Oil leak help please

Click image to enlarge

Hi can anyone help tell me what is causing this quite bad oil leak please. it appears to be coming from a short far pipe just above the front axle/diff, sort of next to the starter motor (I think it is that). Hopefully this photo will show it clearly enough. It’s not the thinner longer pipe on the left, it’s the short one on the right and you can see the oil wet all over the crinkly pipe. I can send more pics but I think it is clear if you expand this one. It leaves a bad mess on the drive every day. The engine oil level stays on the max line. 80k miles on a td5. Thanks.

Thanks David, that’s helpful, I hadn’t thought it might just be diesel. I’ll catch some in a tub overnight and give it the sniff test. I’ve expanded the pic and circled the pipe, looks like a breather of some kind.

The drip is on your starter motor. Directly above it is your fuel pressure regulator. These can develop a leak so that fuel runs down, washing your engine as it goes. It looks like oil but will smell of diesel. Test it for smell. If not the fuel pressure regulator it can be the gasket on the rocker top. (The very top engine cover) which is easily spotted once you get the acoustic cover off. If it is the rocker cover you will need a new gasket and whilst doing it I would also renew the injector loom whist you are there.

...just to conclude this post, collected oil and no diesel smell, definitely gear oil of some sort. Now had it on ramp and there was a pin hole in the front diff casing. Sorted now and caught in time. Thanks for the input everyone.
