Oil Leak
In addition to the 85 GSL-SE I just bought I also own a 85 base model with a 12A in it. Can anyone tell me what the part is called that the the oil filter screws into? Is it the oil flange or something. I know this is a stupid question. What ever it's called I can see oil leaking from the bottom of it. Is there a gasket or something that I can buy to repair this part? The car has 147000 miles on it but runs fairly good and I don't want to have the motor ruined because of some stupid leak. Please help. I'm new to this forum but have found alot of awesome information and I really appreiate the feedback. One more thing...where can I get an electric fan to replace the stock one on my 85 13B? or is that even a good idea?...

You mean the oil cooler?
You can try to replace the O rings that are a possible cause of your leak. That or even the whole banjo pipe replaced.
You can get plenty of e fans out there.. check out any local rotary place or do a search here, it's been covered a lot. Tons of people get a e-fan from an old car and do a convert

Its not the oil cooler, the SE's had a front mount style.
But, it is the 2 O-rings under the oil filter pedestal, and its very straight forward to do as Dan said.

I guess he's talking about the Beehive cooler....You'll need four o-rings for the bottom of it....not sure of the size, but their part number would be 9954-10-1601 Lot5E10 from Mazda

12A oil cooler leak
Replacing the o-rings is straightforward but not quick and easy. The banjo bolt
is 23mm, I went to Sears and bought a wrench for it. only way I could get the job done was to be going under the car and back out several times. the old o-rings will bbe crusted on there. Two o-rings go between the cooler and housing flange, and another two go between the "sandwich" layers of the cooler. You can get the right o-rings and crush washers from Mazdatrix, or from Lowe Performance in Sarasota Fla.

Here is a thread from the 1st gen archive about this very subject, and it even has a few pics.
BTW, there are 2 nuts under the cooler, and 1 bolt under the "Rats nest" holding the cooler to the motor, along with the large banjo bolt previously mentioned.
A total of 4 o-rings are needed, 2 between the cooler and motor, and 2 between the cooler base and the cooler itself. Just don't forget the crush washers for the banjo bolt, or it will likely leak from there after reinstallation.
