2003 Discovery Oil Pump Issue?
#21
If you replace the oil pump you must also replace the front engine cover.
Replacing the oil pump and front engine cover is a temp fix, it will fail again.
The problem is a block defect, the oil pump is housed inside the front engine cover.
The dowel pins on the front of the block that the front cover mates to are out of wack and they cause premature wear on the front cover which inturn puts premature wear on the oil pump.
So, the only 100% cure is a new non defective engine.
Your engine is still good, bearing and what not wise, just the oil pump will fail again.

IF it is a defective block ther eis no way it lasted 90k with the original oil pump.
They typically fail in the 40-50k range.
Not all '03's are in the bad VIN# range, not all in the range are bad and not all out of the range are good.
There are even a very small number of '04's with this problem as well.
So...I would to a oil pressure test, then depending on how that comes back would determine my next course of action.
It may have been a fluke.

Can you do it yourself? Ya, why not?
You will need to remove the front of the engine, thats the water pump, crank pulley, any belt tensioner, maybe the power steering pump and whatever else is in the way.
Unbolt it, remove the cover, install new oil pump, new front engine cover, water pump...you get the idea.
The only special tool that you will need it a fan clutch removal tool.
It is a 32mm nut that holds the fan clutch on.
