Everytime i start the engine cold it smokes for about a minute it does'nt worry me but i was courius as to why the engine did that ? the engine has about 60,000 mls
and has no upgrades 12A stock

drewroman

is it white smoke, blue smoke, does it smell like burning oil or sweet like coolant? is it like ALOT of smoke (enough to be embarrassing) or just a little?

a little blue oil smoke is probably okay, I don't think any of the RX-7s I've had didn't smoke a little on a cold startup... quite a bit of any kind though is abnormal and probably a bad thing

You'll especially get a big puff if you chocke the car during ignition. Unless it's absolutely necessary, I prefer not to use the choke because my neighbors give me the evil eye. Remember, 7's burn oil with their fuel so I always assume it's that residue getting blown out that drips down into the intake after shutoff.

yeh, when I start up my car in the morning it sometimes blows a big puff of blue smoke, but after a few seconds I wont see it for the rest of the day.
