Thread: 2.7L Oil Pump Failures

All D3 are susceptible but they fixed the issue by the D4 release.

Is this potentially applicable across the range of D3 and D4, or is it something that was actually nipped in the bud at some stage?

Pre MY09 is no good - change oil pump housing at belt change
MY09 onward is ok
Tighten tensioner to specific torques only

Pretty sure that would be the pulley mount failure on the early 2.7’s when doing a timing belt change and not upgrading the oil pump casing to the later version.

The main failure years are 07/08MY. Prior to that they are less prone to failure but they can still fail. 07/08 have the weak cam belt pulley housing at the top of oil pump and post 08MY have fixed the issue. If you now order the pre 07My part number and the 07/08 part number from Land Rover you will get the new oil pump.

Of interest there are some but very few failures prior to the first cam belt service - most failures (but not all) fail soon after changing the cam belt so may indicate there is some thing related to changing the belt = possible development of a crack or over tensioning the cam belt guide - but whatever it is weak and then newer one is beefed up.

If you go to a LR dealer or Indy they will charge you about $400 for the new oil pump but if you go to Ford and get the exact same Territory part it is about $170 - noting some of the associated seals etc actually come in LR bags.

As the mount is on the pump its one and the same.

Here is a photo of the difference

Ends up being a good preventative maintenance task when ever doing a timing belt change even if you have the updated oil pump fitted.

From what angle as the tensioner should not snap off again? New seal or oil pressure are you thinking?

Mine was replaced along with water pump but next time coming up I’m thinking water pump only.
