My 86 RX7 smokes really bad over 5000 rpm. I have had the car for about 10 years and have 225,000 miles on it. I still drive it about 40 miles a day to work. Its been doing this for 2 years now, I nurse it and it just keeps going. It also smokes when you first start it, worse if it has not been started for a couple days. It started doing it after a thermostat failure and the engine got a little hot, it wasn't over the red on the gauge, but it was towards the top before I got it replaced. I researched my problem on the net and I think my inner oil control ring is bad. Does this sound right? How hard is it to replace it? Let me know what you think? Could it be something else?
