Is this process done on both the intake and exhaust valves?

Only on the intake valves. We did some testing on the exhaust valves of some cars and the benefits where minimum if any. The burnt fumes flow over the valves and very little actual build up occurs.

Hey all,

I would like to make use of this service, but will it affect my motorplan?

There is no way to detect that any work has been conducted beside the fact that the valves are clean. In turn BMW will never approach the customer in this regard as it is like they are out right admitting the vehicle has a latent design problem. We use OEM gaskets when replacing the manifold and all the pipes and connectors are put back into place where they belong. 8/10 times we find the dealers have done choppy jobs especially if the car has had a fuel pump or injector recall.

Looks like the S3 and VW GTi's has this "build up" problem. And yeah...I drive one...! :bangdesk:

What if you had to offer us a "loyalty card". Say get 1 free after every 3rd or 4th carbon clean?:biglol:


Its just that if you had too do this every 30k, it can become expensive.

You'll save that money from a reduction in fuel economy.

My car dropped by 2,3L/100km after the carbon clean (will still write a quick review soon)

If you save only 1L/100km you actually getting it for free at 20,000km. You then have all the benefits. I tell all my customers to use the calculator and decide when to come. With a lot of car owners not having the car from new do not really know how the car should be and take it for granted.
The loyalty card is on the cards for customers that come in within the recommended return mileage as its less work for us second time around.

Hows these nostrils: Naturally aspirated car, feels like its got gas now. The RS4 is a popular car for Carbon Doctor. We have six under the belt.

Really impressed by this but scares me to think how many drivers don't know about this. What's the potential damage that his could eventually cause to an engine ? Could it stop a valve from closing properly ?

In the long run the valves will start sticking. I have seen a few videos on youtube showing that.
If a piece of carbon dislodges at the wrong time you will loose all compression in that cylinder. I also think that on some cars it will affect the valve stem seal.
I will post a picture of a S3 we did yesterday and the one valve is virtually completely blocked when in the open position. The boosted air found its way through the opposite side. I didn't have time to scope the piston top or the bottom of the valves but I am sure that cylinder must be very nasty inside.
The biggest damage is in the pocket though. Fuel consumption becomes so bad and the car so much less responsive. Problem is most ppl buy cars used so they take it for granted thats the way the car should be.

This is a pretty high mile car we did recently. In the first pic you can see the left hand side valve is completely full of carbon. I will post a picture of the valve open to see that there is only 1.5mm of opening left for air to travel through. The interesting part is check what happened to the right side valve on the same port. It looks like the boost has pushed the carbon right into the combustion chamber. Its anyone guess if it was a chunk or or bit by bit. Lucky it didn't get caught in the valve seat because there would be no compression on that cylinder.

When I pulled the intake off my RS4 I couldn't believe what I saw. I did my carbon clean myself,and the difference in the car was amazing. Any direct injection engine is going to suffer from this, so if you have a direct injection car, you will 100% have this issue. This is a community service worth having! :biglol: Just sorry I didn't think of it first!

Well done George!:thumbs:

Did you use the carbon soaking over night method? or just a lot of carbon spray?

Food for thought. If the carbon spray seeps into the combustion chamber it will wash part of the side walls. Existing good carbon has built up and the rings have bedded in to it. If it leaks down part of the side wall (similar to a water on glass) the ring will not seal and the car will start using oil or in the worst case lose compression. There goes our first trade secret hehe
