Poor guy but he didn't do quite enough research. In 2013, Mercedes made a switch in the GLK350 to a very modern DI engine with start/stop and it's a completely new design that was actually designed in conjunction with Chrysler. Anyway, it's a 3.5 V6 that is smooth as silk and makes about 300hp.
The filter is an unusual design that I've never seen before with some prongs on one side. Both engines use a canister filter so the oil change place where he took his parts to didn't really know what they were doing. Anyway, sounds like he did some internal damage to the engine although it still sorta works.

I will say, it's kind of crazy that the oil filter system was designed in a way that it's possible to starve the engine of oil and that we're relying on some small plastic prongs to avoid lower engine damage.... so that's not great.
