Is doing that seafoam "cleaning" actually bad for our cars?? I did it and car runs better since....heard negative things about it though....

[pits200]

Not sure if anyone thinks its bad but that it doesn't do anything. I did it once and the car felt a little smoother but that might have been the placebo effect.

It won't hurt your engine. For carbon build up, seafoam actually soaks into and breaks up the carbon. It won't ever leave your intake as clean as a walnut blast, but it will loosen the deposits that can cause your car to not run smooth. So it works, just not as well as some people want it too. So don't set your level of expectation too high as most people have and feel that it doesn't do anything at all because they actually want a walnut finish. Personally, I’m all for spending $10 every 5 to 10k for seafoam to prevent large carbon deposits rather than spending $800 every 20 to 30k like some people on this forum. Yeah, a nice shinny new intake is nice, but how long does it take for it to look as bad as it did prior and what steps are people taking to help prevent it in the first place… Buy your seafoam and enjoy the extra money you have saved for other mods like an OCC from BMS.

i heard that it ate away on your seals in the motor is that true?? just to make sure is there any long term effects on the motor? i was thinking about doing this to my car cause its been running rough. ??

How do you get it to make contact with the carbon on your valves?

Watch the video... http://www.seafoamsales.com/how-to-u...treatment.html

Follow the directions... Again, it's a low cost option and it does remove large deposits of carbon, but it will never give you the walnut clean most people want. Regardless, it will help keep your engine cleaner than not using it at all and it's easy to use. Just make sure you follow the directions, don't take short cuts. DO NOT PUT THIS PRODUCT INTO THE DV PORTS ON THE CHARGE PIPE AS IT WILL KILL YOUR MASS AIR FLOW SENSOR LOCATED ON THE BACK SIDE OF THE CHARGE PIPE ELBO GOING INTO THE THROTTLE BODY. Always remove the air box and disconnect the charge pipe and spray directly into the throttle body. As the mist is pulled into the engine, it will coat the carbon buildup and it will start to break down the gum that holds carbon together. Eventually the carbon will break free and be pulled through the engine. Also, don't do this in front of your house because your neighbors won't like you much when you are finished. It will cause a LOT of smoke and if it's blowing toward your neighbors house and they have the windows open, they will more than likely shoot you for being a dumb ass and plea self preservation.

Who ever told you that was smoking crack.

I thought you could also add directly to the oil 30-50 miles before you change it. If done before every oil change from the beginning of ownership this should help.

true, i would not drive car or boost with seafoam in the crankcase. Let it run for like 15 min, rev a few times, then change out the oil.

Does nothing for carbon on intake valves, period. Seafoam is nothing but snake oil.

Beg to differ man. Seafoam works wonders in many engines...

[brusk]

I Agree a 2 cycle outboard owner would be screwed without seafoam and others like it. Carbon build up is the death of many outboards. But just because it is a good product doesn't mean its the tool for every application.

Why do you not recommend driving for 30 or so miles as they recommend? You think it's better to just idle and rev a few times for 15 min then change the oil?

[Wescuddles]

Is this really a topic for our cars? Hahaha. I wouldn't use seafoam on my lawn mower let alone my $50k BMW... Sigh.

Seafoam absolutely does not do anything. Waste of time and money.... It works decently on fuel injected motors, but on direct injected it will not do anything except a smoke show in your drive way. Been there and tried it.

So you acknowledgeit works but know that if you put seafoam into the throttle body it will hit the intake valves just like it would on a non direct inject motor but you cent just put it directly into the fuel.

I took the vacume line off the intake manifold and sucked the seafoam inside in the intake manifold that way. It did get on the valves. I used seafoam when I was having misfire issues, took it in to the dealer and they thought it was injectors. After getting the injectors replaced, about 3 days later the misfire and sputter came back. I decided to use more seafoam and 2 days later sputter and misfire. Took it into the dealer and they checked my valves and showed me the pictures and the carbon was caked on there bad. Mind you I only had 24k miles on my car. The seafoam did absolutely nothing for the carbon. If the carbon has harden on the valves seafoam is not taking it off, no matter how many times you use it. Seafoam is a waste of time and money on our cars.

[Wescuddles]

I think you mean on all cars - And anything with a motor for that matter.

[JJFESQ]

Waste of money...

[Vwgrk1]

If it worked well, then I would guess that nobody would do walnut shell blasting given its relative cost. I used to seafoam my WRX since it was cheap and made for a cool smokeshow, but I'd never add it to oil in a turbo gas motor that revs to 7,000 rpm. The unknown is not worth the risk, to me.

VS Motorsports in the Chicago area is doing a group buy on WS blasting, FWIW.
