oil leak/couple of other things.

[droneboy]

hey guys

New member here and also new to the bmw world! i picked up a 2003 318 ti se last week and went to work today in the rain!! when i reversed i noticed a spot of oil on the floor, then a touch more when i looked under it.

I've read VGC online is the most common cause of minor leaks. i'll put up some pictures below.

The other parts are:
1- when the car starts it makes an odd noise like maybe the starter keeps going when the engine fires for about 2 seconds. ill have to record it tomorrow when its a cold start.

2- once warm the car idles at roughly 600-700 rpm but sometimes dips low and the engine chug side to side slightly, maybe vacuum leak?
i've yet to take covers off to inspect the hose's though.

3- possible related to a vacuum leak but from roughly 2.5k under hard load the engine hesitates just slightly.

4- should it be tough to put the dipstick back in? i really struggled as there seem to be a cross plastic bit on the dipstick.

5- does this model come with a cone filter in an air box as standard?

cheers
