Volvo PCV Breather System Kit - Genuine Volvo 519055

NOTE:

• Commonly replaced due to a known "Whistle" coming from engine which is caused by a damaged vacuum diaphragm integrated into the oil trap.
• New Genuine Volvo oil filter included with new breather box.
• The dipstick mounting bracket and two cable brackets attach via bolt holes that are not threaded on this new housing. Because the hardware is steel, it will self tap into the new aluminum housing.
• Depending on the procedure for your vehicle, you may also need to replace intake manifold gaskets x5 31331885 and throttle body gasket 30637439 (https://www.fcpeuro.com/products/hose-clamp-12-20mm-9mm-wide-mh6), be very careful to apply minimal pressure or risk breaking plastic hose fittings.
• If you want to add hardware, the correct bolts are 4x 985322

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
