Need some opinions on where to go from here...

It could have flattened a cam, then it sat without running for a year. With all the metal in the oil and now the rings are sticky.
About 15 mins into the initial cam break in I shut the engine down as I had tried a 1 piece pan gasket, and it did NOT seal...So at that point, I drained the oil, dropped the pan, new pan gasket, then back to break in for another 20 mins. I kinda figured that if I flattened a lobe, the oil at that time would have shown it, but it was clean....I guess I can drain the oil now and have a look, although pulling the intake manifold will also tell the story.

Also, there was only 1 cylinder that was sticky, so I am just hoping that maybe its carbon considering how rich it was running
