Today I changed the valve cover gasket and chain tensioner gasket...I found the camshaft a bit wear.What do you think?my car is 11 years old and 90.000miles on the tacho(but not sure,I own it for 4 years)

This worries me most

and this

Other cam lobs look normal I think

Looks fine to me mate. They are just different colours in the metal were it has been running but no sign of blueing, doesnt look like any scoring at all and lobes look fine which are the place that you would see wear.

The bit that worries you most is from when it was made the machining hasnt gone right upto the end as it doesnt need to.
