Customer statement / workshop findings
•
Car requires engine replacement
•
Car requires replacement part for crank case ventilation system
Technical background
•
A change to the engine crankcase ventilation system was made at VIN SJAAC2ZV2JC017261. Service replacement engines will be supplied with
this new engine crankcase ventilation system for all applications. Other than the visual differenced in the crankcase ventilation system the new
supplied engine is interchangeable with the unit removed from cars pre VIN SJAAC2ZV2JC017261.
•
Careful consideration must be made when selecting parts from ETKA on cars affected by this change
Production change
Change as described above from VIN SJAAC2ZV2JC017261
Measure
–
Car requirement
Practical consideration
Car pre VIN SJAAC2ZV2JC017261 that
requires a replacement engine
Supplied new engine will have different crank
case ventilation hardware but will be a direct
replacement engine no changes required
A future event necessitates that a car pre
VIN SJAAC2ZV2JC017261 that is now fitted
with this replacement engine requires one or
more of the parts that make up the crank
case ventilation system
Do not use the cars VIN in ETKA when
searching for these part, the part numbers
for the new crank case ventilation system
are found in the post VIN
SJAAC2ZV2JC017261 parts frame
Car pre VIN SJAAC2ZV2JC017261 that
requires one or more of the parts that make
up the original crank case ventilation system
These parts are no longer available –
therefore the complete crank case
ventilation system (see Parts information
section) for the engine crankcase Bank 1 will
require fitting. Note this will require engine
and gearbox removal
