I got the same issue when I start my car sometimes a huge cloud of white smoke pours out, but when I shut it off and turn it back on it's fine. Also when I first start me car and drive away Blue smoke pours outta my exhaust, but when it warms up it stops why is that?

The solutions have already been posted:

If burning oil, either replace the oil control rings or start running the Lucas in the oil.

If burning coolant, try the Alumaseal as detailed in the link I posted above.

Ten minutes of reading may save you the trouble of pulling and rebuilding the motor...

I kinda have the same problem. I just noticed it today. Doesnt seem to happen, except on first start of the day. I was just thinking it could be water build up in the engine, exhaust, etc since it was raining the night before. The smoke goes away after warm up, and doesnt come back during drives. Do I have anything to worry about?

ps its decently thick white smoke.

white smoke coming out when its cold is normal....just the condensation from the exhaust...if ur getting blue smoke until its warmed up as u claimed...ur not allowing time for the rotary to warm up..if u drive without warming up the motor..you will get alot of blue smoke and thats bad for your motor

from the little bit of stuff i know about rotaries it sounds like you have bad seals which is allowing coolant to leak into the combustion chamber and then it burns out the exhaust as white smoke. i had a similiar problem with thick white smoke pouring out the exhaust along with the engine overheating which pretty much meant my seals were bad and i needed a rebuild. i tried the block sealant Kentetsu is talking about and the smoking/overheating problem stopped. this isn't the best thing to do because the sealant can start to clog up the radiator and other parts. its up to you if you want to try it, it worked for me but the best thing to do is get a rebuild or new engine.
