the turbos arnt the best is replaced with a chinese one, need to do a oil pressure test at the oil pressure sensor and see what it is when its playing up, the oil pickup o rings have faults, it could also be a wiring fault though

low oil
oil contaminated with diesel
damaged oil pump/s
Strainer as per robs post
After market oil filter with no anti drain back.
Should always wait for oil light to go out before revving engine
What mileage?

if it was mine i would just run a machanical oil pressure gauge in it to make sure as it has been a problem for a while, sounds more electrical than machanical if you have had it checked out and its still going would have run a bearing in the engine by now with no oil pressure
