So no cleaning at all up to 130k? If so, I'd say that's pretty remarkable for any DI motor.

Wow, big improvement! Were there any obvious symptoms/issues or was it just a good time to do it? Did you notice an improvement afterwards?

Yeah zero cleaning or cleaning additives up to this point. Just regular oil changes and and a lot of highway miles.

If I'm looking at it right that cylinder 4 looks rough.
Great job
Great job
No symptoms at all, I’ve just seen the aftermath of DI and new it was in my best interest to clean the intake valves out sooner rather than later. Also prepping for turbo upgrade so it was on the todo list.
Huge improvements...it honestly feels like a different car. Throttle Response is instant, and turbo seems to spool faster.

Lmao NE winters are rough man. There’s layers of debris in my engine bay. I’m guessing some got dislodged when I took of the manifold.

130k was the sooner option? Lol
also nice to see how much better the gen3s are with carbon build up...my mk6 gli looked like that at 114k and it had already had 2 physical cleanings before at 50k and 80k . Before n after blasting

Was this a media blast clean or soak and scrub method? Are there any issues with using the soak and clean method, for instance if the some of valve cleaning solution gets past the valves. Could that be a problem? I only ask because I thought I read somewhere that it could happen and maybe has some adverse effects.
This was cleaned using a combination of scraping with pick tools and also using a walnut media blaster. Which is what I’d recommend for anyone looking to clean their intake valves.
I also read somewhere on this forum advising against using chemicals to clean the intake valves. I think they cited the possibility of it leaking into the cylinders.
