compresion test, also do a vacume test see if shes leaking anywhere. and the oil on top is most likley from spilling when pouring which shows a careless owner. be warned!!!! and every other standard test, best to get a mechanical inspection by a shop or somthing.

it might be a valve cover gasket leak... they are very easy to replace, and cost less than $50. I would reccomend getting a compression and vacuum test done to make sure the engine is in good health

just take it to a BMW shop and ask for a used car inspection, usually they charge half an hour labor, if the owner wont let you then you dont want the car. The vacuum and compression should be fine if it runs good and doesnt have any loss of power
