Anybody know a good place in NJ/NY that's offers walnut blasting? Really want to get this done on my 2006 GS for carbon buildup, thks.

 

where is carbon building up?

 

Concern about buildup in the intake, I have an 2006, read that walnut blasting is the way to go. I can probably go the BG or motorvac route but I think the walnut blasting would be more thorough, Thks for the help

 

stock intake or aftermarket?

and do you mean in the throttle body or intake pipe itself? like where exactly.

just trying to see your options

 

Yep, everything stock, meant the intake valves

 

are you take the head off? or cleaning while its on the car?

 

To be honest, not 100% on the process, I read that bmw owners has had success with walnut blasting cleaning up the carbon buildup deposits in their direct injection engines. I'm definitely not doing this myself so looking for a shop that would offer this service for Lexus owners, thks

 

Im a BMW tech and Im familiar with walnut blasting. Youll take off the intake manifold and blast the valves and then just clean up everything else.

 

Yep....just what he said...call a local shop that specializes in BMWs...tell them what you want and they will let you know if they are up to tackling the job.
