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
  • 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

This kit includes Genuine Volvo parts which are the same parts that you would receive from a Volvo dealership.

Dad Do It All

Well worth the price and the time to do it. My S70 was using quarts of oil a trip to work and back not to mention the puddle of oil under my car. When I pulled the old flame trap out, it and the hoses were so caked with sludge it's no wonder it was backing up. I have driven over 200 miles and not a drop of oil low.

A good kit with all the critical parts genuine Volvo. This is not a place where you want to use aftermarket hoses because this is not a job you want to re-do.

Great Improvement

Thank you FCP for the great service once again! My 98' V70 was throwing a code at 210K miles, P0172. After research, decided to check the vacuum hoses, and as suspected, that 'evil little elbow' on the passenger side of intake manifold was toast. Also, some oil was being forced out the top of the engine somewhere. As I have never replaced the PCV system, I went for it. Bit of a pain, but what a huge improvement in overall engine performance! My mother had a PCV issue on her 2000 XC, and it caused big issues with pressure pushing oil out the lower main. Don't neglect this maintenance! I'm lucky I went 210K before having issues.

Good kit. It was missing a clamp, so I was forced to reuse one of the original ones. It appears that the clamp is missing from the kit specification -- not just from my particular kit. Also, there were some extra parts; it appears that this kit is for more than my normally-aspirated '97 850.

Superfantastic to have all the parts needed, in one kit! No need to search for this, or for that. And, no parts forgotten, either. The on-line video helped greatly in making the job go smoothly and efficiently.

The kit included all the parts necessary to complete the job on my 1998 non-Turbo S70. The DIY video by FCP made the job real simple to complete. The only items in the PCV Breather System kit that I didn’t use were the Flame Trap Kit parts.

I have a 1996 850 GLT and FCP does not have a kit listed for my model. I contemplated ordering all the pieces individually, but I didn't really want to call the dealer and get a list of parts. Anyway, I decided to go with this kit, even thought it supposedly is for 1997 and 1998. My engine serial number is after 616631, so I figured it was the same one in the 1997. Long story short, everything fit like it was supposed to and I didn't have any issues. Perhaps this kit should be updated to include later '96 models...

The Volvo PCV Breather System Kit is a must if your Volvo has 150K on it. I installed the kit at 260K on my S70 and the performance was like an engine rebuild. The engine must "breathe" to perform well, and this kit gave a smoother running engine as well as cut out the oil leaking (from the resulting back pressure created by a clogged system) onto the top of the engine and down around the spark plugs.

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