Hello I have a 1985 Mazda RX7 12a with a beehive oil cooler. I bought this car as a project car and have finally started it only to find it was spraying oil everywhere out of the engine hole. I believe this threaded hole goes to the beehive oil cooler through a hard line. I tried looking over the internet for replacements but could not find anything. Does someone make a oem one or is there an aftermarket one I should look into? Any help is much appreciated.

looks like Atkins has them. Or you can try a Mazda dealer.

 

These oil cooler lines will rust and leak from time to time. Mazda has thankfully kept them in stock. As stated above, Atkins Rotary or Mazdatrix should have them in stock or you can use the provided part number and order the line from your local Mazda dealer. Do not forget to order the four corresponding crush washers for the banjo bolts as well.

 

its NLA in the US, but looks to be available in Japan, https://www.amayama.com/en/part/mazda/n23114720b

 

Thank you so much everyone I appreciate it.
