Hey, I started my car today and while it was idling I noticed like a strong exhaust smell I looked to the rear of my car and it was blowing white smoke?
The car hasn't been driven for almost 3 months (due to me losing my licence.) So I dout it could be a gasket or turbo leak.
My battery ran completely flat the other day aswell, could this of temporarily screwed my tune.
I am really confused the last time I run my car it was fine, please help.

 

the battery dying should not affect the tune. did you turn the car off immediately or did you let it idle some more? have you tried to start it again and does it still have the white smoke? check the radiator to see if its milky. might have blown gasket.

 

Yeh I stoped car and and checked my radiator but couldn't see anything looks fine?
I started the car again and no smoke til it heats up or revved. I can't see how I could of blown .he gasket it hadn't been driven hard in ages. Is there another way to check?

 

Do a compression test. Should tell u everything just to be safe.

 

Cheers for the info guys. I'll do a compression test tomorow. better not be blown tho ive only had the car for 3ish months and haven't even driven it hard yet. So pissed

 

could just be burning all the old build up in the car for sitting for so long

 

could have just been condensation in your exhaust from sitting.

 

Is it thin and light or thick and heavy smoke?

 

Does the smoke smell sweet?
