Do not tighten the breather covers to the same torque as the valve covers. They are different size screws so different values apply. OEM breather screws are aluminum so they are or were tightened using much less torque than steel screws and used only once ideally.
The torque value of the breather screws is around here somewhere.

After I tightened the 2 bolts that pass thru the breather cover, I checked the remaining valve cover bolts. Found all of them less than 10 N-m. Re-tightened these bolts also. Then I tightened the 2 small hex head machine screws in the breather cover to 5-6 N-m (slightly over snug).
Found this info from one of my posts on fixing the breather cover leaks.
