I'm sorry, but if I type in Romanian, I won't even know how to say most words...I am lucky that I can still read
You have to take out the oil pans..both of them
Then drill the block for the oil return
You have to tap the engine (make threads for the fitting)
Fitting screwed on.
after that, all you have to do is put the manifold with the turbo on, and connect the hose on the bottom, and the oil feed which is on top.
