The heater system on the 82 is different than any other water cooled Vanagon. The heater valve placement and hose routing is different along with the flap controls. They do seem to make noises not often heard on other years. Raising the front helps bleed the radiator but actually makes it harder to get the air out of the heater as there is no bleed valve and the heater core is then the high point. To get the air out of the heater, drive around with the heat lever all of the way to the right (max). Do this even with the engine cold as you are trying to push the bubbles back to the rear and when the engine is cold this will be the only path available for the water pump to pump the coolant( unless the thermostat is bad). Drive down a steep hill with the engine at a high rpm with the heater valve open all the way and leave it open until the noises diminish. It may take a few days.
