Need help on this.

Im planning to purchase an FD , but only issue with that is one of the rotors is running low on compression. Now I dont really know much about these engines, but is this a big issue? Or can it be done my a local mechanic?

I could be a lot more helpful if you posted the compression numbers. If any of the rotors have 0 compression on any faces the motor is blown and must be rebuilt. This is not something I would consider asking a mechanic with no rotary experience to do. You should see 3 even bounces on each rotor of 95 psi or more (120 would be a perfect condition engine). Anything less than 90 on any of the faces and I would start planing for a rebuild in the near future.

You do not want your engine rebuilt by someone who doesn't have experience with it. While many DIY'ers have rebuilt engines using videos and manuals with success, many have not been successful. If you're going to pay a professional mechanic to do it, you might as well pay a little more and get it done by someone who can guarantee the work and do it properly.

Keep in mind that while you only have one rotor with low compression, it's going to be a full engine rebuild. The whole thing comes apart to do the work, and if you want it to last you build everything well when it goes back together. This is no headgasket job.

Depending on how low the compression is you might not need to rebuild it right away. But I would never buy such a car assuming that is the case. Assume the worst and spend the extra money on additional preventive maintenance items. Keeping an FD in good shape is like that.
