Additional Technical Information

Common issues with Volvo PCV Systems:

There are a couple of things that get overlooked in the PCV system issue. The lifespan of PCV components varies widely based on operating conditions.


Usage: The PCV system likes to be used at higher RPM for long periods of times (like a trip on the freeway). It also likes higher temperatures to help vaporize the negative contamination in the oil and burn it through the PCV. But in the other direction, a car that is used in a cooler environment and shorter distances will load up and plug/fail the system rapidly. We have an employee who completely rebuilt their PCV system in their daily commuter about every 18 months, due to the cool/damp environment and a 7 mile commute on surface streets.

Wear: The contaminants in the oil are volatized and burned up by the PCV system. But, the amount of blow-by in an engine (the primary source of contaminants) changes dramatically as the engine goes through its life cycle. So, the amount of contamination the PCV system is required to handle in a 300k engine is dramatically different from the contaminants in a 100k engine.

Final: Kind of a combination of both of the above topics. The majority of contamination and plugging in your system happens during warm-up. This is why cars that are used for short distances need so much more PCV work. So you can’t really measure life cycle of PCV components in miles, but they are really measured in key cycles (temperature cycles).

Potential Product Fitment Issues

PLEASE NOTE: This PCV kit contains more parts than you will actually need to service your PCV system.

There are several variations of the PCV system on 850 non-turbo models. This kit includes parts for all these engine variations but will have some parts that will not be used on your particular engine application.  You will need to carefully note the parts that come off your engine so that you install the correct new parts back on it.

Many of the original parts for this PCV system are no longer available from Volvo.  We are using as many OE Volvo parts as we can source for this kit but there are some aftermarket parts included. Since many of the original parts are no longer available, You will end up having to improvise with some aspects of the installation.

Early cars with LH fuel injection typically use a vent tube that runs from the oil separator through the intake runners between cylinder 2 & 3 and runs up and over the intake manifold over to the black plastic accordian intake tube. When servicing the PCV, it is best to use the original routing as running under the intake can interfere with the variable intake runner mechanism.

Later Motronic cars typically use a vent tube that runs underneath the intake from the oil separator to the black plastic accordian intake tube.  The OE vent tube is no longer available from Volvo but we have included additional hoses that will allow you to cut the provided plastic vent tube and use it as couplers for the rubber hose.

Early and late cars use different black plastic accordian intake tubes. The tubes only vary in the angle that the PCV fitting connects to the tube.  The early style angles up for over manifold routing and the later style angles down for under manifold routing.  There may also be some variation with cars that have exhaust air (smog) pumps.
