Can someone post a simple picture of where on the N54 I can easily and safely vacuum in some seafoam? I want to do a quick clean before I install my intercooler and I just cannot figure out what is the correct intake/hose.

I've done this before with other cars, but for the life of me, I just cannot figure out the right hose.

Where is that?

Vacuum line from the diverter valves...it connects to the intake manifold on the right side underneath, near the the throttle body. If you have an aftermarket intake with the airbox removed its pretty easy to spot. Otherwise you might just want to use an extension onto one of the existing DV lines. Mr. 5 has a pretty good DIY somewhere in the Turbo section IIRC.

I am having trouble with clogged injectors....I know it doesn't seem probable with 1500+ psi pushing through the lines but I have replaced 3 out of 6 new injectors that BMW installed under warranty and each time i replace one, I get a misfire code on one that I didn't change. This tells me that the injectors work... but just not to capacity. They are new so they must be clogged. Not sure if bad gas or octane boost has created a build up in the injectors but I can't afford to keep replacing them. TO THE POINT.

I Have heard that when doing seafoam that you should rev the car but not over 2K. My misfires are coming around 3K. The info I have read says that if you rev above 2K that you might foul the plugs so I have refrained from doing that but I am wondering if the position of the injector head has to do with whats actually being cleaned.
