Looks like my valves at 30k now, no catch can or manual cleaning. All I've done is pennzoil ultra platinum oil, kept the pcv valve clean, and everything is stock. I think next spring I'll try crc Gdi cleaner and take pictures again with the borescope.

The catch can is spliced into the line that goes directly into your intake manifold. The oil that ends up in the can was on a direct path into the intake system. No doubt about it. Does the can catch everything? No. But he would have had those 6-8oz's circulating through the manifold if he didn't have the can. When I first saw this thread, I was thinking that it was the Penzoil that was crap. And really, your pics don't do much to change my impression of that.
