Oil leak from Engine valve cover

I was regularly noticing the oil spill out of the valve gasket cover and was told by the mechanic that I need a new gasket. I have removed the valve cover and noticed that the gasket is in a good shape and didn't need any replacement. I have cleaned the gasket, reassembled the valve cover and applied little extra torque on the bolts. No more leaks.

If you have a similar leak situation on your car and would like to repair it and need some help, then mail me and I would share additional information along with pictures.
