Whining noise from outer space

[Sammy]

Hi there,

maybe someone can help me with this issue.

I own my 63 CdV for over 13 years now and sometimes - mostly in summer - 
when driving I hear a whining noise. 

Changed transmission fluid several times, rear bearings, front bearings, even changed the 
complete front brake system. No change. 

The sound is not depending on rpm of the motor, it's a mystery. 
And it doesn't appear every day, some months I hear nothing.

Did anyone had this problem before? 
I add an MP3 I recorded of this.

Thanks and stay healthy,
Sammy from Germany

I agree.  I'll bet a year's wages it's either PCV or intake gasket.  Those both cause intermittent whistling and both disappear (usually) when idling.

How do you want to send the money? :-)

I agree that it is not a typical bearing sound, but in my opinion it can't be 
the intake or anything related to the carb cause it's not related to rpm.

Driving in D : WHISTLING
Driving in N: WHISTLING (like idling)
Standing still idling: NO WHISTLING
Standing still with higher rpm: NO WHISTLING

Did you hear something about the governor making such noises like 
the shop manual says?

Right.  Intake manifold leaks and sticky PCV whistle has nothing to do with RPM.  My manifold gasket leak and sticky PCV whistling were not RPM related at all.  Whistling only happened while driving, almost never while in Park.  PS:  The intake manifold gaskets are not part of the carb.  They're between the manifold and the cylinder heads.  So if you're looking for leaks in the carb you may be missing it.  Good luck.

I don't recall you mentioning your carb. You mentioned that your mechanics are not used to american cars, and I wonder if the carb has been worked on or checked out.  Remember, the thin metal shim has to be under the carb, and the 1/4 inch thick vacuum spacer between the metal shim and manifold.  Check the spacer for cracks, which they famously get around the inlet tube.  You can't fix those items with permatex or other sealants, the pressure gets too great with heat from the manifold.  Review carb and spacer replacement in your manual to make sure you have them in the right place.  i think Lee has a good point.  Even though you are probably frustrated, repeat your elimination testing until you find it.  Yes, I do the same thing myself!!

I'll give it a try ... :-)
