Hi all

does anyone know what this white smoke coming from the engine bay may be? Or is it bad? Seems to be most noticeable on cold start up.

Here's a video of it. Very faint smoke

thanks in advance

 

Does it smell sweet, then its coolant.
Does it smell like burning oil? You might have a leak around the turbo
Does it smell like exhaust? You might have an exhaust leak near the manifold/turbo/downpipe

 

doesn't really have a smell. I think you're right on it maybe an exhaust leak

 

Sounds a lot like an exhaust leak in the video. That flapping paper sound.....

 

Another option is to get a fluid transfer pump ($8 at harbor freight I think) and some cheap gas station cigars. You plug up your exhaust with the output hose and put a lit cigar into the pump intake hose. It may take a few pumps to get it filled up, but the nice heavy smoke from the cigar will be readily apparent without you having to make a bunch of noise out heat things up.

The best part is that it’s cheap! I did this to find a vacuum leak and it took 5 minutes.

Another video I saw was to use the outlet of a shop vac plugged into your exhaust and then spraying every exhaust joint with soapy water to find the leak
