I've been trying to research walnut blasting and whether or not it'd be advantageous to have done to my car. Looking through posts here, it appears that everyone who's had a walnut blast has a turbo'd 335i(x). Is the need for a walnut blast significantly higher with turbo cars? Would it have any advantage on a non-turbo 328?

Thanks

Walnut blasting isn't necessary on the 328i. The 328i fuel injectors are behind the valves, so the backs of the valves get cleaned by the fuel passing by them. The 335i uses direct injection, so the fuel is sprayed directly into the combustion chamber and bypasses the valves. Carbon builds up on the backside of the valves since fuel doesn't flow by them to keep them clean.

+1 what Squark said. Our 328xi's are not direct fuel injected and thus don't suffer from carbon buildup.

Bummer, I was kind of hoping this $300-$400 panacea, makes-it-feel-like-new-again remedy would be useful for us as well.

Just run a couple bottles of techron before your next oil change.

You can give me $400 if it will make you feel better. I've been waiting on $300 of driveshaft parts....

I mean seriously, I've been waiting for over a month for the driveshaft center bearing. Everyday the sun comes up is another opportunity to be disappointed in BMW and lose faith in the brand.

I aint gotta tell ya...i'm waiting for the same exact part.
