Hello everyone, A few months ago my 2010 RX8 started expelling blue smoke from the exhaust (it always had good compression), I followed the workshop manual step by step (a friend even lent me both OMPs to see if that was the problem) I finally concluded that one of The oil control rings of the first rotor have a problem, possibly due to wear, the engine has about 150,000 km and the oil control rings were not changed in the rebuild that was done 25,000 km ago (3 years). Finally I bought another engine with good compression and installed it in my car and so far so good. Now it was time to open up my old engine for repair. I wonder: What does a bad control ring look like? Should I find some wear in a certain place on the ring, or could it just be out of place? Aside from the rings, how can I know which other piece has wear so I can buy it as well? I did not find information on the forum related to how to know which seals you should buy and which ones you can maintain (considering that the rebuild of my engine was only done 25,000 years ago and since then I have taken great care of it. Wish now, very grateful for your recommendations.

 

You should replace all seals. Reusing seals is asking for trouble. You wouldn't reuse piston rings, right?

 

Hello Loki, thank you very much for your response.
1. Which kit would you recommend I buy if the damage was only to the oil control rings?
(Considering that it had good compression)
I am searching here: https://www.atkinsrotary.com/Rotary-...-rebuild-kits/
2. Do you know if there is any material that helps me identify parts in poor condition? (it's the first engine I open)

 

be careful with Atkins, they’re know for selling non-OEM copy cat parts that appear to be in OEM packaging …
.

 

Anyone correct me if I am wrong;

The wear value is specified in the service manual for the FD; wear mark on the oil seal cannot exceed a width of .5mm.

See page C56.
