How does this work and do the shells all get vacuumed out or something?

Thanks. Always good to learn about something new, I'd never heard about this until this morning!

The mechanic I talked about in the other thread does the walnut blasting on DI turbo motors. It's expensive simply because it is so labor intense.

I never realized you could do the blasting with the intake on the vehicle. Interesting procedure for sure.

I doesn't seem like too much work if you have the right tools, I think I'd just do it myself.

Why not a device or a port permanently installed downstream or in the outlet of the catchcan to spray the cleaning agent at regular intervals such as every 10,000miles?

Most manufacturers don't want you spraying anything down the throat because it will go through the turbo and can cause trouble with the vanes. If a big piece of carbon breaks off during cleaning, it would also go out somewhere, and could mess something up. Also can cause fueling issues when the system isn't metering an amount of fuel that it's coming in from another source.

I perform this job quite frequently at work. All of them chemical cleaners and tools we have tried seem rather ineffective. The best method we have found is walnut shell blasting. Requires removing the intake manifold but is by far the most effective. An oil catch can will help but buildup will still become an issue at some point. Vehicle probably has around 50k miles on it.

Looks like it will become a necessary maintenance step with our vehicles. Do you use BG products at all? I'm curious if the BG injection service would help prevent this build up in order to postpone the need for walnut shell blasting.

If it goes in the fuel tank, no. No fuel goes past the valves on this platform. If it goes in the oil, I still doubt it because if it was as easy as putting something in the oil, it would already be in the oil since this is a big thorn in the sides of most manufacturers.

Oh yeah, I think the service I'm thinking of uses a pressurized bottle and sprays directly into the intake manifold through the throttle body. So it would only pass over the valves and then be immediately exhausted through the combustion chamber.

Which then goes straight through the turbo impeller, so any carbon would go through the the exhaust valves and into the turbo...

They are also worried about the EGT's, too much un-burnt fuel can cause the turbo or catalytic converter to overheat.
