      I found it !  It was not tipical Corvair noise. Actually it was 
related to the plugs change on the Rampside. It has a custom air compressor 
which has a control hose attached to a bronze tee. While moving around, for 
plugs changing, I dissconnected, accidentaly, the small plastic hose on the 
bronze tee which, in turn produced that screeching noise with the engine 
      Thanks anyway
