    Ok, we all know now that our direct injection engine may have problems with carbon build up in the combustion chamber...and I emphasize may...ok, chillax...now...some have promoted the use of Seafoam, introduced into the gas tank, as a way to combat carbon build up in the combustion chamber etc...I have also heard that Seafoam or other products introduced into the gas tank may cause vapor lock...look it up...Anyone acknowledge this bit of info?

    How is Seafoam in the fuel tank going to do anything if fuel itself doesn't pass over the valves, leading to the exact problem you should be trying to fix?

    Vapor lock is the issue at hand here....stay on topic

    Yeah, I'm on topic. You want to fix a problem you don't believe exists by using a product.

    Read the instructions and use Google-you're more likely to get the answers you seek that way. You might even learn something.

    no offense to OP but this...
    how is seafoam on the fuel tank is gonna help with carbon build up on the valves if there is not a single drop of fuel spraying over the valves...

    Asks dumb question, calls everyone else idiots.

    If you're trying to clean carbon buildup in the combustion chamber, that is exactly where the carbon is created. Basically, you want to dust the walls of an active coal mine. So just do it. It's pretty simple, actually-if you follow the directions you won't have a problem.

    one could do as a preemptive measurement is to install a catch can

    Seafoam, although many say to use it in the gas tank, I have never noticed any difference. When I have noticed a difference, I put some seafoam into the oil, right through the oil fill(changed the oil about 200 miles after I did that) and I also put some seafoam into a vacuum hose coming off the crank while the car was running(i.e. seafoam was in a cup/container, took vacuum hose off and while the car was running stuck it into the container with seafoam so it sucked it all into the crank(case)) some people say to let it suck in seafoam until it stalls out the car, I would just let the engine suck it up and then turn the car off and let it soak.

    I do not recommend leaving seafoam in your engine for very long. AFAIK there are no actual studies (real ones) done on the effects of seafoam on the internals(seals, gaskets, things that can deteriorate, etc). I am not going to put this into my brand new car because of this. If you want to be a trailblazer go ahead.

    Also, I did the above on a now 15 year old car and it worked great as far as the car was idling bad before and there was definite buildup of carbon causing issues.


    I have no evidence to back any of this up except google the procedures I listed above and it is pretty common. Once again, in the gas tank I dont see how it would clean anything except your gas tank and fuel lines, might even step up the octane lol.....

    Seafoam in the gas tank won't do anything for carbon build up on the intake or valves on a DI engine. It needs to be added into the intake manifold otherwise it just gets injected into the combustion chamber downstream of the intake. Hence why Dyn is calling RD an idiot (again).

    There has been some recent develop about people trying to do induction type services to clean out the carbon build up. Ford has been finding that because when you do these services the engine and exhaust gets so hot that it is wrecking the turbo(s) because on the Ecoboost engines the turbo is quite close the engine and the turbo being fairly small can't take the heat and thus damaging them. As well I wouldn't think all the carbon going through the turbine blades can be good either.

    This video probably explains it a bit better:

    Yep, it needs to be introduced to the engine in the same way it would in a non-DI engine, which is in the head before the intake valves. For vapor lock to occur, a non compressible fluid needs to be placed in the combustion chamber and the engine cycled into the compression stroke. At such time, the piston can't compress the fluid and stops the piston. With a stopped piston, the rod stops the crank, and all the pistons stop. Water is a fantastic fluid to use for vapor lock since it doesn't compress and won't ignite. I am sure you could dump enough seafoam into the engine to cause it to lock, but it would take dumping cans of it down the intake plenum. In the fuel tank, it is mixed with the fuel and atomized in the combustion chamber under the higher pressure of the fuel injector.

    I use Seafoam every spring in my Mustang and found it to make a huge difference in how the car performs when coming out of storage. The car spends most of it's life sitting in the garage where the fuel gets old. For a daily driver using fuels with active detergents, I don't see Seafoam as doing much for it.

    I wasn't asking if it removed carbon build up Dyno...I was looking into whether or not putting Seafoam in the gas tank could cause vapor lock...geez... the whole point was, that Seafoam could help with carbon build up...I was broaching the issue if it might be not be such a good idea, because it might cause VAPOR LOCK...like a PSA kind of...I want to poke myself in the eye with something sharp right now

    Your PSA's are horrible and generally not very valid. You make posts that are literally one sentence despite having multiple ideas (that are usually just guesses or something you think you heard or read about once). The only thing that you've said so far that made sense (and people would support) is that you want to poke your eye out. If you want to make a PSA then make it about something legitimate and try to avoid the stereotypical RDgolfer word-vomit.

    If you're that interested in using it, Seafoam has instructions. Follow them and you'll be fine, just like the thousands of people that preceded you. Simple.

    Oh my god...there have been instances of you being uninterested in facts, and this is proof once again...look up vapor lock people, and ignore this troll, the original troll...the troll who offers nothing helpful, but is ready to drop a dookie down your throat...go back to the other site

    Alright, I'll bite... Going back to your original question...

    and now you seem to have changed your mind about what you were asking:

    As stated above by myself and other posters, introducing Seafoam into the gas tank will not do anything. BRG has pointed out that seafoam can cause vapor lock if you don't use it properly properly. But it's really moot though, because as marc pointed out, there is a seafoam induction service but there are some indications that it could lead to turbo failure.

    Stop...everyone stop...right now...hit the reset button, and if I could, I would erase this thread and start anew right now...there have been instances where putting an aftermarket product into your gas tank may induce vapor lock...including Seafoam...respond now

    There have also been instances in the past where people blew their motor by tuning it. Are you going to issue an incoherent PSA about tuning as well?

    Stop trying to fear-monger because you're completely horrible at it. Just because someone doesn't follow directions and something occurs doesn't mean the entire world should be scared about it. You sound like one of the people that has 90% of all health issues simply because you got on WebMD.

    I do agree with you about erasing the thread, but not so much about starting a new one. #respondnow

    I think the only good thing that can come out this thread is to warn people about induction services and possible turbo failure.

    False. RD may try to poke his eye with something sharp...
