I just picked up the only Mann filter of this size in stock at Advance in Savannah. It was not on display, and was sitting in the back. The box was shelf worn, and the red Purolator logo faded out. Filter inside nice and new. $8. They must not move very often. They did say they can get them usually in a day or so. So the on-line inventory worked this time for Advance (you can see their stock and price from home before making a run into town from the ranch). Can't wait to put this honken' thing on the Disco. Will post pix so people can judge clearance for themselves. Box says made in Mexico (I think that is just the box) and filter says made in Germany.
Thanks for taking the last filter in Savannah!
I did my first oil change with our new Disco and was all excited for this HUGE filter. I had to settle for the Mobil filter with Rotella 5/40 synthetic. Oh well, I guess next time I'll order the filter a week or so before from Advanced Auto Parts. Also I'll have the advantage of seeing how they run in everybody's trucks. Take care.Cheers,
Gabe

It's going to come gushing out as soon as you crank the old one off. You are in for a fun messy time I bet.
I would plan on having plenty of oil on hand just in case.
If you have a standard 4.0 Discovery, the filter does not actually have a "Housing" it just screws on a projecting threaded post on the bottom of of the engine at the front. I do not consider that to be a "Housing" like some of the older engines had.
When you remove the old filter you need to ensure that the old one did not leave anything still on the post or surface that would allow a leak. Also ensure you coat the built in seal of the new filter with fresh oil before installing. If you still have leak issues, you may have a slight nick or worn spot somewhere that is not properly sealing.

He made the very good point that with the higher bypass valve setting at cold startup or when clogged your bearings are going to be starved for oil longer than with the 8-11 valve setting specified by Rover.
The higher valve setting will cause a greater pressure differential for a longer period of time, so less oil going to where you need it.
Certainly nothing wrong with a larger filter, but I suggest sticking with the factory bypass setting.
