<VV> Unknown screech noise in/on engine
Message-ID: <000501c5db21$8e206aa0$6500a8c0@athlon900>

After 37 years dealing with vairs, I found a new (to me) noise. Just
after changing spark plugs (Autolite 425) the engine began to make a
constant screeching noise, like moving a metalic cap (like old fashion soft
drinks) on a flat glass. The noise is constant with the engine ruuning. The
pitch is really high. Took off the belt for isolating alternator, belt
tensioner and fan bearings with no change. The noise pitch is different from
dry rocker arms, dry valve stems or a loose bellhousing bolt against the
flywheel.
Think that changing plugs had nothing to do and was just coincidental.
Engine is a 110 with less than 2,000 miles, no oil comsuption, no oil smoke.

Would somebody point me on what can cause this noise ?.... thanks in
advance for any help.

Dan , Did a tool or an old plug fall down behind the harmonic balencer ?

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
vacuum.
Thanks anyway

Daniel,

That's great that you found the source of the noise and it wasn't serious. I
was going to suggest that the problem could be due to putting FORD spark
plugs in a CHEVY :^)

Maybe it's a dry bushing in the distributor...
