If you want a cheaper kit, AEM and Snow Performance both make decent kits...they're hard to tune correctly for the fullest performance benefit though. But seems like you just want it for keeping the intake tract clean...so they'll certainly get the job done.

However, while water/meth injection will do wonders to keep everything clean...its not a simple mod in my opinion. I would never run a meth kit without getting my car tuned for it. It's definitely a performance oriented mod, versus a keep-your-intake-clean mod like an oil catch can. The fact that it keeps everything clean is merely a side benefit of it.

I know this will start some crap.

Give Jan a call at RMW. I believe he has a setup for the R56.
Also PM "big howe" here on NAM. He's the aquamist man here on NAM and has tons of info.

Thanks Thumper...I read your comments on tuning the car as well as setting up the aquamist. I'll take that into consideration.

Trying to digest all of this, and wanted feedback on a question:

I drive 43 miles each way on my commute, and depending on traffic conditions there are decent stretches of "spirited" driving (amazed I haven't gotten a ticket yet). I also tend to take her out once a month or so for a speed run up a local mountain road.

Given this, is carbon buildup still something I need to fret over, or am I doing enough "Italian tuning" to mitigate the problem? I use Chevron premium grade all the time.

Regardless, I'm going to start using a fuel system cleaner now (never used it before). I just need to determine (a) should I get a oil catch can and (b) do I need to Seafoam-tream my baby...

Does anyone know if its alright to use seafoam during the cold climate season, aka. Now, Boston area, its about 35 right now, will probably be about 20-25 when I get home tonight
that and if once I use it do I need to change the plugs? I've seen that on here a couple of places and dont really want to make more work for my self? should I just do it through the PCV or should I put some in the tank? has anyone seen any results from that? if in the tank is it advislble to change the fuel filter too?

2008 MCSa 15600 miles

Your feeding the seafoam into a hot engine so unless your in 60 degree below conditions(as it states on the can) you shouldn't have a problem.

Fuel tank additives do nothing on the direct injection motor. Read this thread about additives and direct injection.

How many miles on the car? Did my first seafoam at 30k miles and seemed to do wonders. The car was starting to ping pretty badly around then...the SeaFoam treatment cured that. (Could have also been exacerbated by a faulty high pressure fuel pump that I had replaced at the same time...) Regardless though, I think making it part of your 30k service is a good thing to do.

Ok I had a rough start a week after they cleaned the MINI out. It seem to misfire and run rough for a few minutes, but once warm it was okay. In fact it never happens while its been garaged overnight and started. Only when it sits out.

Any guesses? Should I take it back to the Stealer?

They tend to do that when the High Pressure Fuel Pump is getting weak.

Ok should I just request to have it replaced? Cause I'd hate to have them diagnose and find nothing wrong...

I have been looking at the various BG products (BG ISC® Induction System Cleaner, BG Fuel Injection System Cleaner, BG CF5, 44k power enhancer, ....) but I can't figure out the real difference between them.

Gas additives may help with deposit prevention or maintenance of a recently cleaned engine, but there is no substitute for the PCV hose direct cleaning of the valves because little gas and thus cleaner gets on them due to the direct injection design of this engine. Any of these chemicals will do a great job removing carbon from the valves and intake manifold system thru the PCV hose method. In addition the chemical is not diluted by gas, can work full strength and achieve faster results.

"there is no substitute for the PCV hose direct cleaning of the valves"


Do you mean add this through the intake hose? I have read where some have said to do this with Seafoam....

Whats the difference....BG44k...Seafoam...etc.?

I think there is a sticky describing the procedure, it may be one of the first posts to this thread or under How to do it somewhere on this site. The procedure is more important than the chemical. Many many folks swear by Seafoam. I tried it and thought it was better at creating a smoke screen than removing carbon and had better luck with Trimaxx 2000 from www.carfood.net or Lube Control Fuel Power 60. I am sure RedLine or Techron or any BG product would work just as well thru the PCV hose. See the fuel additive threads at www.bobistheoilguy.com

I am now having an issue with the carbon buildup in my car. Mine is an '07 MINI S with 30k miles on it. Dealership has had the car for literally 3 weeks. They cleaned the carbon buildup from the engine but they still say the engine is not turning over corectly. They think it might be the fuel pump.

Any way a CAI could cause the fuel pump to go out? That and an Alta boost tube are the only engine mods I had, and it kind of has me worried after talking to a good friend of mine that works as the service manager at BMW.

i took my mini today after a check engine light going on and off and now its just on! Ive been having a lot of trouble starting in the mornings only. It would take 4 trys and sound horrible and shoot smoke out of the exhaust. So my SA said it might be the hpfp but then I get a call later today, and he said my engine is full of carbon build-up!!! So ill see if that fixed the problem when I get it back tomorrow.

And the beat goes on. Watch for MINI to come up with a change on these engines. The shops are full of cars with this problem.

What have you seen and heard from shops about prevalence of the issue?
