('90 300SE)

In the morning, on the way to work, after the car has warmed up some...

Smells like burning oil in cabin.

Comes through the vents- either heat or cool air.

Only when I am at a stop light.

I repaced the VC as there was a little leak, but that did not fix the problem.

I have let the car warm up in the driveway but can not seem to find any smoke or locate the smell.

Anyone have any experience with this?

Thanks.
