Is this wear on the rod and crank bearings normal?

[andyp]

Given that I have a 2.0CDTI engine (A20DTH) and that last winter I had the low oil pressure light pop up for a second or so when starting the engine in the morning, I thought I should replace the O ring on the oil pickup from the sump. 

After taking the sump off and removing the O ring I did notice that it was stiff and brittle and I replaced it. Since the O ring was so brittle I decided to take a couple of bearings off and inspect them and the crank. I've uploaded some images.

Can someone please take a look at the images and based on the damage advise what I should do? Thanks!

Hi
Run your finger nail across the crank bearing surface if you can not feel any steps its ok replace bearings with new stamped on the non mating surface ie the side not in contact with the crank will be the size marked std or +10 etc remember to coat new bearings with assembly lube when fitting be very clean and torque up bearing caps to correct setting
also fit new sump gaskets etc
hope this helps
