3.2L Oil Trap S80 2007

While the car was being diagnosed at the dealer for the alarm issue they noted two other items that need to be addressed. The first is the oil trap. 31319642 for $250.62 and two hours labor, $481 + tax. I have found a video and it seems simple enough to replace. It appears to be the PCV system for the engine. My question is this, is it a problem if I ignore it on a 110,000 mile engine? Can it be soaked and cleaned?

    How long did it take to get that movement in the glove?

    How often do you plan on checking it in the future?

    Many techs are looking for what is likely to happen before your next service.

    I do not know how the techs check this - maybe they can connect a gauge somewhere.

    Why don't you ask the tech to let you now why he said that you need service on this matter.

    I talked to my family Subaru tech, and on their cars they change PCV valves on a regular basis as maintenance.

    The crankcase breathing system deals with crummy oil - it shall clog up at some time.

      The glove immediately was sucked down to this level.

      This car has always been serviced with Motorcraft synthetic blend motor oil and Volvo UEM filters. It never moves off the full mark on the dipstick between a recommended 7500 mile service interval and is still amber in color.

      I do not live near the dealer and have not called them back as to how they determined the need for this service.

    No responses...

    From what I have read, the oil trap needing service can be observed by there being extra vacuum in the engine. I checked mine today and there was no discernable vacuum at the oil cap or dip stick. There was no change in engine tone or RPM with either open. How does a Volvo dealer tell that is needs servicing? Is it just because mine has 110,000 miles and has never been changed?

    I think I'll leave it alone.

      The oil trap needs maintenance when there is NO vacuum at the oil filler hole or dipstick tube.

      The maintenance interval is quite variable and depends on driving habits, type of oil, oil change intervals, turbo or NA, etc. It was worse with the 5 cyl than the 6 cyl.

      So long as your system creates a small amount of crankcase vacuum, you are OK. Once the pressure in the crankcase goes positive, you are at risk of pushing out the cam seals or engine seals.

      To check for vacuum, remove the oil cap, wrap a latex glove over the filler tube and secure it with a rubber band, and start the engine. If the glove inflates, you have a problem as it should be slowly drawn into the hole.
