oil leak in front of drive shaft

[85bronco2]

i have a bad oil leak in front of my engine looks like its coming out of the space the drive shaft connects to the round thing that turns the belts(sry for not knowing what this stuff is called im kinda new at this)how can i fix it?

The thing that turns the belts is the crankshaft pully which is connected to the charmonic balancer (thick black round metal thing) which is connected to the crankshaft. The thing that would most likely cause the leak in the front of the motor like this would be the oil pan gasket. it could be gone, worn or the bolts are missing or stripped out. check fo these things first. GOOD LUCK!
