My 1998/99 Volvo S80 T6 has an annoying oil leak that I can't find. When I originally bought the car ([sm=bs.gif] ) it had an oil leak that occurred a week later. It was found that the breather box was leaking and this has to be cleaned out / replaced. Now I have another oil leak that is persistant in it's nature and have no idea if it's the same part of something different this time.
Giving a description of the fault, I can drive the car from point A to point B. On some occasions after the car has been parked there for a day (i.e. while I am at work) I notice that there is a puddle of wet oil underneath my car. This puddle is evidentally from my car as the parking spot(s) I use have old oil drips here and there but have since "dried" up.

The puddle is about a rulers length wide by about a 1/2 a ruler's length long. It primarily appears on the drivers side of the car (note this is right-hand drive car as I am in Australia) about 10-12 cm in from where the driver's wheel would sit. It never leaks anywhere else except for around there, so I know it's on that side of the engine.

As a result the undertray gets really oily as it is leaking this oil from somewhere. Any ideas?

 

Couls still be the vent box or it could also be the front engine seals leaking.
