There are several things than can make the puddle, the gasket on the valve cover slipped when you put the valve cover back on? The gasket did not seal because the bale has lost it's tension. Finally it could be the valve cover gasket surface is not flat and even so a very small part did not seal. I made an article on the site here on adding tabs so the gasket can not slip on the install. I also made a steel form that was in the shape of the gasket that I would use to check for valve cover flatness and could flatten the edge if needed. The weak bale can be fixed by bending it so it presses on the valve cover tighter.

If the car is not sitting level then an over fill of oil can easily cause a leak out the push rod tube or valve cover gasket.
