induction cleaning

[blkspeed]

has any one done this yet i figured it should be very helpful since these cars have bad carbon build up

im getting this done with new denso plugs i expect big results

[mortimersnerd]

I'm guessing this does little more than clean the MAF. $5 can of electronics cleaner at Autozone will do the trick just fine and can make a difference. If this made a huge difference we'd all be doing it.

thats why i posted this to hear everyones comments

i have a family friend mechanic who highly recomends it due to being running too rich at idle also adding to it is very low rpm at idle and poor mpg not sure about power since ive only had the car for 4 months now

I use Seafoam in all my vehicles. Not yet in the MS3, but probably will with the 60k mile maintenance. I like this video the best:

Problem is, mate, our cars are direct injected and are using fuel pressures up to 2000 psi. You can't just use any old rubber hose setup for 40 psi port injected cars on ours.

[cymx5]

I'm not as familiar with direct injection. Am I missing something here? You can still put Seafoam into your gas tank and a vacuum line.

The fuel mixture is closed loop at idle and it is controlled/monitored by the ECU.
If it is too rich, the MIL would be on.

I did this a few weeks ago....smoke, smoke, SMOKE!!!

so this would not work or it would hurt the car?

and i thought sea foam would eat the turbo seals?

First of all, please read before replying. I'm not talking about pouring Seafoam in the tank or, hooking it up to a vac line. I'm replying to the OP's idea of doing an in-line fuel injector clean. That won't work on a DI car because the automotive systems that do this are set up to run 40 psi port fuel injectors not 2000 psi direct injectors. If you did hook this up somehow, you'd blow it wide open and spray vapourised gas all over the shop. (boom06)

...and, on the Seafoam front, our cars are 2 or 3 years old, unless you left them idling all that time using Mexican gas, there's likely pretty much 0 deposits in the engine. The smoke the Seafoam users are seeing is Seafoam itself cooking off.

sorry i didnt know who you were replying to. and who is op? i didnt see a member name in the topic

sorry im confused but ill ask again so i can get it straight

so the bg system in the youtube video wouldnt work on our cars?

if so im shocked if thats ture because my mechanic is wanting to do this to my car

well the cel code said running too rich at idle

OP=Original Poster

There are two kinds of systems, ones that line in to the fuel system and ones that work like a can of Seafoam hooked into a vac line where cleaner is drawn into the engine by engine vacuum or moderate pressurisation in the can.

From the looks of the ad, this system is the former, which is the most effective way to do it. However, also from the ad, it looks like a port injection setup which won't work on a DI car. I could be wrong but, that is what it looks like.

Has your mechanic any experience with DI? It's pretty new to the car world. It's been on diesel big rigs for decades and in aviation applications since the 1930s.

[blkspeed]

im not sure ill ask him tom. and see if he knows or not

thanks for the help

[blkspeed]

well i talked to my mechanic and this induction cleaning wont harm our engines im getting it done tom. with my denso spark plugs so ill post reviews tom. nite

[Saskatchewan17]

Put the plugs in after... I would just seafoam it. 1/3 in the gas tank, 1/3 in the brake booster, and 1/3 in the crankcase. Change oil 50 miles later... ta-da.

Also... how many miles does the car have? I don't think you need this service at all... just throwing money out the window.

[blkspeed]

its a 45,000 was at 400 rpms at idle and the induction cleaning with denso plugs are done its now at 800 rmps at idle. i cant wait to drive it tonight

[cymx5]

Very cool. That is great news to hear and I'm happy it worked so well.

This is where you would be so wrong my friend. Our cars need it more because we are DI.

Linked to the cause of all this.. EGR and poor PCV system. We arent the only ones struggling with DI on this. Seafoam..do it. Running meth helps to prevent this, but not a fix.

That 100,000 miles on the GLI??!! Of course there's some deposits built up. Especially since it's a notorious VW problem that they hate low speed running and load up super bad when you do. And the deposit level on that 50,000 mile 3 doesn't look that bad, nowhere near enough to freak out about.

Given the general level of maintenance American-driven automobiles receive (namely, nearly none until they break) it's no surprise to find deposits, most people don't change their oil nearly often enough and that's a major cause of deposits.

There are far to many potential causes of deposits to blanket say we all need to Seafoam our 2 year old cars. It's all about maintenance and treatment. If you've been using your 3 as a taxi or police vehicle or as a delivery vehicle for UPS and, failing to maintain it, maybe you should get at this but, given good, normal treatment/maintenance, it's probably premature for most of us.

I am old enough to recall when decarbonising an engine was a normal service. This meant a complete teardown and hot-tank at specified intervals, if you can believe that.

This is what Seafoam and other products were designed for, not for modern, EFI and computer equipped cars. This doesn't mean deposits don't form and affect performance but, it's ALOT further down the road than it was in those days.

Nonetheless. There is still a problem with DI cars and our PCV system. If you do seafoam once every 15k, if will definately help out a lot. I cant definately see how the build up could rob us of power. All that mass adds weight and restricts flow. Man, mazda needs to come out with that PCV system fix.

[Darth Vader]

I think PtP might have already done that with its restrictor. I haven't seen even hints of any build up in the motor yet, since I put that in. 'course I only have about 17,000 miles on the car ;) but, I do have the deadly downpipe and race pipe combo that seems to be the cause of most PCV related upset. I did put it in BEFORE I saw any turbo smoke :eek:

[blkspeed]

sorry i didnt post back sooner but i noticed big change when im at 60mph plus. the rpms where at 800 now dropped back to 500 and my cel came back on donno what the code is but i think its just my ms cai... i still havent put the air flow straightener in

[cymx5]

dur.

[Darth Vader]

No. You don't understand. There are TWO types of setups: The setup you just described uses engine vacuum to draw seafoam or whatever into the engine from either the ATMO side, in front of the turbo (not recommended, in my view) or, the VACUUM side, after the turbo. There is no way what you describe will occur, since it's only only atmo or vacuum pressure levels that exist there during idle/no load running. Even if you lined into the car's vacuum lines AFTER the turbo there's virtually no engine load at idle so no boost is produced. This system will work just fine on ANY car, fwiw.

The problem is with the other professional kind of injector/engine cleaning system which uses the FUEL LINES as its entry point. The fuel in a direct injection car is pressurised by the fuel pump to between 400-2000 psi under varying loads. The port injection cleaner setups are only rated for ~40 psi or so not 400, much less 2000.
