Project 3.4 Camaro

Didn't feel like reading all these posts, but just an FYI if it hasn't been said already, I don't think its the seafoam itself, but rather the stuff it breaks lose, that can mess up an o2 sensor, I have done used seafoam on 3 cars now. 2 of them needed o2 sensors replaced immediately after, from now on I will be removing the o2 sensors and plugging the hole to do this.

ive heard of tranny fluid before. ive been useing water down the carb for 20 years. it does the same thing. your basically steam cleaning the combustion chamber. go out & beat the krap out of the car, youll hear the carbon deposits fly out of the exhaust.

Seafoam is one snake oil that really works, so many like it but none work the same.

In the motorcycle world it fixes so many funky running problems run strong at half a can to a tank [2-3gal on a bike]

BUT

Beware of the tranny stuff they sell, trying to losen up a TH350 [shifted in all gears fine manualy at all times, but not automatical once warm] so try some of that to losen it up, maybe a sticky.............

Anyways after adding it, the front seal on the trans leaked fluid like a terrorist who took a .50 round to the chest.


But it only leaked like that for 1 day then stopped and never leaked again?

Had a new trans built.........

Saw this thread bumped up the other day and read every single post. Decision was made to go out and buy a bottle to try. I just recently bought a 1992 Camaro RS with a 350 swap, runs really good but I always thought there was a little left in it. Ran a bottle of sea foam through it today and she really woke up! Runs like I assume she did when the 350 was dropped in her. Mine did not smoke much at all, a little on start up and a little down the first side street, that was it. I assume thats a good thing!

Just finally did mine today. Really woke her up. Here's the videos as promised.

I used some of this a long time ago in my 77 dually. I put a can in the gas tanks. 1/2 can in the oil and 1/2 can in the intake via a vacuum port. Slowly sucking it up, then when there was a little left in the bottle let 'er have it till it choked itself out. Let it sit for a few minutes and crank it up. The 400 smoked like a 70's concert with way better throttle response and a smoother idle. You do want to make sure you change your oil within 300-500 miles. You don't want that stuff floating around your engine too long to mess up your bearings. When you change your oil it'll be black as the devils dick from all the crud.

Would this stuff stop my engine from running so rich?

84Vortec

In most cars iv used it in it smoked maybe a max of 30min, although when i used it in my 81 prelude it smoked from SC to TN and that was a 4 hour drive. but the car didi have over 400k miles on the ticker

HawkZ28

That is totally dependent on on the cause of it running rich.

SKELITOR117

iTrader: (3)

That is true. COULD it help I suppose is a better question. And I gather from your statement that that is a yes.

Mike92Firebird

iTrader: (3)

I'm not sure it how it would help with running rich. Usually that's an issue with the tuning or a bad sensor, which seafoam has nothing to do with. It essentially cleans the crud outta your engine.

southbay08

If there is a small piece of debris that is occluding one of the openings causing the injectors to leak, the seafoam may help..... however it depends on whether or not the injectors are the problem.

SKELITOR117

iTrader: (3)

So it would clean the spark plugs right? I know those haven't been changed in a while. It's also ideling at around 2 grand. Is that normal?

southbay08

The end results or effect that seafoam has is all dependent on the condition of your system.
Project3.4Camaro is correct, whatever breaks loose has the potential to flow through the lines ultimately causing problems, however it is a good product, it is EPA registered, and many people have had good success with it.

SKELITOR117

iTrader: (3)

Yup. I plan on doing it. I'll just have to see what it fixes and what it breaks.

Mike92Firebird

iTrader: (3)

Holy crap! 2k is a very high idle. Is it throwing a check engine light? Mine idles around 800. Seafoam worked very well for me though, got rid of a tick and gave for a much more steady idle. I'd say give it a shot!

reefland

Where is the vacuum line for the brake booster on a 5.7 TPI located?

HawkZ28

iTrader: (2)

2k sounds like a vacuum leak!

Do half the can in the tank and the other through the brake booster vacuum hose.

You'll find any exhaust leaks too

HawkZ28

iTrader: (2)

Captain Obvious says on the brake booster

Drivers side fire wall. Black big round can the brake master and reservoir attach to. Should be on the black round can somewhere on the front engine side.

reefland

Roger that. Plan to run a can through my Z after reading the reviews.

Mike92Firebird

iTrader: (3)

Sounds good! Let us know the results!

SKELITOR117

iTrader: (3)

Yah. It's been sitting a while though. Still, I started it and even when it got warmed up it was still at around 1800. I'm going out for various parts and stuff tomorrow. Seafoam will be on the list. I plan on doing the oil after that because I here after you run sea foam through it gets really gunked up. Probably a good Idea to let it run till the fuel is really low and then fill it up and change the oil.

Carlos773

iTrader: (3)

I would avoid Seafoam. Try finding your problem first. Check your TPS, Map and routing to it and see if everything is hooked up right. A L03 is a very simple engine, even my 13 year old cousin can probably find whats wrong with one.

Mike92Firebird

iTrader: (3)

Yea I'd recommend to change your oil within 300 miles or less of the treatment. Chances are it'll make it nice and black. Seafoam is a treatment you're not suppossed to do very often. Every 15-20k miles is what I've heard. You can try running some fuel product through the gas too. I'd do it independently of the seafoam though. Like use the gas additive, run the tank low, fill up to about halfway, and give her seafoam. Make sure you follow the thirds rule for the seafoam. 1/3 gas tank, 1/3 in oil crankcase, suck the last third up through the brakebooster line, let it stall and sit for 15 mins, fire her up And drive the hell outta her. Do some spirited 0-60 runs in an open space if possible and enjoy the smoke show. Like mentioned above, when the car is sitting still, give it some good revs and make sure the Only place the smoke is coming out is the exhaust. Otherwise you've got exhaust leaks.

SKELITOR117

iTrader: (3)

Yup. I think it may have a vacume leak, and if that's true the sea foam fill fix it from what I hear. Also it doesn't want to start today. Think I just need to start a thread for these problems.

midias

Probably wont fix the leak but it might help you find it if white smoke comes pout of it.

SKELITOR117

Yes that is what i ment. I know it doesn't actually SEAL anything.

Seafoam it anyways for us and take a video!

haha. I better make sure all inspection stickers are updated first. Can you imagine being a cop and seeing a car with flames on the front and thick smoke billowing out the back fly past you? You be like "no way in HELL i'm not pulling that car over!"

Black88Z

Hahaha I seafoamed my 81 TA after I got it and my neighbors (on side with exhaust facing them lol) came running outside thinking there was a fire XD it lit up the whole street! Filled it with white smoke. It had sat for almost a year, and i ran the seafoam almost right after I got it running. I am a HUGE fan of seafoam, it relly works wonders. But as said already, change oil quickly

seafoam is a snake oil, it does nothing except produce a lot of smoke.

i took my heads apart, and the backsides of my intake valves were completely covered with some thick carbon buildup (worn valve guides and seals). i let a few of the valves soak in a container of sea foam for 24 hours. it was just as hard to remove the carbon buildup from the valves that i didn't soak.

i even tried applying my torch to the soaked valves to see if heat would have an impact... nope. it was still just as hard to remove.

don't waste your money on this garbage. i'm going to run my remaining stocks of it through my friend's junker field cars for dramatic effect.

iTrader: (3)

let's for a moment assume you are correct... then explain me this...

If I used one can of seafoam (which I did when I first got my car) the car stumbled, and there was a LOT of smoke. So much smoked that I wondered if it would ever stop. The car ran better, so the next month I did it again to see what a second can would do. The second time, there was a lot less smoke, but not much difference. The first can obviously cleaned something, or it would have smoked just as much the second time

kmcn47

also, you used it wrong, from what i've seen and read and heard, soaking things in seafoam wont do anything, you have to run it through the engine, what seafoam does is burn at a higher temp then ordinary gasoline and its through this higher temp that it burns out all the carbon buildup on all the moving parts..........that or i am completely ****ing wrong

Seafoam will help clean it out and run more efficiently.

BUT, if your engine & jets are clogged, really dirty, and chugging a luggin a long.... don't mess around .... use BG Products. It's about $24 a can and mostly sold at shops, but .... it's worth every single penny. It can take a car from barely running at all , to running like a champ after running it in there for 10-15 minutes.... and will do more as you continue to run it. If you really want to clean it out, that's what I would recommend.

89RsPower!

Try using a smaller vac line, using one as HUGE as the line off the brake booster would very easily suck in enough to quickly hydro-lock an engine and possibly do serious internal damage such as bent rod(s)

Mitchell King

Have yet to try it in my 91GTA but I will vouch for SeaFoam. I used it all the time in my motorcycle in attempts to get power back. Mind you this bike is a 1989 Kawasaki Ninja 750R and it sat for a good 10 years in someones back yard. *BE WARNED* if your working on an old engine this product will open old wounds if they are there. I ended up having to replace my head after putting it in the oil cause it broke so much crap free it ended up locked up a rocker and blowing a hole in my valve cover and bending a valve. But to it's defense on rebuilding the engine I found almost no oil or carbon buildup in the engine what-so-ever so it did it's job VERY well. Just be warned that an old engine may have issues this product will *break* loose. No matter what I will use it on my 91GTA in about an hour when I get home. Wish me luck!

ScottsBlown

Read all the rave reviews so i tried it, but i didn't notice much, if any difference..

Ran 1/3 through my 89 TAs intake (51k, stock) and 1/3 though firebirds (94k, stock), last 1/3 in FB gas tank. Slowly sucked it up through the brake booster vac line, let them sit for 25 min, then just revved in driveway till they stopped smoking. They both smoked decently, but neither smoked very heavily like I thought, perhaps that's good tho. Took them out right afterwards too, didn't notice anything on the TA, was hoping to unlock a lil more power The firebird may be a little smoother now, but not much. Of course neither were really acting up in the first place.

**Will I have to change my oil now? Hope not did em beforehand!** (stupid, stupid..)

ScottsBlown

Thought of a few things I may have done wrong; I plugged the booster vac line back in before I shut engine off, waited 25 min to fire up as apposed to the 5 min they suggest and I didn't let it stall out as others have done..

The brake booster on TPI cars hooks up to the very back of the manifold, it will get your seafoam in the back cyls but not the front. I used the larger of the 2 lines coming off the evap canister to the TB. It works flawless there and I had the white smoke, not when using the pcv or brake booster line.

Do watch the water temp though, the temp on mine shot up to about 250 on the gauge (probably a little lower) but after running it hard and shutting down it DID boil water in the overflow.

Also, after seafoaming when I wanted to shut the engine off it didn't shut off, it dieseled on and started knocking, I turned the ign back on so the injectors fired and the knocking stopped and then had to pull the battery to be able to kill the engine. Its probably that damned MSD box igniting super lean seafoam fumes (still weird since it's ign switched, can't imagine it's auto ignition from glowing carbon deposits) but it is a thing to watch, if you do it..be ready to disconnect your battery.

Where did you put the seafoam.. in your gas tank?

walkthelin3

im alittle hesitant to try this product again.. i used it on my gf's toyota paseo after doing it on my old ford tempo.. and she ended up blowing blue smoke.. used it on my camaro, blue smoke.. im afraid if i use it again this time on my firebird or any other car.. ima clean the engine too much and reveal a leak... i dont want blue smoke again =[

HiPerf_Chevyman

The blue smoke is normal when using seafoam..... I did a 120K mile 4.3 s-10 once and boy it smoked for the whole week.... Ive used alot of it, and never had one make a leak or reveal a leak or make one burn excessive amts of oil.

HiPerf_Chevyman

well uh, what do you think happened? seafoam ate your piston rings? haha well to be real.... Ive seen these valve covers sludge up and the PVC will suck in oil......

KnuckleDragger

The Seafoam isn't supposed to work by letting things soak in it. It basically pressure STEAM cleans the valves. When it is slowly introduced through the intake, it is evaporated into steam when the engine fires... steaming cleaning and blasting gunk off the valves.

Not totally true, I use sea foam to Soak gunned up and deposited emulsion tubes from the carbs in motorcycles. That's common practice.

It's cheaper to make it yourself. http://hildstrom.com/projects/seafoam/index.html

Well,I tried Seafoam on my "91" chev k-1500,5.7 tbi, w/309k on it. Before adding, oil press runs steady 60lb hot or cold, and gets 18-20mpg put 2/3 can in the gas(about 5 gal) and the rest into Tb,let sit 15 min and started it only smoked for a few min and not very bad. Im not going to add any to the oil, the motor is tight ruin a good thing
