Turbos do not have a PCV valve 850

They have a PTC, which is on the intake air pipe just before the turbo. There is an electrical connection. The PTC tends to get carbonized(?) and when it plugs, it will cause high crankcase pressure.

To clean it, be prepared to take the intake hose out of the engine bay. It is literally a pain in the back, bending over the rear of the engine to get the clamps off. Harder still is putting the hose back on.

I used a very small screwdriver to scrape out the PTC, along with carb cleaner. Volvo does not sell a replacement, it is part of the intake and you would have to buy the whole section of pipe.

The oil separator is a different story. It is under the intake manifold and is a 5 hour job to replace.
