It does work it's just garbage lol. Grab yourself an oil catch can or bump up the rpms.(2thumbs)
Chris so can i pop into fake manual and let the rpms go up higher than normal auto allows? And what does high mean 4000 up?

This is a petrol engine right?
Why did you take it apart?
What fuel and oil are you using?
Here's an old post on 1/11/2017 by Chris_Top_Her showing how much the blown-by gasses with unburned fuel、engine oil、and sludge collected in his catch can after only 5,000 miles. Unfortunately the picture is no longer available, and if I remember it correctly, it had about quarts/500 cc in the catch can!intake manifold of a 25000+ km 2016 mazda cx-5

any thoughts on how to effectively remove those gunk on intake valves?

I would suggest to manually clean those valves since you have the manifold off. That carbon looks bad .
BMW owners with direct injection engines have been walnut blasting their valves for a few years now to clean off the deposits. I was hoping Mazda solved that issue. May not after seeing these pictures.
One anecdotal example of carbon build up does not represent a systemic problem throughout the Skyactiv lineup. This is the only example of buildup I've seen, if this was a widespread problem I'm inclined to believe we would have seen more incidents over the years.
