Tell us what you did, can't help otherwise. You must have missed a step or something.
1. How high did your raise the reservoir?
2. Took out the bleed screw?
3. Filled the reservoir until a steady stream (gush) comes out of the bleed screw?
4. replaced bleed screw?
5. topped of reservoir?
6. replaced reservoir in retainer clips?
7. started and ran the vehicle checking for leaks?
8. turned vehicle off and let cool then check for leaks again?

Do it this way:
Fill the coolant bottle to the full mark.
Warm up the truck until the temp is 1/2 way on the temp gauge.
Unhook the coolant bottle from the truck. It unclips.
Raise the coolant bottle very high.
Remove the cap from the coolant bottle.
Run the truck at 1,800 RPM for 8 minutes.
If the coolant spews out - STOP. Could be bad head gasket.
Coolant does not spew out - keep running the engine for 8 minutes at 1,800 rpm.
Bubbles will rise and just come out.
Coolant level will drop.
After 8 minutes, turn off the engine.
Replace the cap.
Clip the coolant bottle back into where it goes.
Open the cap.
Fill to full.
That's it.
Will not gurgle or make water fall sound after this.
This is how a Discovery I auto bleeds as the coolant bottle on a Discovery I is always the highest point in the cooling system.
Don't even mess with the fricking Bleeder screw.
Best of luck

You aren't kidding!!!! Get it up to operating temp then open the cap? No thanks! I've always done the system bleed according to RAVE and haven't had any issues.

I have had an on and off waterfall sound for a wee bit now. After 20 years as a LR tech then I have ALWAYSD followed the LR of bleeding the system.
A fellow tech suggested I bleed it a different way.
Raise the passenger side up high, I used a ramp
take the expansion tank and raise it up, i used the batter cover and supported it on there
with the motor cold fill the expansion tank until colant comes from the bleeder, keep puring it into the expansion tank and let the collant come from the bleeder for 60 seconds. close the bleeder
HERE IS WHERE IT GOT INTERESTING.....
Turn the truck on and turn the heat onto max heat and max speed
now rev the truck to 3500 rpm for 10 minutes. YES I KNOW IT SOUNDS WRONG BUT DO IT.
NO CAP ON THE RESIVOUR... ALSO SOUNDS WRONG AND AGAINST EVERYTHING I HAVE BEEN TAUGHT
after 10 minutes let the truck idle and then switch off.
place the cap on and return the expansion tank to it normal position, carefull as you will get over flow.
After i did this I have NO waterfall noises and lower temps.
I HASTEN to add that this goes against every thing i have been taught and goes against what LR says you should but I have seen this done to a 2002 and it worked the same as my 2003!
