dowel pin oil leak maybe?
 

I just bought my first RX7 not too long ago and it had been sitting for a while. Started right up with cleaned terminals and a charged battery. Once I started driving around for the first week I noticed oil leaking. I changed the oil pan gasket and i still saw it leaking. Finally I pin pointed it to coming from where the "12a" was. After some research I'm guessing it a dowel pin leak but I was just wondering what exactly I would need to properly fix this, I know nothing about rotary motors. How long would this take and is it possible to do it in my garage myself?

Make sure it is just not the two o-rings under the oil filter pedestal. They often dry out and leak.

If it real is a dowel pin leak, the only way to fix it is to disassemble the engine and rebuild it.

Could I do that myself in my garage? How long would it take?

You mean rebuild the engine? You can do that in your garage as long as you have some basic mechanical talent and can follow instructions.

Ok yea sounds like I could do it then. What would I have to order? I saw pineapple racing had a water seal kit that came with a bunch of stuff including dowel pin o rings and it was only 185. Also is the omp block off plate the same for first gens as it is for 86-88 n/a. I was thinking about premixing.

Have you figured out if it is a dowel pin leak yet or just the oil filter?

Not yet. The previous owner put some kind of gasket maker along the edge by the 12a so I scraped that off. Starting it up tomorrow.
