Noticed this a while ago, but haven't got round to investigating yet 
Wherever it's coming from, it's gathering on the lower right, adjacent to the air on pump. Might actually be the same as TB's leak?
I'll be having a closer look soon, but thought I'd ask for some pointers in case someone has come across this problem before.
Also noticed low coolant level and a 'puddle' on the plastic under tray  I think it's coming from one of the extra pipes for the lpg so I'll have to check that too, but it should be an easy fix 
There always something

Looks more like water? Condensation from air-con pipework?

[jonny2112]

Mmmm. Aircon not currently working (needs new condensor) and there is a noticeable smell of burning oil after driving. Nothing to say those are related though.
On previous occasions the mess has not been as 'fluid' as what appears in the photo, so you may be right.
I'll need to sort the coolant leak and top up all fluids taking an accurate note of levels, clean this area well, and keep an eye on it!

Camcover gaskets and/or blocked breathers.

I don't think the aircon is able to drip on the exhaust manifold (doubly so if it isn't even switched on and working)

Cam covers are on my list, but the plug wells were dry last time I checked, at the start of August.

dont forget cam seals they seem to wear quicker on exhaust cams -

Hmm, I wonder.
The front cam bearing cap also retains the camshaft seal. The cap needs to have a tiny smear of sealant applied near the front to prevent oil from weeping out of the joint.

I wonder if the mystery oil leaks (this one and TBE) are from the front cam bearing caps? 

[jonny2112]

That would help explain the leak to the front, rather than the sides 
Can these be checked in some way?

I've checked, DLK has checked and Marks DTM has check. My cam seals, despite being 210k (certain we didn't change them when we did the HG a few years back), dry as a Saudi bar.

The only wat I can see to check if the cam seals are leaking is to remove the cambelt cover. You will then see through the camsprockets where the orange/red seals are and also down the edge of the cambelt backing plate.

[Darth Loo-knee]

It isn't power steering oil is it?

[jonny2112]

Hoping to get the cambelt done shortly so should at least be able to take a look at the seals.
Never thought of power steering fluid. Accurate oil dipstick reading should indicate if engine oil I guess, and a visual inspection ( when the bl@@dy rain stops ) may show if it's dripping, running down, leaking out, etc. if you know what I mean

Can you see the joints between the head and the front caps with the cambelt backing plate in place ?
