Black smoke and oil in intake pipes

Lots of black smoke on hard acceleration and fair bit of oil in the turbo to manifold pipe.

New turbo fitted and new silicon hoses still not cured it, oil appears to be coming out the pcv system top pipe then down to in front of the turbo.

It’s like the oil is syphoning out the sump I can’t see any blockages in the pipes as Iv blown airline down them all ?

Any ideas anyone

After removing the pipe from the oil separator to the turbo no oil comes out but the oil still leaks out the front of the turbo to intercooler pipe

Check that the oil separator is properly located in the crankcase rubber seals as if not it allows the inlet / turbo to suck air in through the gap and that draws oil mist out of the engine and will devour oil at a surprising rate. I had few nervous days when this happened to me until I found that the separator was siting proud of the rubber seals. Once properly sealed and oil cleaned out of the system all was well. However do keep checking your oil levels until you confirm it is sealing because I was losing a litre every hundred miles, so it will not take long to empty the sump!

Removed the engine as the turbo has oil leaking out both sides looks like the new turbo could be faulty

Well I have found the problem

A hole in each inlet manifold cam cover oil was getting sucked up through the holes.
