Just so you know how this whole operation turned out. Why the car, even after a complete engine overhaul and turbocharger replacement, was still pushing oil into the hoses. Well, the answer is simple: the cylinders were rebored with new pistons, and the car wasn’t properly broken in. That was the whole problem. It takes about 4,000 km after a rebore for the oil consumption to stop. I didn’t know that, and no one thought of it. As the car was driven and kept pushing oil through the hoses, the amount gradually decreased, and eventually it stopped pushing it into the engine cover. Because after the rebore, there was high pressure in the engine, there was clearance, and it was throwing oil through the turbos into the hoses.

So yes, everything can be fixed—the points I mentioned here are correct, since the car has done about 9,000 km since then and runs fine. I’ve already sold it, as the RR is simply a money pit. Good luck to anyone who takes it on.

Ok thanks at least you got to the bottom of it. Total money pits I’ll make you right there. I’ve got a different problem to where just fitted a running secondhand engine with reco turbos and both intercoolers filled with oil then into the air intake so got another problem lol

No, you don’t really have a different problem. There are two possibilities: either you have the same issue I had – the engine you bought is simply worn out, just like mine was – or the turbos you bought are bad. With rebuilt turbos that’s a common problem, which is why I bought brand-new original ones. It’s also possible that your separator filter is clogged, that can happen too, but I don’t think that’s the case here.
