Post VAC Walnut Blaster Service | 135i/335i/535i Intake Valve Carbon Cleaning

Walnut Blaster Service for 135i/335i/535i

Price: $425 (people say dealers charge $650-$800+)

About VAC: http://www.e90post.com/forums/showthread.php?t=593996

About VAC's Walnut Blaster Service:
We use factory BMW tools to perform this job. These tools ensure the job is done right first time and there is no mess. The intake manifold is removed and all ports are cleaned with BMW factory tools and BMW approved walnut shell media. The manifold goes back on and everything is tested/checked.

We chose our technician Frank to perform these jobs - he is a former BMW dealer master technician who had the pleasure of being the go-to guy at his dealership for S62 (E39 M5) carbon cleanup jobs. (google it) He is now the go-to guy for N54 jobs ;-)

Why do you need this service?
See the pics below. All BMWs with direct injection will have this problem. This buildup can cause:
-driveability issues (stumbling, odd throttle response etc)
-loss of power
-inconsistent idle
-emission concerns

FAQ:
1. How do walnut shells fit in my intake port? They don't ;-) We use BMW approved walnut shell blast media which is more like fine powder. This is ideal for cleaning aluminum.

2. Will I start doing 70mph rolling burnouts after the Walnut Blaster service? No. Depending on how bad your buildup is, you may feel an immediate improvement or just a slight improvement. Rest assured that you will save yourself a headache down the road - as severely gunked valves are bad.

3. Can my buddy spray it with CRC and get the same results? No. This buildup is pretty stubborn, so the media blaster+walnut shell is mandatory for a proper job. If BMW specs this service with a media blaster, one can assume this is the best way of doing it. If they could do it quicker, they would - trust me.





As it arrived:


Ready for work:

That is a very nice service VAC! I am sure you will have PLENTY of biz with the CB on the N54/N55 motors.

PS: I'd love to see a video of the process.
