Crankshaft Seal?

[blackbird]

I think I originally posted this in the wrong area.... Hope this is the correct area LOL

Based on reading through several post I believe I need to replace the front crankshaft seal. I have a couple questions before I dive into this problem..

What are some of the indications that this needs to be replaced?

And honestly how difficult is this project.

This is what is going on, I have an oil leak at the front end of the motor dead center. It appears to be coming from under the front timing cover at the oil pan. I have replaced the oil pan, so that can't be the problem.

I have an 87 Samurai.

Thanks in advance.
