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.
Its a flame trap it separates the oil from air. it becomes clogged fyi so regular maintenance is needed.
It does however have a box on the front of the engine below the intake that can clog and cause oil leaks. It is called a number of names, oil trap box, oil separator box, etc. The turbo 5 cylinders do not have pcv valves. Dan
its a flame trap. look up bay 13 at www.volvospeed.com on how/where
check PCV, oil separator under the manifold and all pcv vacuum lines.
Strictly speaking it doesn't have a pcv valve it has a pcv system. Generally the part that gets plugged is the oil trap. Pretty much the whole pcv system is under the intake manifold and you have to remove it to do any work. Look on any sight that sells parts for volvos and they'll probably have a diagram of the system.
The PCV valve on a 2004 Volvo S40 is located on the engine crankcase. It is a small rubber valve.
The part that needs replacing is called a flame trap. This is an inexpensive component changed at service intervals. I assume that you refer to 500 US Dollars, and not pounds sterling. It still sounds way too expensive to me for a flame trap. I'd take to the car to a Volvo retailer, or to another specialist for the work to be carried out.
The PCV valve is located in the engine area on the 99 Volvo S80T6. It is important to carefully study the user manual which has an illustration of the same.
Behind the intake manifold!
There is no pcv "valve" on the 2.2 but the pcv "system" keeps oil from getting into the intake. I'm trying to fix my 2.2. Oil everywhere.
pcv system is clogged up.
