It could be a few things, but I think you will find that is an engine oil leak.
It looks to me that it is coming from around the bell housing so is above the gearbox. Rear camshaft oil seal, rocker box gasket, or a leaking fuel pressure regulator would be my checking points. |

Hi, I had a similar oil leak which was traced back to the half moon on the rocker cover gasket.
At least a cheap fix. |

Thanks guys, it's the only leak I have on it for now, hopefully the chaps at the garage during the service will be able to trace it back.

I spent several days looking for the start of the leak. Took the lower engine cover off, which is an event by itself, cleaned everything I could reach with degreaser. Took it out for a drive to get the oil flowing and left a long trail of diesel behind me as I must have knocked the pipe loose on the fuel cooler.
Now with everything covered in diesel had to clean it again. Finally found the leak in the centrifugal oil filter housing. Replaced the o-ring and sealed it tight and leak has gone. Still need to replace lower engine cover. Need to find an easier way to do it. Steering box leak solved with a bit of brake fluid in the mix. A good couple of days working on the car. |

How does a little brake fluid in the mix fix a steering box leak? Thanks 2006 90 originally registered in Italy

I discovered the tip on this site.
Only put a small amount in. I think I used two cap fulls I believe it softens the rubber seals. Certainly has stopped the leak |

Depending on the type of brake fluid I could believe that it makes the seals swell, which might stop a leak. My understanding is that the when seals swell they are in the first stage of breaking down, but I may be wrong.
I can say with some confidence however that it is something I won't be doing unless much more supporting evidence that it is a good practice comes to light. |

I don’t suggest that it’s good practice. But if it means that I can get a bit more use out of the existing part whilst I gather the funds to purchase a reconditioned one then it works for me.
