BMW Repair: bmw fualt problem, bmw 320i, cylinder walls

Question
I got BMW 320i E36.it over flooding.after I put 5litre petrol it will just idle for few minutes then all the petrol will be finished.Then I will smell the engine oil and found that it is mixed with petrol.please advice me.

Answer
to go through 5 liters of petrol in a few minutes of idling has to mean it's going somewhere other than the running of the engine.  Look for a major leak somewhere.  The petrol smell in the engine oil could be the result a plug not firing and unburned petrol running down the cylinder walls.  But to have all the petrol go into the oil would mean your oil crankcase would overflow, and you would about have to have all the injectors shooting petrol straight into the crankcase.

I'd look closer for a leak.  Perhaps it is hitting the hot engine and evaporating.
