In reply to blackcat:
Strange set of symptoms... so all happened at the same time?
Is the engine transverse (crank orientated side to side) or longitudinal (crank along the length of the car)? If it is the latter and you experienced any clutch slip, then it could be a galley plug leaking into the bell housing and the oil burning off the clutch. The clutch slip would likely be very noticable though.
If the engine is transverse then your exhuast manifolds will be at the back probably (can you see them?) and oil could be burning off these.
