Where do these things leak oil from? Just parked in front of my grandads and noticed a few small patches, and there's drips on the undertray underneath, so I'll go over it tomoro, best places to start looking?

Rocker cover is a favourite, but could be anywhere.

Oil filter housing where it bolts on to the block, cam cover gasket, power steering hoses where they connect to the reservoir, all easy enough to fix

Depends on a few things.
IMHO it could be one of a few things.
1) Rocker cover gasket
2) Oil filter cap sealing ring ; this is likely if the person was lazy who changed the filter (i.e didn't change the seal at the same time) or it's not had an oil change for a while
3) Power steering pipes.

If it's rocker cover you will likely have smelt it burning off on the exhaust already.
If it's oil filter cap you will see spewage around the top of the housing.
If it's pas fluid from the res it will be red.
If it's oil filter housing, the most likely, then you'll not be able to see anything but the seal is a fiver from bmw and it's worth doing regardless.
It could of course be any other pipe or seal as well but those all mentioned are the common ones.

He had a passat thread on cgti Haha yes the old Passat got sold to a guy on here a few months back, it's gone to a good home, last I heard was it was going in to get all the paint sorted. Running a BMW e39 530i and a mk2 Honda jazz (grandad reputation but they're brilliant little cars) now after baby number two arrived in April :-) |

I just paid the bill for an oil leak repair on my wives e39 528i.
Things that are replaced;
Sump gasket and Dipstick tube hose.
Unfortunately I did saw some new/fresh oil drips on the drive way.
It might be some oil and degreaser that were still "hanging" around and found their way
down.
Will need to keep an eye on this.
We had the rocker cover done a few months ago.
Good luck

Goin up to nose shortly, will report back. It's definetly engine oil, I've not driven it in a while and my grandad has no sense of smell whatsoever so could be the rocker gasket, it's also due a service so I'll get hold of the filter and seal as well.

Have a look down the passenger side of the engine block, behind the alternator, if it is wet down there then it's likely the oil filter housing. Might need a torch as the intake manifold is a bit in the way.

Had a look, straight off the oil filter housing was soaked, also looks like a small weep from the rocker cover. So will crack on with that in the next week. Thanks guys  |

I've had three e39's, they all leaked oil! I would do the rocker cover and oil filter housing but if it isn't gushing it out I wouldn't worry about chasing leaks to much if I were you. Edit; OP; I've seen your avatar pic loads of times but only just now realised it's a 2 door, awesome! |
