My SeaFoam Experience - Toyota Nation Forum : Toyota Car and Truck Forums

After reading all the great comments about SeaFoam, I decided to use it on my sister's 97 I4 Camry (88000Miles)

So, I went to the Autozone and bought 2 cans of SeaFoam. I am planning to use it with all 3 possible methods, gas tank, crankcase and brake booster line. Crankcase and gas tank are pretty stright forward, just pour the dame thing in.

Brake booster line was the interesting one. Fearing what SeaFoam may eat up the rubber vacume line, instead of disconnecting the vacume line from the brake booster side, I disconnected from the intake manifold side. Of course, I now have to find another rubber tube to connect to the vacume port, so I can use the tube to feed the intake manifold.

I had the engine running, and disconnected the brake booster line. Immidately, the RPM surge to about 1800RPM !!! That was not something I have expected, since no one had mentioned in their post. Well, I proceed to connect my own rubber tubing to the vacume port and start allow the tube to "suck" SeaFoam into the manifold. At this point, the engine RPM varies, it appears to be effected by the amount of SeaFoam being feed into the intake.

Here comes the weirdest part. After all the SeaFoam had been feed to the engine, I turn off the ignition and remove the key... THE ENGINE CONTINUES TO RUN!!!!

Whata!!! I quick pull the rubber tubing that is still connected the vacume port, a stream of smoke rushs out the port and the engine finally stop... Well, rest of the story is pretty much same as everyone elses, massive smoke, etc...

Have any one experience any thing like my "DIE HARD ENGINE" while using SeaFoam???

I've been reading SeaFoam stuff for the past 45 minutes (I'm a quick reader). It seems you are the first to experience this. Others have reported a drop in RPMs while others say it goes up to 2800 RPMs. One guy did mention he had someone in his car to keep it at 2K while the car "inhaled" SeaFoam. What tubing did you pull when the engine failed to turn off? Why did you pull it?

yeah when i first poured in seafoam, it'll rev up then it'll feel like dying so i had to keep it at 2K.......or it would just die on me. turn off, the usual white smoke.

neither of my cars really smoked a whole lot when I used seafoam. One had 90k on it, other over 170k. I guess I just keep em real clean

Yes the engine will continue to run after the key is pulled if the brake booster line is not connected, just cap the line and it will die off. Not the first person to experience this.

How much of the can did you use? You are only supposed to use about a 1/3rd of the can.

It simply leaned out - you just doubled the amount of air it can take in at idle.

That is common. If the combustion chamber is up to temp, you can burn any type of oil - even in the "low compression" toyota gas engines simply off compression and heat.

The engine simply diesels on the naptha oil in seafoam.

The same thing happens if you blow a head gasket, and a lot of oil is dumping into the combustion chambers. The engine will run off the oil igniting until the fuel supply (now oil) is exhausted.

Get the engine really warme dup and squirt a 16oz spray bottle of water into the intake manifold. Do that a few times and you'll clear some of the carbon out of the combustion chamber.

I added seafoam to my crankcase today and let it run, it didnt smoke at all

. maybe it only smokes when added to the booster line.

Toysrme · 07-02-2005, 07:40 PM

Smokes like crazy into the intake tract - smokes a little bit in the fuel system if you pour in the whole can like I do. It only smokes when it's being burned.

Lord_Anarchy · 07-02-2005, 11:42 PM

I went ahead and put 6 oz. in the Camry and some in my pop's '89 'Rolla. My car didn't smoke when I had the Cam snorting it. My pop's did smoke a bit. Anyways, I didn't restart it after 5 or 15 minutes, I'm gonna wait until monday morning to fire the bad boy up. Does it clean or do anything for the EGR? We both are gonna add it to the crankcase and fuel systems. I also plan to put some in the Mercury lawnmower after I scrape the crud under the deck of the damn thing and lube it up.

2 bottles @ 4.79 each.

Not really. I find Seafoam does best in the heads, back of the valves. Helps some in the combustion chamber.

Water cleans the combustion chamber out better, while the only think that will clean the itnake (upper intake on a v6) is hand power. You're not going to spray the stuff away.

Lord_Anarchy · 07-02-2005, 11:50 PM

How do I use the water? Disconnect the intake pipe and spray into the throttle body?

JAMIEMILLER · 07-02-2005, 11:57 PM

does anyone have a picture of the brake booster line you were using...or a idea where it would be...

i know its probably a noobie question but i would like to know. i have a high mileage 224,000 camry and any tricks to make it work better would be great..

Lord_Anarchy · 07-03-2005, 12:12 AM

JamieMiller, check out this thread. http://www.toyotanation.com/forum/t74757.html

Brungold shows a pic of EXACTLY what line you would let SeaFoam enter your intake tract. It would be post #4 on the thread.
