Walnut Blasting N55 and N54 in Fond du Lac and Northeast Wisconsin, 335xi at 100k+

Bobdudeman and I walnut blasted my e92 (2011 335xi) this weekend. He's a real nice guy, down to earth. He doesn't charge much for this service, in my opinion, but he's really not in it for the money. $180. He has all the tools needed and the know-how on both N55 and N54 engines and doesn't mind if you help. Of course he appreciates a little extra and maybe a 12-pack of his favorite beer (Warsteiner dunkel).

If you do the walnut blast, I would suggest also doing the oil filter housing gasket (OFHG) replacement and the o-ring for the water hose for the extra $30. Buy the gasket and o-ring ahead of time from Amazon or ecstuning. Bob will also do transmission fluid and pan/filter change if you need it.

As for my N55, it had 101,000 miles on it at the time. I've seen pics of N54 intake valves that were much worse at 1/2 the mileage. So the N55 still seems to have the same gunk build-up issue, just to a lesser extent. I have some pics below. Sorry for the quality. It's not the best camera, and I'm far from a great photographer.

Trust me, they're clean as a whistle. Noticeably more responsive throttle. Seems to have more power, but I'm thinking it's more of a placebo effect. Later this week, I'm getting the VANOS recall done, so unfortunately I won't be able to give an accurate estimate of fuel efficiency gains. But I'm SO glad this service is done . It's good peace of mind, and I know it won't be needed for another 100k miles! At least 2 years, right, Bob?

Bob, if you're reading this: excellent job! Since I'm in that area regularly, I'm going to provide you fair warning that you will be seeing my car again... and maybe some beer too.
