I have 2001 bug wrx that has started with an oil smell inside when your at the lights. Got home tonight looked under the hood and I see smoke from behind where the turbo is situated. Can't see any oil and doesn't seem to have lost any either. Not had chance to have a proper look in daylight as yet but any help is much appreciated

 

Could be a breather pipe that is leaking e.i. crank breather hose, can get quite stinky if thats not connected properly, seen that happen a few times, but be sure to keep an eye out for oil leaks.

 

mine had a slight weep from a the rocker cover gasket and was dripping on my headers

 

I would say rocker cover.

 

Gonna give it a good check over in the morning. I think there is a few things it could be like oil line to turbo leaking onto down pipe or rocker cover gaskets. Even a split cv boot spitting grease onto hot parts. Hopefully find the problem in the morning.

 

I had this in my old classic was rocker gasket causing oil to drip onto exhaust!!!

And again Rocker Cover Gasket......comon failure but easy fix DIY job

 

Well it looks like the on the rocker gasket one of the fixing bolts has a slight weep causing the smoke! It's the only place where I can see any oil. Should be an easy fix!

 

I had this. Was a split cv boot.
