    Oil leak, from this bolt?? 2000 540i

    I was looking for the source of an engine oil leak on the passenger side. It looks like it's coming from this bolt head, that's around the center of the block. Any ideas what this is called? I tried looking for it on realoem's diagrams but couldn't find it.

    See green circle(not really my car/engine):

    That's the coolant drain plug for that side of the block.
    Look on the other side of the block, there's one there too.
    Nice clean engine!

    What's that AN4 braided line for?

    Yep, that's the coolant drain plug. Your oil leak could either be coming from the valve cover gasket or maybe from the upper timing covers.

    Ah coolant drain plug. Of course. Thanks folks. I totally stole that picture since it was a clear shot of the block. It's from here:
