Dry off all that fuel from the top of the injectors and leak off ppes. then see if it returns.

I had a similar problem on my 2015 model, and that was back in 2017 when it was still under warranty. Took it to Peugeot dealer and they insisted I pay them £250 to "investigate" I might get the money back if they decided it was a warranty issue. And mine had pools of fuel.
I sorted it myself, I found a pipe from the fuel filter was very clost to the head and I managed to get a shaped bit of plastic (gutter shaped) pushed down behind it to shield it. It's not shown in your pictures, just off to the left, but it was wrapped in black foam sheet. Head is dry now and has been since I did that.

 

Thanks for your reply Brilec. So you think the pipe with foam around it is leaking?

That seemed to be my problem as it hasn't been a problem since.

 

Still under warranty, then take it to them.
If not, you need to clean all the oil off with a suitable degreaser and then watch for the leak, could be a valve cover or an injector(s) seats, leak off (as mentioned), would be my thoughts initially. Assuming no DTC's or other issues happening.

Helps if you provide the Engine Designation Code from positions 6,7,8 of the VIN.

 

Thanks for your suggestions. No warranty. The engine is BHZ. No lights or codes

 

Likely be identical to a (at least for engine related components, possibly more)
PEUGEOT 308 (T9) 1.6 HDi 120 DV6FC (BHZ) 2014 - Onward
might be useful to know this is likely.

These are both covered in Peugeot servicebox online for OEM parts and information. (can be paywalled access, never sure how it works, I don't use it)

 

Mine is doing same, have you managed to find the fix, rocker cover gasket and fuel return pipes are changed twice but oil is still pooling around the injectors.

 

Just thought I wold help put you all out of your misery....

This fault has a TSB and is very common on certain batches of engines.

The leak originates between the cylinder head and the cam carrier. Something about not enough sealant there from factory. Or badly applied. Have had 2 in the garage recently for this.

Not to be mistaken for the seam between the two halves of the cam carrier, this is the seam between the carrier and the head.

Obviously you have to remove the carrier and cam to clean and reseal so might as well treat it to a timing belt and pump at the same time.

Good luck

 

Where I've drawn the red line is where it leaks. You can often see it bubbling with a good torch while the engine is running.
