New guy here..Just bought an 08 3500 6.0 box truck with 73k miles and have a few things I need to take care of before I start driving it too far. Due to low oil pressure 12/25 psi idle/highway and having a P0521 code, I'm parking it until I can tackle these three things

 

-  Replace O-Ring on oil pump pickup tube

-  Replace or clean oil pressure sensor filter (should be easy since I can access back of motor from inside truck)

-  New Synthetic Oil + larger filter

 

Other than that, is there any kind of preventative maintenance unique to these motors I should be aware of?
