Thats I think quite a normal wear pattern for a 60k s54

What you also can do is check the oil pump pressure valve piston. They can have some wear too:



In europe its common practice (in germany at least) to replace those too because they're fairly cheap and the procedure is very simple if the oil pump is already dismanteled, there are even versions which have a special coating.
However I dont know to what extend this wear has an influence on oil pressure or future wear, but the parts are damaged to some extend.
