What's the 2014 Chevy Cruze valve cover bolt size?

In order to take the valve cover off on a 2014 Chevy Cruze You will need a special E10 socket. The bolts have M6x30 threads with an E10 external torx head. Take care when tightening them is it appears these bolts can be brittle. There's been numerous complaints of the bolts breaking off the cylinder head and would require some specialized extraction tools to remove. Then the oh whole would need to be re-tapped with a larger size. You could also drill out the hole and install Helix coil which would allow You to use the same size bolt. Although I would not do that myself I would have or machinist do it for me.
