My 180sx has been parked up for about the last 5-7 months, and hadnt been started in 3 months until last week, started fine.

But when i left it running, it was blowing alot of white smoke, now at first i thought condensation or water in the exhaust, then the cold weather, but it continued on, even when revving up when it got a little bit worse.

Now i had this problem the same before which turned out to be no water feed to the turbo and the turbo was knackered, the new turbo i have is in the car over a year but has only done about 7000kms-10000kms. So not sure if it would be that.
The car was fully serviced about a week before the car was parked up also.

The smoke has no blue in it so i know there is no oil, so is it something like turbo or gaskets or something to that effect, or is it just the effect of being parked up for so long???

Any help appreciated

Cheers
