Issue:
Crankshaft/crankshaft bearing failure - TDv6 Diesel Engine.
Cause:
Low incidence of crankshaft failure are being encountered, caused mainly by incorrect location of the main bearing shells during assembly, or through rotation of the shells during normal use. A new procedure has been implemented to ensure:
- more rapid resolution of customer concerns, and
- greater visibility of failure modes in order to improve repair process and parts delivery.
Action:
For any suspected crankshaft/bearing failure, please contact your local Dealer Technical Support or FRED team for details of the enhanced customer handling procedure.
The list below summarises typical symptoms of crankshaft/bearing failure, but please contact your DTS/FRED team if in any doubt as they will be pleased to offer assistance:
a· Crankshaft is seized, engine cannot be turned either via starter motor or crankshaft pulley bolt.
b· Oil sump or engine cylinder block is holed, with oil leakage and/or metallic debris found on engine under-tray.
c· Engine makes a loud rumbling/knocking sound when running which worsens as the engine is placed under load. The engine oil pressure warning light may flash or be continuously illuminated, especially at low engine speeds.
========================================================================================
So long as your engine is the TDV6 mentioned above, then Land Rover have acknowledged that this is a manufacturing defect, and should have some liability for repair.
Hope this helps.
