OIl leak on 3.6 diesel L322

[vbrab]

Did an oil/filter change on 3.6 diesel, all seemd to go well.
Went for a drive next day and about 100k's out noticed an oil smell when I pulled up.
On looking underneath could see clean engine oil dripping off underneath. Not heavy, but certainly oil where there had not been any previously.
Checked oil levels frequently on drive home, but level did not appear to drop much, and oil underneath was not heavy, but steady drip, mostly on passenger side of vehicle.
Checked around filter top side of engine, but no sign of leaking, removed filter checked seal, all appears to be installed and sealed correctly.
Jacked up and removed front passenger side wheel after seeing that oil appeared to come from around front suspension and to flow down from about underneath the air cleaner on that side. Oil did not appear to be running down from off "V" in engine (where filter leak would likely run from).
No oil leak signs topside, but oil appears to be flowing down from approximately area under where air cleaner box is, (See pics) and then blowing back under vehicle.
Can anybody suggest a component that might leak oil over that side of the car?
Is it possible I put too much oil in (was told 9 litres with filter, and dip stick appeared to confirm that) and that this leak is a consequence of overfilling (perhaps)?

Further checked, could see oil on underside of aircleaner box, removed it and can see that oil is throwing from front of engine, on to rear of both air intake pipes, on to cleaner and then working its way down.
Possible that I slightly over filled oil level and that made it easier for oil to flow out a front seal.
Just have to work out which seal has died.

That's got me scatching my head [bigsad]

Oil filler cap was secure ?

No diesel mixed with the oil ? The "O" rings on the return fuel lines do go and you can get a leak at the injector, also the securing clips can break. Could also be a cracked injector ; worst case.

Viton replacement O rings, and Jaguar injector clips are the go.

From exploring about under car and removing aircleaner to look in, oil appeared to have come from area of front crankshaft seal.
Also had my service person tell me that they have never had to do a front seal on 3.6 diesel, and many they service have done 400,000+k's.
Pressure cleaned car down and washed off "leaked' oil.
Put car on flat surface and let it stand for half an hour then dipped oil, even after the leak (which may have only been 300mls, but looked messy), the dipstick was still showing oil near the very top marker on the stick.
From this I conclude that I put too much oil in, and maybe it doesn't take a full 9 litres on a change as I was told.
I undid the sump, drained about 400ml, oil level is now between the 2 markers, and the leak has not come back (yet).
So hoping it was just that I put too much oil in, making it easier to leak out front seal.
