Oil Leak
 

I recently purchased a '86 n/a with 96k. I have been soaking up the great advice offered on this forum. I already completed several preventative maintenance projects and the car is running great, except for the oil leak that developed at the rear of the engine from the banjo fitting on the oil cooler line. Anyone spring a leak at this spot. I have had a lesser leak from the front of the car. I have not removed the huge plastic piece attached to the bottom of the car to investigate. Most likely, the other end of the oil line is leaking at the cooler too. Can the washers just be replace on the oil cooler line or is it recommended to replace the entire line? Should the lines be replaced as a set? Is mazdatrix the best place to get the lines? I looked at Corksport and the pair sells for $119.00. Any advice would be appreciated.
