CCV Housing Inlet Tube, Replacement

VAH, VHD, VN
FSB 257-004, CCV Housing Inlet Tube,
Replacement
(September 2016)
VOLVO Trucks has received reports from the aftermarket regarding oil leaks at the CCV
housing inlet tube and at the split line between the upper and lower housings on chassis
builds between January 1, 2014 and January 26, 2016 with D11 engines. It has been
determined that the O-ring installed on the inlet tube is the source of the leak and oil may
leak down the back of the housing giving the impression that the housing split line is also
leaking.
Should there be a report of this nature on a chassis built within the affected date range, do
not disassemble the CCV. Replace the inlet tube with part number 22858729. Clean the
surrounding area to complete the repair. If it is determined that there is a leak at the housing
other than the inlet O-ring, the complete CCV assembly will need to be replaced as this is a
non-serviceable part. Do not attempt to tighten the split line screws on the housing or
disassemble the assembly as seals and repair parts are no longer available for this
component as they were on the older version of this component. If the collar on the CCV inlet
is worn or broken at the locking lip, replace the complete CCV assembly. Additionally,
Replace the CCV to cylinder block gasket any time the CCV assembly is removed.
