Tools/Methods for intake valve cleaning on direct injected engines.

[Junior]

Its time to invest in some new tools or methods for intake valve cleaning on direct injected engines. Using picks and small brushes just doesn't cut it. The process takes way to long. We do plenty enough VW/Audi work alone to make it worth while to have a special machine for this. I've heard of people using soda or shell blasting. Is there are tool or method out there that can use this process and contain it to the intake port without getting material everywhere?

 

What do you guys do?

 

Thanks!!

I have not been able to find the above tool. Several post about people making their own with a small sand blaster. Valvoline has just come out with some products for this issue. We just got them last week and have not yet used it on a car. I will let you know how it works.

We use walnut blasting

What machine do you use? Do you have a way to contain it to the intake port?

We use a BMW OE tool which is a pressure pot. I believe there is another pressure pot sold by German Tool Truck (google him).

We use BG fuel induction service.

Not really related... but I saw this on my FB page.... ridiculous...I guess it would work, but I'd bet you have a better chance of burning down the shop.

For the BMW applications we buy the factory tool which is a cast alum part that has a vacuum cleaner hookup and a small hole to insert a blasting nozzle. Works great.

Ever take a moment to consider BMW advertises the longest oil change intervals in the industry and also is the only manufacturer to train techs in walnut blasting away carbon deposits? Food for thought.

alfredauto,

I know the euro's have been dealing with this for a while, but we are starting to see both domestic and asian GDI engines that have carbon build up issues. The Valvoline product shows some ability to reduce the built up carbon on the valves, but we have not yet used it on a car with significant deposits.

Its a direct injection issue though, BMW just admits the problem. VW/Audi engines are WAYYYY worse and they don't admit its a problem ,they blame it on poor fuel quality. Which makes perfect sense since since the part effected doesn't come in contact with any fuel ever

I used to do that to clean VW TDI manifolds, they are cheap enough new now that its not even worth the time.

 

 

 

On another note, the products like BG and valvoline chemical cleaners might be ok if you sold them as regular preventative maintenance, but if you have a rough cold idle and a misfires already that stuff is not gonna work. Plus I don't want that huge chunk of carbon coming off and being smacked up in the cylinder. Or have it hold a valve open and have it tap the piston. That service might have you buying an engine. The only fix is the right fix, mechanical removal and inspection.
