this out..
if i dumped a whole can in my gas tank only, would I still need to change the oil and/or the spark plugs immediately afterwards?
also would i still notice a positive improvement if i put it only in the tank?

My NA 97 4G64 seemed to be held together by the crust,after I seafoamed it (evenly split through the oil,tank,and intake) it has started to go downhill and leak oil around the plugs.I changed the plugs,oil,and filter afterward.

If you know your engine is about shot like I did,it may be a good idea to skip this.

I noticed you can get seafoam at WALMART now. It was like $5.50. Liquid type I believe.

 

[turboglenn]

I was going to post on this teh other night and today found this thread. I am a firm believer in seafoam and Mopar combustion chamber cleaner. I try and run it through my engine about every 25k miles or at least once a year. LIfter tick and idle problems are always cured quickly ( as long as theirs no other underlying problems)

I had a friend over to holf my TB open to keep the revs up and used the vacum line nearest teh PCV line and when my buddy sat there and heard my lifter tick dissapear and my idle being so smooth afterwards, he went and got a can and had me put it through his car ( an older taurus ). Needless to say he was pleased.

Not to sound dumb but this has never been mentioned I don't think. Do your run the liquid or the aerosol through the vac hose?

I am positive it has been answered before in these 400+ posts. You can run either through the vacuum line.

 

[crimsondragon]

Does seafoam clean the TB and TB plate? I only ask cause cleaning the TB was next on the list of things to do to my car. If it does, this sounds like a good way to do it without removing the TB.

 

[rich3389]

You dont have to remove the TB to clean the TB plate anyway. zBut you can get seafoam deep creep.

I wouldn't think so (otherwise you'd have to do this anytime you added a fuel injector/system cleaner). But I'd recommend doing more than just adding it to gas tank. But if that's all you do, at least check plugs and oil (on dipstick) to make sure they're all right. OR, do it right before and oil change not worry about it!

I'd recommend taking off the tb to clean the plate as trying to clean it on the car (or even with seafoam) won't do as good of a job. I took mine off to replace the shaft seals and after taking the plate out, it took a good bit of elbow grease to get that plate to shine.

I cleaned my throttle plate on the car and followed the vfaq....A month or so later i had to take the TB off to do shaft seals, and it was spotless.

Well, from my experience, I'd say you're pretty lucky. Mine definitely didn't just "flow" off the plate. I had some nice permanent dark/black marks that took a good bit of work to remove (especially around the shaft). And I still have very faint lines where the mark ended. If you can do as the VFAQ describes, go for it!

 

[ktmrider]

Didn't read all the posts but will +1 for an excellent product!
I have used it in all my vehicles for the last 4 years now with great results. Last was on the wife's SUV at 88k miles, smoothed the idle considerably, MPG went up 1, better power, etc.
I have heard of folks fouling plugs if/when the engine was really gunked up but not the norm. I personally never had that problem even with my high mile WRX and iridium plugs.

Hi
I have been reading all the posts on here about using Seafoam. I was a little hesitant about using it because of the variety of opinions on it I've been reading, so I decided to call the company's support line. Here is some interesting info the (very knowledgeable and helpful) guy told me. He talked to me for about fifteen minutes about seafoam!

First, he said do not put a vacuum hose from the throttlebody into the can and let the vacuum suck up the seafoam--he said that could suck up too much too quickly (although granted, the vacuum lines off the TB are pretty small). He said you need to pour it into the vacuum hose so some air goes in as well.

More interestingly, he said there's really no need to do the induction method (through the intake using a vacuum hose) unless you're just in a big hurry. He said that putting one ounce of seafoam per gallon of gas in the tank does the SAME thing, only it takes longer--he said after you have run about two tanks of gas through (after putting in the seafoam), you'll have accomplished the same thing. He recommends using the gas tank method over the induction method.

He also said if you are using it as a pre-oil-change cleaner by putting it in the oil, make sure you drive for at least 1 hour before changing out the oil.

Finally he said there is no need to change your sparkplugs after using seafoam--he was surprised to hear that this is being recommended. He guaranteed me that no damage would be done to sparkplugs from using seafoam.

Just repeating what I heard, take it for what it's worth--not saying this is gospel or anything . And it's possible I am misquoting him, so feel free to correct me if this is totally wrong.

 

[silvreclips]

adding seaform to your gas will not clean the carbon out of the intake manifold. Thats why you put it in a vacumm line. So it runs down the intake and washes it into the cylinders.

Changing the plugs after are no big deal. They are cheap and probably need to be changed anyways.

 

[kenamond]

Thanks for the info! It's probably not a bad idea to know what the vendor says about this treatment. I was wondering about the pre-oil change stuff. And I usually only care about cleaning the CC with seafoam, so the gas tank treatment sounds like a good idea for that application (and the vaccuum line trick scares the shit out of me).

 

[joebor1776]

btw, about cleaning the intake manifold--I forgot to mention this. The guy from Seafoam said that Seafoam will not clean the intake manifold. So there's really no reason to do the induction method unless you are in a hurry.
