Engine Crankcase Breather Hose for Volvo

This Genuine engine crankcase breather hose, part number 30720098, routes crankcase vapors between the valve cover and oil separator. It is a direct-fit emission control component for select Volvo applications, including Volvo XC90 and Volvo S80 models.

Key Features

  • Genuine OE-style engine crankcase breather hose
  • Part number 30720098 for identification and ordering
  • Used in the crankcase ventilation system
  • Connects the valve cover to the oil separator
  • Fits 2005-2011 Volvo XC90, N/A
  • Fits 2007-2010 Volvo S80, N/A

Detailed Description

Part number 30720098 is an engine crankcase breather hose for the emission control and crankcase ventilation system. It is specified for the valve cover to oil separator connection on 2005-2011 Volvo XC90 and 2007-2010 Volvo S80 models. If you are replacing a cracked, hardened, or leaking breather hose on a Volvo XC90 or Volvo S80, this Genuine hose restores the intended vapor routing path in the crankcase ventilation system.

What It Helps Address

  • Crankcase vapor leaks at the hose connection
  • Oil seepage caused by a damaged breather hose
  • Rough idle or drivability issues related to ventilation faults
  • Check engine concerns tied to crankcase ventilation flow problems
  • Visible hose cracking, splitting, or collapse

Installation Notes and Tips

Verify the valve cover to oil separator routing before installation and compare the old hose to part number 30720098. Inspect adjoining ventilation components, clamps, and seals for wear, since a new hose will not correct damage elsewhere in the system. Confirm the vehicle application by model year before ordering.

Quality Assurance

Genuine parts are built to OE specifications for the listed Volvo applications. This part cross-references no additional part numbers in the provided data.
