Hello all:
I just bullet proofed my 2006 F250 6.0L crew cab truck. Engine runs fine but I noticed a diesel fume smell when I have the interior fan on at low or idle speed. There is no smell when I am going down the highway. I have looked for a leak. I have listened for a leak. I can not fine the leak. Is there a way to visually see a exhaust leak. I believe it is an exhaust leak because of the diesel smell.
Thank you in advance.
