Oil leaks from under filter I'm guessing it's called the oil filter housing not sure if there is a gasket or something

 

Oil filter pedestal o-ring leaking. Should be able to order a replacement from your favorite parts source for ~$10 I believe.

 

The oil filter pedestal's o-ring's have likely dried up and are hard and brittle. This will cause oil to seep form between the rear iron and the pedestal. The o-rings are easily replaced after removing the pedestal and can be had from Mazda pretty quickly.

 

Could I order the o rings online or I have to go to mazda
