depends how you define "bigger"

iirc high school chemistry...

going from left to right elements have more atomic mass, so oxygen wins

but carbon has a larger atomic radius - size, so a win for carbon

Interesting, things have moved on since my high school chemistry lessons from (way) back in the day - I would had assumed the outer valance shells to have been the same size - or slightly larger, if anything, due to a larger nucleus.
[edit] More protons, stronger attraction to the electrons, maybe? Anything on isotopes being the same or different?

These are my thoughts and opinions - sometimes I'm wrong, but not often ;-)

As previously suspected. Hydrogen carbon clean does sweet FA for intake carbon build up on a direct injection motor.

Any of you looked at the Seafoam stuff, seems to be quite popular in Yankland?

asked an experienced mechanic about this, reckons it's not good but mechanics will do it anyway if the customers wants the cheap option, it does apparently do the job however it may also reduce reliability and longevity, in particular the around the seals - an example I heard was a customer with a holden commodore who came in wanting the quick cheap method - sea foam was used, 10,000km later the customer came back complaining that the engine is using oil

I disagree, i have seen a  gti 's intake after having a pre-chem treatment and hydrogen treatment and it most certainly does
have a cleaning effect on the  throttle body,combustion chamber, valves,injector face,spark plugs  and oxy sensor.

Got a cheap endoscope and had a peek into my intake. Looks like I'll be giving it a clean soon. It looks pretty dirty in there.
Are you opening it to clean it? can you do a before and after pic?

I am planning on it yes. I will document my experience. At this point it will probably only happen over Christmas though when I can afford to have the car off the road for more than just the weekend.

in Auckland , mat and clint barber specialise in this process.
(king st grey lynn.  www.carbonclean.co.nz  ph 021  999 338
Wellington , john on 027 733 7270
the engine is  done in situ while running.
some require a chem pre treatment followed by the hydrogen / oxy treatment.
A few still need manifold removal due to there initial level of contamination however,
from there they can go on a  maintainence program using the hydrogen treatment.

insofar as the periodic table goes  hydrogen is the smallest atom being no.1   carbon is  no.6.
that said the hydrogen softens up the carbon and allows it to be removed by gas flow inside the
engine.
There has been numerous dyno tests been done by  matt and clint barber proving the concept.
I gather Audi a few years back were running hydrogen through some of there engines at Le Man.
upon achieving a podium finish the engines were opened for inspection and found to be near spotless !.

I realise this is an old topic, but I wonder if Subaru have a product to help with this.

Subaru have an upper cylinder cleaner product that is a specified part of the maintenance schedule for the turbo'd engines (not sure about the NA's). It is a foam that you spray into the intake.

I bought a can of that stuff. The sales people said the mechanics there go through loads of it. 
It did blow some stuff out the exhaust but my car tends to do that at start up anyway as it is catless.
I'm not sure if it made things any better or not really. I don't think I'd get again. I'm more likely to just do a manual clean myself if I feel the need in future.
