Thread killer aka Advanced BMW Repair did the work. Check out the rest of this thread, they are setting up a group buy.
Techron doesn't clean the intake valves because the gas is directly injected. |

Thanks! After cylinder number 3-4 I finally got it down to where I wasnt wasting time and tons of walnut shell lol. The first issue was fine tuning my tools to fit in cylinder 1 and 6 due to space constraints. More cutting and welding lol Second, was efficiently getting the goop out of the intake runners and valve area.
I want to do another houstonites car before I go up to dallas. Heck I want to do a BUNCH of houstonites cars Come on down, folks! I REALLY want to do it tomorrow, if anyone can let me have their car for a friday. Ill offer up a 50 dollar discount (450 total) for the troubles to have it in the morning. Im gonna put a patent on my tools: Thread Killer's walNUT blaster |

Thanks for the tip. I am in San Diego. So you are saying taking it to a shop would do it? I will shop around locally and see how much they are asking for this kind of work.

well, since i dont own a N54 engine, just work on them- I'm pretty tuned into what the general population of N54's do. Nafoo's N54 to ME ran rough at idle. after the intake cleaning, it was a DEAD ROCK SOLID idle. In fact, i noticed the DME going for the first couple minutes of engine operation. I'm sure because adaptations and internal adjustments for smooth running values were all out of whack, now that air was properly being inducted into the combustion chambers. He said he was going to run some logs tonight and see if it made a difference. I know in my professional opinion, it definitely did! |

Did you ever go to BMW of Dallas to have the valves cleaned? Did you pay 576? I missed TK last week or I would have had him do it. |

i don't think the n52s need it done just because the fuel supply is different fuel supply, i think the fuel would clean your intake valves. but for us our turbos shit oil and no fuel passes over intake valves because the direct injection, therefore the build up occers. you could probably use octane booster or techron to clean yours up
