Carbon Clean = Shit SO FAST [RESULTS]

[yayjohnny]

So, after a dyno day and very disappointed results.
I felt the urge and the need to do this carbon clean as I am at 97k miles and have no idea if the previous owner ever did it.

First off, thanks to DRAKLORE and his awesome DIY's and explanation and the STaSiS k04 installation guide.

RESULTS:
The results is phenominal, YOU MUST GET YOUR CARBON OUT OF YOUR ENGINE.
The throttle response is a HUGE difference, and my RPM seems to go up way faster.
Ignition now is so much smoother. It used to take 3-4 chokes before the car would start, it would take half a choke and the car started.
All in all, the car is WAY smoother and quicker.

Just a few heads up for those who want to do this.
1) Definitely do research, and have the guide ready. Look through multiple threads and learn the comments and etc. KNOW WHAT YOU'RE DEALING WITH
2) Have the right tools! Make sure you have the
-Triple Square M5 screw
-a magnetic pick up tool because nuts and screws will fall off
-air compressor (or just the compressed cans for keyboards - grab a shit ton of them) / or vacuum.
-seafoam and/or brakleen (or carb cleaner).
3) When you re-install the intake manifold after you finished cleaning your valves, you wanna make sure your BLUE o-rings are ON all four injectors otherwise you will have fuel leak, which means u gotta re-do the whole thing again.
4) BEFORE you start your car when you finished installing and double/triple/quadruple check everything to make sure the bolts and nuts are on tight, and all the sensors are plugged... Turn the ignition onto ON, and wait about 1-2 mins, then off, then ON. You should repeat this 3-5 times to let the fuel flow through the car and fill up the HPFP and the Intake Manifold/Fuel Injectors, otherwise your car won't start.
5) Be prepared for a long work job, this took me and my friend a loooooong time.
6) Valves will either be OPEN or CLOSED. Me and My friend used Seafoam for the OPEN valves, and Brakleen for CLOSED valves. The closed ones are so mcuh easier to clean cuz we filled up the cylinder with Brakleen, and let it sit for 5 mins, then scrubbed with our long flathead to get them loose off the valve, then dried it up with a shop rag, then used an Air Compressor and blew the poop out of the valve.
I think you can use Brakleen for the OPEN valves as well, but we were a little scared, so we used Seafoam.
You definitely need to get down and dirty with your flathead and scrub and try and dig them out as best as you can.

The job is all labor if you have the right tools already, and one or two cans of the cleaner, and air compressor or vacuum to suck out all the carbon stuff

Audi just needs to step up and admit to this problem once and for all and warrant it!!!

[DRAKLORE]

Hey man I'm glad I was able to help! Sorry I wasn't able to reply to the pm until you prob figured out about the O-rings.

I think most people including myself make that same mistake the first time lol, but practice taking off the mani makes perfect lol

Yes, because i'm SORE EVERYWHERE and it hurts

[DRAKLORE]

But now you see that seafoam and BG are just band aids.

Dude, thank you so much. Spending $20 and bunch of MAN is better than spending $600 or $700 elsewhere.
Time to buy more mods ;) loljk.

Yeah, after installing and re-installing and installing, definitely can pull the manifold off way faster

[ericpaulyoung]

Step 3 very important. The blue o-rings have to be ON THE INJECTOR beneath the metal step piece. Ask me how I know.

Not fair, you busted my balls for messing up this step, but you only slightly tease yayjohnny! What the heck ;-) hahaha

[DRAKLORE]

I've realized my "walk through" isn't perfect lol

[ericpaulyoung]

I understand now that by this point in the process you are so damn excited to get it back together that you can't read the transparent computer ink on the part where you are supposed to check the o-rings.

PM sent!

Im at about 56k miles and add fuel system cleaner every 3k miles, plus I use 93 everytime at a good gas station. Do you think I would benefit from a carbon clean at that many miles? Plus I often enjoy reaching the rev limiter

[DRAKLORE]

Hey I added the O ring note to the 20$ carbon clean thread

Any way we could get the before/after pics in there, yours are some of the best examples I've seen yet :-)

[BoSNiaN]

How did you actually clean the valves? Using just brakleen or did you physically scrub them?

If there is residue blakleen, will the engine burn it off, or will it cause problems?

[DRAKLORE]

Bosnian- read the walk through where that question has been asked and answered. :-)

[Charles.waite]

Hey OP, mind linking Shane's DIY in the first post? Would really help for people searching this in the future. I know where to find it, but you'd be surprised...

I think stupid people shouldn't take their engine apart. ;-)

The man makes a good point! Touche...

[yfzcentral]

Good write up! What part is this?

[ericpaulyoung]

^^
That is the fuel injector. You can tell it needs lots of cleaning.
- Eric

:-)

[DRAKLORE]

^ i shouldn't be laughing lol


Wasn't there a debate on if that piece is needed ?

[ericpaulyoung]

Ya, I was going to take mine out when I slap on the K04 and S3 injectors, then delete my flap motor, but like most of my ideas, you guys basically mocked me out of making a foolish mistake. Audizine is like my conscience, keeping me out of doing awful stupid things to my poor car. ;) I am still thinking of bending the blades down and grinding it to match my valve contour, so that the air flow is more streamlined. I will just have to see how I am feeling on the day I put on the new turbo.

[CorneliusRox]

I'll probably do this when I go through and kill my PCV. and vent to air!

Wait so thats not the injector?!

[yayjohnny]

I wish I took more pictures, but oh well.

Updated the first post with the links to the DIY.
Updated a few notes that I just thought of, like ignition is way smoother now. and also before you start the car after clean, you need to turn the key onto on for a few minutes and repeat a couple times before you actually turn on your car.

Valves will either be OPEN or CLOSED. Me and My friend used Seafoam for the OPEN valves, and Brakleen for CLOSED valves. The closed ones are so mcuh easier to clean cuz we filled up the cylinder with Brakleen, and let it sit for 5 mins, then scrubbed with our long flathead to get them loose off the valve, then dried it up with a shop rag, then used an Air Compressor and blew the poop out of the valve.

Yup, it is. I was going to do the injector delete mod that is so popular in Brazil. Or is that the Brazilian I am thinking about??

I just googled Brazilian with safe search off. Are we still talking about cars?!



I'd love to hear more about this injector delete mod!

BEST gas mileage I've ever gotten...

[Mister W]

Fu*k i'm scared to mess with that. As it look simple, if you mess up, it could cost a lot.
How much to do me, i mean do my valve ? ;)

[saizero]

Me thinks it might be time to check how bad the valves are caked up with carbon. Power seems to be down and I can't get MPG better than 27 no matter how hard I baby it.

I wanna see some before/after dynos to see how much power the carbon steals!

[yayjohnny]

I have before dynos already, which is literally 1 day previous to the carbon cleaning. (reason why I even decided to do it in the first time)
Will be going in for another dyno this Friday to see the difference, and then I'll post the dynos

Just curious, how much power were you making before you did the carbon clean?

[mcpcartier]

Can you do the cylinders with the valves closed and then just turn the crank to get the remaining cylinders in the closed position?

[Khaotic]

Yupp.. This is the first I've read about that didnt Works both ways apparently, just that with this way you gotta be careful not to drop any "chunks" into the cylinder I guess.

Yeah, most definitely. just copy the links :)

[DevilS4]

It's amazing how dirty these engines get. I'm cleaning mine this weekend, hope it makes a big difference.

[fly300kts]

I wish I took more pictures, but oh well.Valves will either be OPEN or CLOSED.

I have a question: why you dont engage a gear and bring the valves for each cylinder, to a closed position?

Because that would make it too easy. :) My back hurt for days after due to all the leaning over and scraping...
