Fumes entering cab (sometimes)

ktmmike · 01-11-2015, 02:43 PM

2014 Sport Package 370Z Coupe

Sometimes after driving for a while with the heater on, I can smell some sort of fumes in the cab.
NOT exhaust fumes.
Smells more like oil breather fumes possibly??? Not completely sure.

Intermittent. Some days I can smell it on a short drive (or not).
Other days I can take a long trip and not smell it AT ALL.

Never smelled it in the summertime with or without A/C.
Seems to happen only when heater is on (and even then, only sometimes).

When I smell it in the cab, I can stop, lift the hood, and smell NOTHING anywhere under the hood.

No exhaust leaks.
Checked entire engine for any kind of oil seepage onto hot engine surfaces.
None. Perfectly clean.

QUESTIONS:
1. Has anyone experienced this?
2. Is there an existing thread on this problem?

Thanx for any help,
Mike
