Walnut Shell Blasting Results - 49k miles
My car has 49k miles on it and I decided it was time to get rid of the carbon buildup. There is a local board member, Rob, that I found on the e90post boards (N54tech link) that does this at a reasonable price and lives right down the street from me. He has done work on quite a few cars on the boards and everyone has spoke highly about him. I had him replace the Oil Filter Housing Gasket as well that I was told was leaking at my last oil change and would cost $600 to replace.
Here are the videos Rob took of the job: before showing all the carbon buildup - middle comparing the dirty and clean - last video showing the all clean - Here are a few pictures he took of the install: View post on imgur.com I drove the car about 20 miles tonight, and the acceleration feels a lot smoother and when doing a pull, the top end feels stronger. Those were my initial impressions at least. As far as Rob's work, in my opinion I think he did a top notch job and he has great communication skills. Unfortunately for us (or me,) and fortunately for him, he starts school again soon, so his availability is limited. Anyways, I feel walnut shell blasting is a necessity for these engines and I hope everyone is able to get it done at least once during the ownership of their cars just to feel the difference.
