    I'm no mechanic but could it be something as simple as the 'o'ring on the oil filter housing cap ?
    Oil,like water has a habit of showing it's self away from the source of the leak ?

    If it's the filter cap O ring then you should be able to see it leaking quite easily by wiping around and running engine.
    I would suggest it is more likely to be the the filter housing to block joint (which becomes brittle with age) is more difficult to see where leak is actually from.
    Which model do you actually have? I recall @Cooper recently re-jointed his on a 6 pot and I have some pics of my 4 pot that may help?

    If you need some help with the oil leak I can give you the procedure for changing the oil housing gasket.

    Cheers for the help guys it's the 1.9 4 cylinder I'm sure. The last time I changed an oil filter it was under the engine and a simple screw off and screw the new one on haha. Bmw engines are new to me. I'll check out that link @jonco cheers

    Derek, I have the 6 cylinder so of little use to you sorry! I didn't know you had the 4 pot. Nevertheless I will upload the file here for you to grab as it might give you some idea what you are in for! This is for the oil filter housing gasket [the whole part that attaches the oil filter part to the block]]

    It should do - works for everything else - if you want to pm me your VIN - I'll have a look for you. It's normally 2 capital alpha followed by 5 numeric.

    Small update. Had the car in the garage again yesterday to look for the leak. After taking out a few items in the bay and spending about 2 hours cleaning oil from everything I found the leak.
    Oil filter housing has a big gap at the top. Now I'm not sure if it should look metal on metal or if you should be able to see the gasket? Away down south with work next week so the cars parked up untill next weekend :(

    Sorry I am late to this but normally it is either Gasket number 6 or the large o ring on the filter screw on lid, if however the screw on lid is not sealed correctly, it could have the wrong size filter in it.

    Replace number 5 and 6 and your problem is likely to be resolved. Good luck and keep us posted. Cheers.

    So as this seems like quite a big job to do I thought I'd get a price for someone else to do it. Been quoted £150

    But the whole point in me buying the car was to get my hands dirty and learn my way about the car

    So next weekend my job will be to replace the gaskets and do a full oil change haha.
