(Home) Noise. Leak found

it was the heater valve assembly (so not major - breaths sigh of relief) - at the front near the upward facing fan


and the screeching noise - revved the motor up to let the mechanic take a look from underneath and loads of debris kicked out of the fan area and the noise stopped - must have been a stone of something loaded somewhere and was being worn away - anyway noise now gone - (#2699) skippy, 9 Apr 02
