I too have a 2003 Disco that develops a ticking noise once in a while.
Does your ticking sound like my post on youtube?
If so it's an easy fix.

RE: TAPPING NOISE
ATF flush works.
Mobil-1 definitely helps.
Mobil-1 filter likely helps.
My tick comes and goes, mostly goes.
When I hear the tick I simply do an induction cleaning, then I follow it up with a Seafoam crankcase cleaning. And it's gone... meaning in suppression for 25,000ish miles.
My resolve: I simply drain 10oz of oil. Then I replenish it with 10 ounces of Seafoam. I start the engine and let it idol until the ticking stops (usually 30-45 minutes). Seafoam publishes a tech sheet that suggests driveing 100 miles, but I prefer to go the softer route idol+time.
When finished, the oil will drain out like water and the scum that is causing the lifters to stick will be loosened and hopefully drain out with it.
I replinish the oil, replace the filter and it's good. Another oil change at 1,000 miles to expell any residual Seafoam and grime.

RE: TAPPING NOISE
I have a 94 that has a similar problem. I have done the ATF, induction cleaning and seafoam in the gas, and still have the tick. In fact the motor ran worse after it all. I have not tried the seafoam in the oil so I might try that next. I actually think that the seafoam in the tank toasted the fuel pump. If that does not work then I am getting the heads rebuilt. Good luck with your solution.

RE: TAPPING NOISE
If that is your exact same tapping noise then you have lifter noise, you can drive it like that forever.
These trucks have hydrolic lifters, the only real fix is new lifters.
Keep using the full synthetic motor oil, change it every 5,000 miles and dont worry about it.
If/when you replace your head gaskets do new lifters at that same time.
I had a Chevy that did the exact same thing, thicker motor oil made the lifter noise go away.
My old Ford work van did the same thing too, over 100,000 miles later it still ticked and still ran great.
