..:: The waterfall noise situation ::..

Hello Roverers...
For a very long time I've experienced the "noisy waterfall" issue. I've bled my system just as the RAVE suggests, so it goes away and comes back days later.
Lately I've spent near an hour onna Saturday morning carefully bleeding it as instructed, letting all coolant drain, refill, drain, and then place everything back and off I go.
No visible coolant leaks, levels seem to hold, haven't topped-it off since last bleed.
But these past days the waterfall noise is pretty much, usually in third gear is most noticeable when revving up; yesterday did it without even moving and revving up, plus a high pitch noise, all goes away once I depressed the pedal.
Sometimes I think the waterfall noise is coming out of the gearbox rather than from behind the dash, I will just have to hear closer to rule one or the other.
Radiator does have the upper little plastic tubing where you attach the return hose broken off, so I had to JB-Weld it pretty good, although you can see it moist, I don't see a leak from it. Yes some should be sifting out through the cracks, but does not leak.
Any feedback regarding the predicament I'm in will be very much appreciated, thanks! ;-]#

If the noise goes away when the clutch pedal is depressed, then it's not the cooling system.
Possibly a throw out bearing?

All signs point to your cooling system, man. The JB Weld might be a little leaky dude. Any air sucked in while the motor cools will end up in your heater core. Button that bad boy up and your waterfall will be gone forever or until another part of the crappy cooling system decides to **** the bed.

Aw man, you got the sickness alright. Your truck has gotten in your head! I get tht way sometimes with mine; do simple service and fix problem, problem reappears, redo simple service, problem reappears, convince myself that reappearing problem that was temporarily fixed by simple service HAS TO BE SOMETHING ELSE!!!

The truth is...
You have a leak in your cooling system. After running the vehicle the system pressurizes. When you shut it down the reduction in pressure creates a vacumm pulling in air. Hence the repetitive bleading.
Buy a pressure tester, pressurize the system to 16 lbs and start looking for leaks. If it doesnt lose pressure, im wrong.

Clutch pedal? Adolfo, which pedal are you pushing to make the noise go away. Most of us don't have a clutch pedal.
Password could be right with that if you have a manual tranny, but if not I agree your leak may not be leaking much but it could be sucking air in. which does suck.

As per the system being sucking air instead of leaking coolant, it all seems to point towards that. Again, I guess it's time to replace that old radiator.
Thanks! ;-]#
