Product Description

Internal combustion engines aren't perfectly sealed on the inside: as every cylinder fires, a little bit of combustion gases escape down in to the crankcase. If you've ever had your oil cap off while the engine is running and you feel little puffs of air in time with engine rotation above the opening, you're seeing this "blow-by" firsthand.

Enter the PCV, or "positive crankcase ventilation": by hooking up hoses and valves to the engine's air intake, these gases can be sucked out of the crankcase by intake vacuum and burned inside the engine. Capturing and burning these blowby gases not only makes the engine runs cleaner, but keeps pressure from building up inside your engine; a failed or plugged PCV is the root cause of many oil leaks, as that pressure buildup will eventually start pushing seals out.

Modern Volvos draw a lot of vacuum through the PCV from the intake, so a healthy, self-regulating PCV is important not just for preventing excess crankcase pressure, but also for keeping crankcase vacuum from getting too high, which can cause squealing noises as air gets sucked in past the PCV diaphragm or even other seals deeper within the engine like the turbo oil drain or dipstick tube.

This Genuine Volvo PCV/Oil Trap Assembly is just the thing to keep your seals safe and leak-free. If you've got squealing or chirping noises at idle, or if you can feel constant suction from the disc-shaped diaphragm cover, pop a new PCV assembly on to your engine to keep on going.


About Genuine Volvo

Everything IPD supplies under the "Genuine Volvo" designation are the factory original Volvo parts. These are the same quality parts that you will get in the blue Volvo branded box from a dealership. All Volvo supplied Genuine Volvo parts are made to specifications by Volvo and under their strict quality control guidelines.

Volvo relies on high-quality OEM manufactures such as Lemforder, Behr, Sachs, Bosch, Valeo, Siemens, VDO, Corteco, and many more to maintain its dedication to quality and safety.

IPD is the exclusive North American distributor for Genuine Classic Volvo parts outside of the Volvo Dealership network. We are proud of our Volvo heritage dating back to 1963, a reputation that is unmatched by others in the industry.

Many may not know this but Volvo in Latin roughly translates to "to roll".  The company was founded back in 1927 by Assar Gabrielsson and Gustaf Larsson as a spin-off from ball-bearing manufacturer SKF.  While the Volvo logo looks like the biology symbol for male, it's really the Swedish symbol for Iron. With a nod to its heritage in alloys, Volvo chose a logo that depicted a ring bisecting at one o’clock. Today Volvo is known around the world as one of the most iconic brands known for safety, longevity, and its enthusiast following.
