I've only owned my FC for 3 weeks and I cold started it after the car was sitting in the driveway for 3 days. There was white smoke from the exhaust

87 turbo II
compression 100

Had it checked out recently at reputable rotary shop and they claimed everything was okay.

As I understand white smoke is burning coolant. Other than apex seals, where else could coolant be leaking into engine? Why is that the white smoke is only there when it sits?

Sorry for all the ignorant questions. Thank you in advance.

 

well if its cold where your at it could be that.it could also be burning oil.i would get the apex seals checked

 

Apex seals don't leak coolant. Coolant seals will though.
That said, if your shop checked it all out (including pressure testing the cooling system), it may just be cool ambient temps. That will cause water to condense in the exhaust system during cool down, which is turned to steam at the next start-up.
Burning coolant has a distinctive slightly sweet smell, unlike steam.

 

Well If the apex seals where Broke it would smoke as well it could be a broke rotor housing but you'd lose compression.im not 100% sure

 

^ wat

this just happened to me. upon engine disassembly it turns out the coolant jacket gasket was cracked, not the iron, the actual rubber gasket. requires a rebuild

 

Is it running rough on cold start? Smell the exhaust.

 

Have you noticed any loss of power?
if it is ligh smoke for less than 5 minutes, could be condensation.
if it is heavy smoke and last longer than 5 minutes.. coolant..
check the oil and coolant prior and fter a good drive, (let it coold down)if you notice
no change. it might be just condensation.
let us know

 

pretty normal - wouldnt worry to much about it

 

listen to your shop and worry about it if you notice any other symptoms like rough starting, overheating and overpressurized cooling system.

If youve completely blown a coolant seal you'll know it, the car will start rough and sputter, coolant level will drop fast, and you'll be seeing a lot of thick white smoke ; so much you won't be able to see behind your car and the car will overheat fast.

Its likely condensation that is coming out (water in the exhaust).

Even if it was a coolant seal slowly going it will be drivable for a while if you keep an eye on you coolant level and try to top it off as often as it lowers.

Just drive it have fun with it, until you really have a problem, just stay on top of the coolant staying full.
