P38 4.6 oil leak on front running out of ideas!

Hi all get quite a bad on leak on front of block, done camshaft oil seal rocker covers and sump
Pressure valve seems all good. It's the o/s of the engine not filter side also done filter and oil.
Am I right in saying there is a front cover gasket could that leak oil? Also would the head leak from there??
Thanks in advance!

Possibly the valley gasket rubber seal letting oil through. is the top of the water pump covered in oil?

+1 would say it is valley gasket front seal
