Oil Pump problem? on 2000 Chevrolet Blazer

What would cause oil to be sprayed all over the front part of my engine?

fornt oil seal leaking and it sparys the oil all over when it is running. get it looked at as you could be risking a fire.

How hard is a new seal to replace? What is it attached to the oil pump? Sorry if I sound stupid, I can't work on the new engines: I miss my 4 barrel carb and no wires. Now that I can work on.
