Burning Oil Smell In Car Only

[Buptaboy]

Hi all,

Been having this problem a while now where I smell burning oil in the cockpit when crawling in traffic or car park manoeuvring. There is no smell from the engine bay or any sign of leaks. I have also noticed that if I turn the climate control off the smell goes. Any ideas what it could be??

I had a similar issue with a different make of car. Rocker cover had a slight leak which was dropping onto the exhaust and was burning off. No sign of leak from under the car.

But would that get into the cabin when all the windows are shut? It can only be coming in through the air blowers and there is no smell under the bonnet. No signs of the rocker gasket seal gone without taking the engine covers off.

It only smelled in the cabin on this thing and when sitting in traffic or parking up but not all the time

Hi I had the same problem on my 325 ci . It turned out to be the rocker cover gasket . Hope this helps
