Oil weeping from everywhere

Here is a case for the experts among us.

My 80 with a 1HD-FT engine recently had a gearbox, injectors and injection pump overhaul. Since then - but this might coincidental - it is losing oil from mainly the EGR valve and along the block below the air inlet side around cylinder #6. It has had low oil pressure indication for as long as I have owned it. I can feel no pressure on the cranckcase, when I take out the oil dip stick and have not noticed a big change in the oil level. There is some weeping from the PCV hose as well - both at the cam cover and the air filter sides. The engine runs smoothly though. I will post some pics below. For some reason 2 are in the wrong orientation... Sorry for that

I am trending to a turbo related issue - anyone with another idea ? Thanks for any input.

That is a lot of oil. Some is originating from the crankcase breather, they nearly all do it but there could also be some from the turbo. Remove and flush out the intake pipe from the filter housing to the turbo and maybe fit an oil catch can in the breather hose from the rocket cover which will eliminate most of the oil upstream of the turbo.
Also check the rocker cover gasket for leaks.
I removed the EGR valves from mine some time ago and blanked off the ports. If you remove the crossover pipe you'll probably be horrified at the amount of thick black crud that's built up in there.
Do you get any oil smoke on acceleration or under power? This could be from the turbo.
Removing both the rubber air inlet and outlet hoses from the turbo and starting the engine can reveal any oil leaks from the turbo seals. Holding a piece of stiff white card in the airflow from the outlet will show any oil being blown out.
Obviously be VERY CAREFUL not to let anything fall in or get sucked into the turbo inlet or engine intake as it won't end well.
