It would be very difficult to find any sort of adapter to hook a gauge up there.

Plus, you're not really interested in the oil pan temp, you're interested in of the temperature of the oil in the engine!

 

OK. so talking about this. I got a picture just so people can see the sensor he is talking about.

I also. Happen to have a Auto Meter mechanical oil temp.
This gauge come with a 3/8 NPT and 1/2 NPT.

SO i tried the 3/8 and it goes right in there.
Here are the pics to proove it.


Again. Im not sure if this would be the best place for the oil temp.




http://www.rx7city.com/Manuals/88%20...UBRICATION.pdf Page 3 indicates that the oil pan isnt too bad of a spot..

for example it proofs that the RB oil filter adapters are not as good because it would get cooled oil from the oil cooler. Right?

 

no?
