Would like to know the miles when pics were taken (?) Any idea?

According to the post on page 14 those photos are from a 2014 Corvette LT1 with 5500 miles.
I am on the fence with this one. I added a catch can on my gen 5 when I did a cam with bolt-on build. I would catch 1-2 oz of stuff every 1000 miles. But when I had a cam failure after 17K miles (that's a story for another day) and had to pull the heads for a re-build - the piston tops and valves did not look all that clean. In fact some people asked me if I ran cheap or crappy gas and the answer was no. I only use top tier 93 octane. So, I can not with any confidence say a catch can made any difference. I am leaving my LT1 alone. If I keep it long enough that it may need a valve cleaning - then so be it. I'll deal with it then.
