While I had the direct injected N14 engine out of my 2007 Mini Cooper S, I decided to remove the intake manifold and inspect the valves. I’m glad I did because I found that they were caked up with performance robbing carbon deposits.
In this video I show how I removed these deposits. I also talk about how they got there in the first place.
This video will apply to several vehicles with direct injection engines.
I had some help with editing on this one from Javan Hovind.
