Oil Pump Failure
my '03 falls in the VIN range
she has 105K miles
I am the second owner - I don't have any previous paperwork that shows this has been serviced.
carfax/carcheck does not show this in its reports .
Is there a visual inspection I can do on the chain cover to determine if a pump has been replaced?
Is the redesigned -deeper cover - only for 2004's or will it also fit a '03?
Thanks all.

As far as I know the '03 and the '04 take the same front engine cover.
I do not know if you can tell just by looking at it if it was replaced or not.
I suppoose that if it is cleaner than the rest of the engine then maybe.

Is it possible to install the 4.0L long block with low mileage out of a 2002 DII in a 2004 4.6L DII.
I have access to a 2003 with 38 K Miles - blown engine, that has been sitting for a while.

Actually no you can't put a 2002 engine into a 2004. Emissions require that the donor engine be at least the same year or newer than the vehicle. A 4.0 in a 2004 will never pass emission inspection.
In North Carolina, the state DMV has independent shops running the inspections.
All they do is plug into the OBD II connector, scan for fault codes and pass or fail a car.
Not sure how anyone can tell if it is a 4.0 L or a 4.6 L if it passes the emissions testing with no fault codes.
Will see if I can get the 2003 with the bad engine and do the swap with a 4.0 and will let you know the outcome.

Looking thru this thread - as I am shopping for a Disco II and have a few 03 candidates...I am curious.
If there is no exhibited problem of oil-pump failure by a certain period...is the normal deduction that the engine was not affected, even if within the range?
thanks in advance,

Yes, generally the oil pumps went out under 60,000 miles, depends on how the truck was driven.
Now keep in mind that the front engine cover and oil pump could have been replaced when they showed signs of failure and you would never know the difference.
So if the oil pump went bad on the first owner at 50,000 miles and was replaced, then you can expect the replacement oil pump and front engine cover to go bad around 100,000 miles and so on.
So...as a general rule it is suggested that a preson avoids a 2003 Land Rover Discovery all together.
