Will it rid the problem the N54 has on carbon deposits? No, will it be better than nothing? Yes.
DIY:
1. Buy Seafoam
2. On a cold engine, pop the top off the vacuum line right next to the oil filter.
3. Start engine
4. SLOWLY pour in seafoam - the engine will run like crap, but don't pour it in fast enough to stall her.
5. When you've poured it all in, immediately stop the engine.
6. Put the vacuum line back.
7. Wait a while. In my other cars, I wait 30 minutes.
8. Start the car. She may not want to start at first, so you may need to tell the ECU she's flooded (Hold accelerator to floor while starting)
9. Once started, drive her pretty hard until she stops smoking.
10. Immediately change your oil (You'll smell it in the oil when you change it)
That's it!  |
I would NOT pour it into the engine. That is how you can damage a engine via fluid lock. You should SUCK it into the engine via that vaccum port.
Also... you would do it on a
warm engine. Not a cold engine nor too hot one. Because you want to be reving the engine as you suck the "cleaning agent" into the intake tract. As the revs fall suck in the fluid. Then afterwards, a few miles after doing the de-carboning - change the oil. Turboladder's DIY write up is good though.
