Volvo PCV Breather System Kit - Genuine Volvo KIT-534914

Be sure to check the fitment guide below for specific details tailored to YOUR model. Your engine serial number is located on your timing cover.

FCP Euro offers this Volvo breather system kit at an affordable price without having to sacrifice the quality that you and your Volvo deserve. If you notice that your Volvo does not operate with the same level of power it once had, or if your exhaust is emanating an unusual odor, this may be related to your Volvo breather system. This kit will replace rubber tubing and fittings that become brittle with age. The tubing can also become restricted due to built up oil deposits and sludge within the hoses. This kit includes a new oil trap, all of the breather hoses, an intake gasket and all of the necessary hose clamps.

What causes my breather system to fail?

• Wrong oil grade, quality and/or viscosity
• Vehicles driven too many miles between oil changes
• Vehicles frequently driven short distances with many cold starts
• Excessive idling
• Fuels of low quality or with high alcohol content
• Additives added to oil or fuel
• High ambient temperature
• High air humidity

What are some of the symptom’s I can expect if my breather system is clogged?

• Illuminated oil pressure lamp. – Due to clogged oil suction strainer to oil pump or oil filter
• Illuminated Check Engine Lamp- Due to incorrect engine fuel trim level parameters
• Noise (whistling) – Noise due to high pressure in crankcase. This noise will stop if the oil filler cap is removed.
• Poor Drivability- Clogged crankcase ventilation can reduce the engine performance
• Uneven / Oscillating Idling- Caused by clogged crankcase ventilation
• Oil leak- From engine seals due to restricted crankcase ventilation
• Noise (knocking)- Low oil pressure can cause premature bearing wear and lead to internal engine component failure
• High oil consumption/noise from Turbo
• A damaged bearing or seal in the turbo due to lack of oil as a result of oil consumption.

What can I do to check for it?

• The first step is to inspect the oil filter to see if it is abnormally dirty. An abnormally dirty filter is easily recognized by its thick, black deposits
• If the engine has a problem with carbon deposits, the passageways in the engine block and oil trap may be completely or partially clogged. Remove and check the oil trap, hoses and their passageways in the engine block. There should not be any major collections of carbon deposits in the hoses or in the passageways in the block.
• Drain the engine oil. Remove the oil pan and check the oil pan and crankcase for deposits. Normally, there should not be any deposits. Also check the oil suction strainer on the oil suction line for contaminants and deposits.
• Use a low caliber Vacuum gauge to check for positive pressure through the dipstick tube
