you are correct. not as easily accessible as it seems, but it goes kind of quick still.

I think I have a bigger problem now. My wife and I had decided to take a little trip across state lines while the kids were at grandma's house. Around 300 miles in, I noticed that the 'add coolant' light began to flicker on and off. Then it finally stayed on. I checked my temp gauge and saw that the engine was starting to get a little hot. I pulled over and saw that coolant was steaming out of the coolant reservoir/overflow tank. I filled her back up with some water and drove to the nearest auto parts store.
I changed out the thermostat hoping that would be the problem. But the car began to overheat again. I then thought maybe it was the waterpump. Of course, it was Memorial Day and the quickest anyone could get me a waterpump was in 2 days. So I decided to try to make it back home.

Around every 20-50 miles, I would have to pull over and refill the water. No big deal. But then my 'oil level low' light came on. So now everytime the engine started to overheat, I would have to fill it up with water AND oil.
Now the car was really smoking as I drove it down the road.

Well, we made it home and now I'm trying to figure out what's wrong. Sounds like it's a headgasket to me. But I don't know how to translate that into rotary motor terms. How hard is that gonna be and what's it gonna set me back? Or, is that really what the problem is? Could it be something else?

since the rotary has no heads, the gasket that you are speaking of is between one of the irons and one of the housings. the bad thing about a rotary is that you need to rebuild the motor when it comes to this.

a rotary rebuild is usually expensive and extensive. you need a full gasket set, new or machined housings (odds are new), possibly an intermediate iron, and some apex and side seals. if you are mechanically inclined, i would recommend getting some info on rebuilding your own motor, getting new housings, and sending off the rotors to get new seals pressed in.

if you are not mechanically inclined, i would recommend getting a motor already built from someone local and having someone drop it in for you. otherwise, you are looking at a few grand to have it rebuilt.
