This is the main tube/hose assembly from the oil trap to the fresh air hose

When working on a breather system overhaul it is vital to inspect all pieces of the system including the hoses. Breather hoses have been known to fail causing issues similar to a failed oil trap. Typically we recommend replacing all hoses at the same time along with the oil trap for best system service life and performance.

If you are installing this hose separately please view the information below.

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

Genuine Parts Fit The Best, But Need Copper Washers

I recently did a complete PCV replacement on my 2001 XC70. I ordered this hose along with the kit. Both works well sine all of them are Genuine Volvo parts. One thing worth mentioning is while replacing this hose, it is better to replace the copper washers at the same time. It needs four of them. They are not expensive but it is hard to find the right size in the local auto parts or hardware stores. I did my PCV job on a weekend. I wished FCP bundled washers with this hose, so I could finished the job without rushing to my local Volvo dealer for them on Monday.

Some of the reviewers above may have been rewarded for their positive & negative reviews. We don't hold anything back.
