Author Topic: SeaFoam Cleaner Really Works (Read 14074 times)

For you guys who want to clean your intake and throttle body and also get your engine running better use SEAFOAM. Man this stuff really works. My 85 rebuilt 22-RE was running rough and had a miss, put this through it and now it runs smooth and quiet. Really worked good for me.

Purchased at napa for about 6.50.
See pictures.

Took off hose from canister and put half the can 8oz. Through the vacume hose shut it down waited ten minutes and started it up and blew out the smoke.

Smoke for about 20 minutes

More smoke

After I ran it for a while I put the other half of the can through the pcv valve on the top of the motor. Had to run throught the valve if I took the hose off it would die.I did not put it in the motor I had the valve suck it into the intake.

Smoked for about 5 miles and now it runs so quiet you dont know its started.
Stuff really worked for me. This engine was rebuilt 10,000 miles ago but the mechanic did not rebuild or clean the EFI. The engine had almost 190,000 miles on it before the rebuild and the EFI looked like it had never been cleaned.

dang i hope it doesnt smoke like that all the time, yea seafoam is what we run in the fuel injection machines

854x4 · « **Reply #7 on:** Feb 08, 2005, 09:54:58 PM »

It only smoked for about 20 min. Now it doesent smoke at all.

would something like that work in a 22R? Just curious?

lilbuddy · « **Reply #9 on:** Feb 08, 2005, 10:14:42 PM »

I was thinking the same. The bottle says carb.'s too but does anyone know if it works?

79coyotefrg · « **Reply #10 on:** Feb 09, 2005, 05:35:35 PM »

yes it will clean your engines very well, inside and outpour somein the carb and suck some thru your canister vacuum tube, then dump the rest thru the pcv valve hole and vent hole in valve cover, change your oil in a couple days

Just wanna bump this rather than start my own thread. I tried this in the 91 cause it has a little bit of a rought idle. I was also hoping to get rid of the light detonation on inclines or under slight loads.

I poored it in through the brake booster hose, which is a pita cause it wants to die as soon as you disconnect it, but you just hafta be quick about it. The upside is it runs pretty well off this stuff, but when you stop pooring it in the engine doesn't wanna die. I ran back to shut it off so it wouldn't all burn off, but it didn't even wanna die when I shut it off! I'd recommend a wheel man to shut it off for you, but I've heard that you just poor it in really fast toward the end so it'll die on it's own.

I waited about 10 minutes (it says wait 5, a lotta people say wait atleast 20) and got very little smoke. I will try another can through this engine again later on, just to see if I can do more to rid the detonation. I also got another can and poored the entire thing into the gas tank, which is supposed to clean the injectors also as it runs through.

I poored half a can into the 4by tank, but it runs so poorly right now that I wouldn't know if it helped, plus I just did the head so it's pretty clean.

So how bout it, who else has used it, and did it work for you?

i love using it in the garage, makes a nice show for the neighbors.....

seafoam does work, works quite well too...... you can also use b12 chemtool and spray that not only in the carb, but also shoot it into the brake booster line

cheap sunglasses · « **Reply #13 on:** Dec 29, 2006, 03:41:15 PM »

I have a can sitting in my garage, I think I'll go use it right now

I've heard you should stall the engine as the last is going in and leave it in there for as long as you can (as in overnight) for max effect. Also, in a thread on another forum a SeaFoam rep was emphasizing the instructions to slowly pour the fluid in rather than sucking it in with vacuum (see last post in thread).

FYI, if you find deep creep it's basically the same thing, just in spray form. This'll work if you're going to use the small vaccuum line off the charcoal canister.

Definately makes a hell of a lot of smoke when done properly. I was instructed to trickle half a can or so in either ahead of the throttle, or via a vacuum hose at the throttle body, at a high idle and rapidly enough that it makes the engine struggle. The next step was to open the throttle a bit more and pour it in quickly enough to actually stall the engine out and then let it sit for 20-30 minutes or so.

I'm really surprised. My old AE86 made a hell of a cloud at the 76, then fogged its way up I-5 at least to Lake Blvd, and that was an engine that shouldn't have had much carbon in the chambers at all. It probably had a lot of crap built up in the manifold and TVIS butterflies, though.

kneedownnate · « **Reply #16 on:** Jan 03, 2007, 10:21:23 PM »

Well, you may remember how nasty the throttle body was before I cleaned it, so I'm guessing the rest of the intake was just as bad. I'll try another can again with better technique, hopefully with some results. Wish I woulda done this on my old ae86!

te51levin · « **Reply #17 on:** Jan 03, 2007, 10:52:43 PM »

I don't remember, but I'm sure it was horrid. They usually are.

Here's a good howto on Seafoam that I've had bookmarked for awhile, just waiting to be used:

Thats a pretty good write up. I just did my 83 for the 2nd time 1st was 6-7 months ago. It works pretty good,idle is smoother,seems to run smoother except one thing now it pings every time I start off or grab a gear I checked the timing it is where it is supposed to be, I have over 210k on it so yea its gonna ping and what not just wondering if Seafoam has anything to do with it. Any thoughts?

kneedownnate · « **Reply #20 on:** Jan 15, 2007, 09:57:35 PM »

I've been getting worse mileage since putting a can of it in the tank

Wonder if it picked up some junk and is clogging the fuel filter? I need to order a new one anyway, just keep procrastinating on it...

Will the Deep Creep hurt stuff like the TPS?

I don't know how it could. The TPS is basically sealed away from the innards of the throttle body. If you don't intentionally soak the TPS from the outside, I don't think there's any way you could hurt it by using Deep Creep, or anything else, inside the throttle body.

toybuilt · « **Reply #23 on:** Jan 21, 2007, 07:09:50 PM »

I love Sea Foam, theres others out there but I don't think they work as well. I've used it on my 67 Mercury Cougar and on my 75 Dodge D200 that has a 440 big block. This stuff works great!!

Wainiha · « **Reply #24 on:** Apr 05, 2014, 11:26:52 AM »

Bringing this back up. I usedd Seafoam in the gas never in a vacuum tube. I've read my 2000 should use the brake booster line.

Has anyone hydrolocked there motor dumping this in too quickly?

Dingman. · « **Reply #25 on:** Apr 05, 2014, 11:43:38 AM »

Every time i have ever done it i have poured it slowly into the brake booster line never let it stall the motor. After i pour in enough i shut the engine off and let it sit 5-10 mins amd then start it up and let it smoke.

Wainiha · « **Reply #26 on:** Apr 05, 2014, 12:13:15 PM »

Yeah, I think I'll do slow. I don't like the idea of stalling the engine by dumping it in quick as some have said.

OOPS · « **Reply #27 on:** Apr 05, 2014, 04:17:23 PM »

If you pour it in to fast it can hydro the engine and bent stuff, like the rods. I use it every time I have to get my rig smogged.

Wainiha · « **Reply #28 on:** Apr 05, 2014, 04:52:57 PM »

Thanks.

kneedownnate · « **Reply #29 on:** Apr 05, 2014, 07:45:44 PM »

You can also buy a can of deep creep, basically the sprayable version that is a near miracle spray lube/corrosion cutter, and spray it in the intake. I've done both ways with good results. Brake booster is a pita by yourself, gotta be quick on the draw.
