My car starts up fine. I do notice when warming up the car, there's grey smoke. After normal warming of the car, no more grey smoke. I drive it and no smoke out the tailpipe. Is this normal for rotary motors? Any info would help.

 

sounds like oil control rings. will need a rebuild to get rid of. i am in the process of rebuilding an engine that had the same symptoms but it would be a good idea to rebuild the engine before it blows cause the inside of the engine will be all nice and shiny and will make for a nice rebuild
