So today my TR3A starts to make a howling noise from the engine somewhere.
It sounds like someone blowing over the neck of a bottle, but more high
pitched. It sounds like it is coming from the left side of the engine, but I am
not sure. It is pretty loud and can be heard at idle but appears to diminish
with speed.
I am in the initial phases of troubleshooting. I fear that it might be a
spinning bearing or something. I'll run a stethoscope around to see if I can
find a general area.
Any suggestions on troubleshooting?
TIA,
Bill in Tehachapi
