Not sure if it helps but this is out of the official LR "Discovery 3 - LR3" manual for the 2.7 litre diesel.

Not sure what went wrong but the extract and picture that I pasted isn't here?
Words below:
Oil Filter
The oil filter is a replaceable cartridge installed on an adapter in the centre of the 'vee'. An internal bypass facility permits full flow bypass if the filter is blocked.
NOTE :
In service care must be taken when removing the oil filter to minimise oil drips and spillage into the engine 'vee' and cam covers:
- Do not use air/power tools
- Unscrew oil filter cap 4-5 turns
- Leave for a minimum of 1 minute to allow to drain
- Remove cap, ensuring minimal oil spillage
[*]Replace oil filter element into the cap (can only be fitted in one direction) - Replace cap and torque to specification.
