Hi, was out in my 2006 2.5 N52 today and was topping up the windscreen wash when I noticed I appear to have a slight oil leak from somewhere, see photo. Any idea where it could be coming from? What is the circular thing with the black cap on in it? - says on it that it should be torqued to 25.6 nm or similar?
There wasn't a huge amount of oil and looking down into the bottom of the engine compartment I can see a few drips but nothing major. It was enough however for me to be able to smell a slight burning odour when sat at traffic lights. I've cleaned it all up now and will monitor over the next few days to see if I can trace it. In the meantime, any suggestions appreciated......thanks!!!
