Smoke, fumes, MPG after swirl replacement
 
I had my swirl motor replaced on my '07 WK under warranty just over a week ago, and since I've had it back I have:
  1. strong diesel fumes under the hood and also entering the cabin
  2. smoke coming from under the hood when engine is hot, vehicle is stopped and idling
  3. my MPG has decreased by around 3

First I was thinking that the exhaust intake of the turbo wasn't re-assembled properly and not sealed but that I can't feel/see exhaust coming out of those joints.
Now I'm wondering whether a fuel rail is not connected tight and leaking. Anyone have any suggestions or experiences to share? I'm taking it back to the dealer tomorrow, but as others have noted, my dealer too can barely spell diesel.

I have heard that the intake manifold sometimes gets cracked when re-assembling after a SM replacement. What did the dealer tell you when you took it back in?

It turned out the exhaust flange to the turbo-charger was not aligned properly. In my case, that's just a tech doing a sloppy job, because they rush through this since they get paid per job. Don't even get me started on that.

Exhaust was blowing in and by the turbo-charger, which sits up close to the firewall where the cabin air-intake is and that's why. It's a simple fix and not needed if the job was done right to begin with.
