so basically as the title says, i go out to warm up my car this morning, temp is 24 degrees, run back in get dressed, come back out 10mins later and smell burning oil. This is at least the 3rd time i have smelled this within the 2 years of ownership, but i can now say it is attributed to cold starts.

1. had the valve covers and valve cover gaskets replaced 2 months ago they are not leaking

2. i cant get into the spot to take a pic but the majority of the fluid is located on the undercarriage tray that sits under the transmission, right inside of the passenger side wheel, i have checked with a flashlight and simply cannot see where origin of the leak is coming from

3. i have googled the problem and found that mostly trucks and a few BMW's have had a similar problem, but their causes range from oil cooler to head gasket.

anyone with a Z experience this problem?

 

Always we gets less then 20 degree, no burning oil smell. I smell gas tho

 

do you leak anything during warm-up?

 

humm, water is dropping between exhaust pipe( where gaskets are) but it stops after it gets warm tho. But my car is in storage for winter, i turn the engine maybe once a week.

 

^^ok, well i just left a transmission shop they said its definitely oil, have an appointment with the stealership on monday has to be rear main or cam seal

 

ok got home removed the passenger side tire and started tracing, the leak is coming from whatever sensor/seal the green clip is directly attached to. It is located directly behind the valve cover in pics 3 and 4, anyone know the name of the part?

 

found it, camshaft position sensor
