why does the first pic look like a twig is on the left valve and a leaf on the right valve
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?

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.
