Your dealer lied to you. There is no PCV on turbo models, no flame trap either! If the manifold pressure is too high, you would get leaks from the rear main seal or the oil cap or even the dip stick. I doubt it would cause oil to be burned in the exhaust. You have another problem. There is a PCT(?) on your engine which allows oil fumes to enter the turbo at the air intake behind the air cleaner down near the rear of the engine. It has two vacuum lines and an electrical switch attached at that point. Do a search on "PCT" and all will be explained. It is not an $800 repair! Change your oil to synthetic 10W30, it will absorb more heat without breaking down and smoking.

Your "dealer" should know Volvo has NOT used the PVC system for more than 10 years. There is however an oil seperator that connects to the air intake.On the NA engines there is a flame trap which consist of a small screen. The Oil seperator is located behind the intake manifold

Hi Pat,

If the PCV system is clogged, it will cause engine seals to be come unseated and you will leak oil. As far as the blow-by is concerned, work rings would probably be causing that.

I've never heard of a clogged PCV system causing blow-by, but that is not to say it could not happen.

Taking care of the PCV system on a turbo is not something I am familiar with, but that being said, I would think $800 is a bit high. If you're comfortable taking apart your intake, and removing the intake manifold, you should be able to get to most of the PCV "plumbing" to take care of it.
