Title (customer effect)

Volvo Chassis - Crankcase Venilation ( CCV ) Oil Leaks - US14 Emissions And Newer

Cause

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 the lower housings on
chassis builds between January 1, 2014 and January 26, 2016 with D11, D13, and
D16 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.

Solution
Should there be a report of this nature on a chassis built after January 1 2014, do not
disassemble the CCV. Remove the inlet tube assembly and carefully replace the O-ring
at the quick connect fitting with part 85148758 using an O-ring pick. Be careful to not
scratch the plastic quick connect housing with the O-ring pick during this procedure as
this may cause an oil leak. Return the parts through normal warranty procedures if
requested. If it is determined that there is a leak at the housing other than the inlet Oring, the complete 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. NEW - If the quick connect fitting is cracked or
breaks on disassembly, replace the complete tube assembly. If the collar on the CCV
inlet is worn or broken at the locking lip, replace the complete CCV assembly.
