How to test the Volvo 850, S70, V70 PCV System - Video
The Volvo PCV system is one of the most neglected maintenance items on the I5 cars. Failing to maintain this system can cause major oil leaks. I blew one of my cam seals one evening and lost 2-1/2 quarts of oil in just 2 miles. If you do not know when it was serviced last, replace the system today.
This video will show you how to test the system on the Volvo 850, S70, V70 and other Volvo cars.

If someone buys a car and has no proof the breather box has been replaced, why would they replace it if it tests good? If there is no pressure building, it doesn't need replacement.
And the vacuum elbow on the side of the intake being torn won't cause pressure to build. In fact, it would cause any vacuum readings (or rubber glove test) to be inaccurate.

Hi RSPI, it sounds like your the 850 man to go to. I haven't a clue what I'm doing in regard to the forum and I need help with my 97 850 estate, where do I place my question, or how do I search for a forum user that may have had the same ABS dash light problem?
Sorry if this is the wrong place
many thanks

When I got my wagon the "big" test was, pull the dip stick with the motor running. If no smoke you're fine. Well, I had no smoke and a plugged system. Ports in the block were more than 50% plugged, EGR was clogged, and my RMS was leaking. So, my recommendation is to replace the system and know it's good. Why risk a $1,000 repair for a $150 kit? To each his own I guess.
