Direct Injection carbon build up

Just thought I would pass along an article that I read in one of my trade magazines, Motor Age. You cant view the magazine unless you have a subscription but if you go to www.searchautoparts.com and type GDI into the search engine it pulls up the article. It has some very good information on the subject with GM and Ford both adding comments. Thought some of you would enjoy it. Tracey fell free to comment on the article as you probably have more knowledge on the subject than the authors do.

Interesting article, thanks for sharing.
I wonder what the process is to clean the valves from the intake port.

Apparently there is a kit to clean the deposits from BGCompany, its called the direct injection cleaner, and it comes in 2 parts. Has anyone used it?

The only way I can see to do it is like we used to do in the 80's when i worked for Nissan. We removed the upper plenium and actually had a blaster that was filled with crushed walnut shells which did a great job of cleaning them and were soft enough that they caused no problems. Wow how far we have come with technology and we still have the same problems that we had 25 years ago.

If you scroll to the bottom of this page: http://www.bgfueltest.com/?page_id=15&pid=58

You can see how they pour a solution on to the cylinder and using a brush they remove the deposits, but it doesn't say if they vacuum the residue or just start the engine...

That would be my concern. Whatever you break loose has to go somewhere.

Edmunds article

Paragraph from Edmunds article on the Cadillac 3.6 DI engine on carbon build up which is the same engine in the Camaro.

All Engines Not Designed Equally
Many automakers’ gasoline DI engines do not appear to exhibit any carbon build-up issues at all, however. Digging into online threads about Cadillac’s 3.6-liter DI V6 in its popular CTS lineup does reveal some owner concerns about carbon build-up, but it’s difficult to find even a single report that any build-up has actually occurred – a record that is notable considering that Cadillac has sold more than 200,000 CTS models with DI V6s
