I was looking at a 2009 Turbo cobalt the other day, the owner told me that it was leaking a little of oil trough the valve cover, while I was checking out the car it didn’t seem like a terrible of a leak, is it normal?

 

It's 10 yrs old and it wouldn't surprise me if any car of that age didn't have a valve cover leak.

 

Valve cover its not hard on these cars. Better than a rear main seal leaking
