Hello everyone. This car has been too good to me this year and I feel like I’m due for bad news soon.

For a while I’ve noticed this smell in heavy traffic or when idling; when I pull away there’s a tiny puff of white smoke out the back of the exhaust and then it’s gone.

With winter season a few months away I thought I’d ask now in case I have a big job to save for!
Thanks

It could very well be trans fluid thru a faulty vacuum modulator valve on the gearbox or IF it is oil you may have worm valve stem seals. Does it puff out first start in the morn?

Pay attention to start up first thing in the morning. If you get a big puff, it would be valve stem seals , otherwise ATF as Robert indicated.
FYI, in my experience
Gray / Blue smoke is oil
White smoke is water
Black smoke is too much fuel

No smoke on startup, takes around 5-10 seconds - I imagine that’s just the usual white smoke you get from the water in the exhaust?
Had not considered the vacuum modulator value, I will do some reading up.
The smoke looks somewhat grey Thanks

Make sure indeed you do not have coolant in the oil or oil in coolant.
Hope you are not preparing a headgasket failure.

Maybe you should have your coolant test for gases in it
Here is an example

DOn't know where you leave, but exhaust condensation is usually not in summer, rather in winter, spring, when the engine warms and its not very hot outside. If you have just a little smoke that should be ok, but if its a consequant smoke, all the time when the engine is hot, thats very surprising in summer in your are in a hot area.

Thanks Jean, there wasn’t any smoke really when I had it running yesterday. I have now purchased the kit, arriving on Friday, I am praying it’s not my head gasket!
