Any ideas why my car smokes sometimes it only does it when its ticking over never when driving and it seems to only do it if im at traffic lights for instance.now the car runs perfect boosts fine doesnt use oil or water and its deffo not the head gasket i can guarantee that.

The smoke is a light greyish colour

Im no mechanic but im wondering if its over fuelling on tick over?

greyish /blue is normally oil,

 

smoking from exhaust or under bonnet? Under bonnet area could be rocker cover gasket gone and leaking onto exhaust 

From the exhaust mate its wierd cos theres loads but only now and then would it be stem seals then although it doesnt use no oil at all really

If it's shortly after start up and you've got a big bore zorst it could just be moisture .

Just keep a close eye on your oil n water levels

Classic signs of a worn turbo usually

i think

maybe

hmmmm

I think ive solved it.it only started when i had various bits changed on my exhaust and im hoping its just where ive lathered it in exhaust paste.

Well fingers crossed anyway because thats when it started...

Cheers for replys tho lads much appreciated

Well why didn't you say that in the first place..... 😜
