I stopped at your cam2 deviations & the brown plastic you found in the oil. -9 is out of spec by a good amount. 6+/- is what is in the FSM. That much difference you should be throwing codes.

With these 2 items screaming at you, it isn't something you want to "get through the season"

I say all this at the same time I have a car with bad deviations that I think is the cam tensioner pads. It goes in the shop Monday to be looked at, verified and replaced.
Video/audio closer to the engine without commentary would help, but that ticking noise does sound like chain noise.
