Just ask if you have anymore questions or suggestions where things can be done better.

Thanks for watching and HD is available. (Video updated)

Great DIY! Thanks!

If you're doing it for the first time, I suggest removing the throttle body before the manifold. This gives you full access to the electrics box and you can yank it off much easier. After the manifold is off, unplug the TB and you can put it back together while off the car.

I cannot see the video yet, but if you explain how to turn the crank to get the valves TDC on the 6AT, i congratulate you because that has been the only reason I have not tackled this DIY yet. Many thanks! Great!

Yup it's in there, pretty simple once you see how it's done.

Yes, very very ugly. Let the carb cleaner sit in the valves for a little to help with the process.

Hey everything is going great (my valves are insanely and I mean insanely dirty) Question is I spared some carb cleaner in a open valve thinking it was shut (that dirty). Is that ok? I know I heard people saying you need to change your oil after this.

Should any gaskets be replaced or screws in the process?

Some people will say manifold gasket but I've reused mine 3 times and no issues.

Great thank you so much....

P.S. You can also leave radiator fan and push the car if it is MT on the Gear to open close valves

OK so heres my 2 cents on the job: I noticed pits 200 does not have the stock piping that goes from the intercooler to the chargepipe, before you remove the fan there is a clip on the fan that supports that pipe, so that needs to be taken off to remove the fan. I got the evil box off fairly easy with some wd40 and my smallest screw driver shoved into the plastic guide then I wiggled that side out with the screw driver shoved in between the plastic guide. Then repeat on the other side. Other than that everything was smooth. I have 107k on my car and have been tuned for about 2k.

WOW! You were right, those are scary looking. Probably some of the worst before pics I have ever seen but I guess that is expected with over 100k on the car.

You notice any difference. It is usually with idle and higher rpm shifts were I noticed a significant smoothing after the valve cleaning.
