I will echo what the others have been asking: "what has changed"?

It sounds like only the oil. It could be coincidental, but that's where I would be looking. The filter is OEM, but is it possible that the part number was incorrect? Did two rubber o-rings come out with the old filter and did new two ones go on the replacement filter? Is the oil level correct and does it match the amount of oil you put into the engine? The little peg at the bottom of the filter (as Newegg mentioned) is relatively unique to this engine

I agree on the rod knock. It's higher pitched, like a collapsed lifter or an injector. I'm not sure of the oil capacity of a 2010, but I thought it was closer to 9.0L.

It is probably not too difficult to put a temporary oil pressure gauge on the engine somewhere if you want to verify that end of things.
