1989 Mazda b2200 Oil Leak

I recently purchased an 89 B2200 SE5. It has a 5 spd manual transmission. After I got it home I noticed a pretty severe oil leak on the engine guard under the main pulley. I pulled the fan, pulleys, and timing chain cover off. There was no oil on the timing belt or noticeable oil at the bottom of the crank pulley. After cleaning everything up an driving it a few miles. There was oil agin on the engine guard in the same place. The truck runs very good and when I check the engine oil level it has not gone down. Any ideas?

Thanks
