Not 100% sure about the '87, but there is no PCV valve on the 1986 Volvo 240 2.3L. Flame trap and Oil trap, but no PCV.
It can be a little expensive to replace the EGR valve on the 1987 Volvo 240 DL. The job takes about 1 to 3 hours and can cost as much as about 240 dollars.
No, they are not user serviceable

My friend has a 1982 Volvo Station Wagon 240 GL that needs headlights replaced, what is the best way to go about this and about how much will it cost?
It's better to go ahead and replace it.
