I see half of my valve cover bolts are rusted. I only have 50K miles on my 2013 Cruze LT.
Also, I see a lot of rust build up on those bolts that hold the engine shield I think.
This looks like excessive rust for a 4 years old and 50K miles car. Should I worry? Is this normal? I need to keep this car for 60K more miles and 6 years.
