Noticed a small oil spot under the car and after pulling the pan i traced it to the oil cooler under the filter housing....got the gasket from ford and changed it ...No leak for the first few drives ..then today after car and coffee i looked and sure enough the leak is back .....the leak must have started on the drive home as i looked after i park at cc and it was dry........ the old gasket looked okay when i pulled it.... see pics...... any thoughts on a fix?
