1935 Ford Oil leak in front

[RandyLPeterson]

I have a friend with a 35 ford Tudor.. It is leaking oil Front Passengerside when it is running.. Is that a breather in the front corner of the oil pan.. Theres a slot there and it drips oil out when it is running.. I have not worked on the older Flatheads so this is a new one.. I was thinking he may have put too much oil in but thought I would check with you Experts THANKS
