dry ice blasting FSI Carbon deposits

Re: dry ice blasting FSI Carbon deposits

There is a few threads in the fsi tech section on vortex that have pictures of ports running on meth for a good amount of time and it still shows carbon buildup. It seems to help a little but does not eliminate it. To me it is not worth the cost of the water meth set up cost if you are only trying to prevent carbon build up.

Link(s)?

Doesn't bagging on your car eliminate carbon build up? (redline shifts)

Not with the flawed DI setup in the newer VAG heads. FWIW, it's not limited to VAG either, other marques have the same issue.

Bagging on it works on BMW, though buildup removal is still preferable...

Re: dry ice blasting FSI Carbon deposits

Here are a collection of ideas to help prevent the buildup (from another forum): Looks like W/M and a properly working crank case vent system FTW.

Some very easy/low cost preventative options that can help but will not solve the DI valve deposit problems:

1) Use a low volatility and good cleaning oil (cost: additional $5-$10 per oil change)
2) Seafoam, lubro moly valve cleaner, water, etc. through the intake at every oil change (search for dsire thread for a DIY) (cost: $3.50-$10)
3) Regular italian tuneups (VW claims int the engine patent that running at high rpm for over 20 min will burn off deposits but I think it will only help a little) (cost: gas)
4) Catch can (all kinds of flavors out there) (cost: $30-$300)
5) Fuel injector cleaner in the gas to deal with fuel injector deposits (will not help with intake valve or intake deposits) (cost:$5-$10)

More difficult/expensive but more effective "treatment" options. These also help but do not completely solve the problem:

6) BG induction service or similar (cost: $135-$250?)
7) water/meth injection (cost: ???)
8) remove intake manifold and clean valves every 50k or so (cost: ????)

Some one-time-fix-the-problem options:

1) bypass pcv and route to exhaust (search for saaber2 thread "bypassing pcv") (cost $125-$175)
2) Run a catch can that vents to atmosphere ((may increase build up acids in oil due to lack of vacuum in evacuating crankcase gasses (but that is unknown)?)? may have smell or freezing issues?) (cost: $300?)
3) Run a "down tube" or "road tube" that vents to atmosphere ((may increase build up acids in oil due to lack of vacuum in evacuating crankcase gasses (but that is unknown)?) (cost: $25 -$50)

Apparently not

^^^your list haha doesn't have the best solution, keep reading...

carbon buildup only exists in canada/usa, cause they are using old ass 502 spec oils still lol

read through it all its interesting, especially page 19

https://www.lubrizol.com/EngineOilAd.../LowerSAPS.pdf

and here's the VW list of all their oils

the oil i used was castrol slx pro ll03 you can buy from any vw dealer (its their tdi oil), yes every vag dealer in europe uses this same oil in the newest gasoline/diesel engines

Not sure how you get that Carbon build up only exists in North America from that 8 year old presentation?? Low and mid SAPS oils are available in Canada and the US, Amsoil European formula, Shell Helix Ultra, Castrol Elixion to name a few. I am sure that if all those Carbon Cleanings that have been done under warranty could be stopped by changing the oil then the VW, MB, Audi, BMW, Volvo etc would have jumped on it a long time ago. Also what are all the carbon cleaning for DI services like Terra clean in Europe charging people for if there is no carbon buildup issues? Also some of the new European specific Engine models have direct injection along with multiport injection designed to combat carbon buildup.

Best solution is to start with a clean engine, new or fresh after a clean, and start with some preventative solutions. Number one fix your Crank case vent system to stop oil from entering the intake system. Number two would be have some sort of continuous cleaning. Hot steamy water does the trick especially if it is mixed up and atomized with methyl hydrate.

Re: dry ice blasting FSI Carbon deposits

go for an oil change in your gasser at the dealer, tell me what oil they put in

they do more paid carbon cleanings than warranty ones don't worry

Pretty sure the 2.0 FSI engines are 16v. Looks like a 20v to me.

It just looks like Martin's post above of his FSI has 3 valves. Unless the valve on the right is a large hole in the head that is.

Re: dry ice blasting FSI Carbon deposits

People posting pics of valve on meth are not the same as a fsi car. In the standard injectors shoot gas over the intake valves and as long as you are using a good fuel and do not shoot to much recerc back your intake valves will stay clean. I have taken numerous intakes off on higher milage engines that show no build up.

Re: dry ice blasting FSI Carbon deposits

No not fsi. Still clean as hell. There was far more build up before.
