I thought the filter was a spin on cartridge, but with this design I'm not sure it will change anything. "Chevron" design is Purflux patented and used on most of their oil filters...they are said to be good quality, and I use them or MANN (made in Germany only). I now stay away from Mahle...they rusted in my drawer
Can you remove the vave cover and push gently on the lifters with a screwdriver or something? If they are mushy...maybe you can put them out and clean them.
Think it is the same:

I think I may be able to remove the covers to inspect the tappets but doubt very much you can tell if they are not working properly. I may be able to see if any lobes are damaged though or even if the flat srufaces of each tappet look damaged. I believe it has a gasket whereas the lower half uses gasket sealant, the black stuff.
