Hi all - when I started my z4 ( 2.0) this morning I noticed a burning type smell and small amount of smoke coming from the engine bay - the area near the heat sheild - oily rather than plastic. The car had been sat over the weekend and I noticed it from cold almost as soon as I started her up. The smell/smoke lasted about 30seconds then stopped - i turned off the engine and started up again and no repeat. - checked oil and no issue nice and clear and electric gauge said level spot on, checked coolant and shows level fine- drove car to Mum and Dads about 45 mins each way and no repeat of issue - temp gauge fine and drove well without any problems no warning lights. No signs of any burnt wires/cables in engine bay- no sign of any leaks oil or otherwise- read a thread about oil leaks associated with the valve cover gasket but noticed the smell from cold so would not have thought that exhaust manifold would have been hot enough to burn anything off- just started her up again after being sat outside all afternoon and no issues- anyone got any ideas/experienced similar from cold? - I heard that the smog pump can also leak but cant see any signs of any oil etc . Could it be some crud from the road burning off?
Smoke from engine compartment - any ideas?

It sounds like you may need to replace the rocker cover gasket.. It can develop a leak at the rear and then drips occasionslly on to the manifold. Gasket is about £30 from ECP and it takes about 90 mins to do.. There are videos on you tube .
Alternatively and sspilt oil around the filler cap will travel under the cover to the back and have the same effect.. Have you topped up the oil recently and possibly spilt any ?

Cheers all - gonna get her booked into local indie as need rear pads and brake fluid also- hope its just the seal on the vacuum pump- been checking oil level and no change and no blue smoke from exhaust - also still has slight vacuum on the oil filler so hope the ccv is functioning ok -
Can you see if it's been replaced in the service history? Mine had done 97000 and hadn't been changed and the only symptoms were oil leaks and a rough idle. As soon as it was changed the idle smoothed out and the acceleration through the lower rev range was smoother as well. Only cost £120 for the part and an hours labor.
