We drove the '66 Ghia to Josee's parents in Montreal (3.5hrs at 65-70MPH) no problem on Saturday. Yesterday driving home close to Quebec there was a high pitch whine, like a fan following the engine revs. At first I thought it was too hot. (I don't have a temp guage) So I stopped on the side, saw that the fan belt was still there and the engine was still on and the sound went away..... drove some more and it came back a little quieter and we drove home. After that, last night back to normal...

Oil needs a change but was full. It wasn't too hot out maybe 70F in Montreal and 65F in Quebec (too cool for normal but at least the sun was out)

Question: If the car is showing signs of getting too HOT, would it whine like a supercharger was in there??? I though maybe the generator brushes but they seem fine as well.......

My immediate guess is a leaf or piece of plastic stuck in the inlet side of the fan, too big to fit between the blades and too stuck to fall out after you shut the car off.
Do a sweep with your hand, just to be sure it's gone. Most mechanical stuff that would make a noise would make an irregular noise if it was out-of-round or dry of lube; a cheeeepcheeeepcheeep kind of thing, not a steady pitch.
Good luck!
I will check. But when the car cooled down it was OK.........

Could this be an issue???? I looked at the + lead to the battery and I could move by hand....Question: Possible the + lead found a dead spot and since we were blasting the radio, light on ALL THE TIME, that the generator was outputting too much....since the battery wasn't (maybe) supplying any of the power needed?

The whine sounded pretty damn cool though, like a supercharger kicking in.... WWhhhhhhvvveeeeeeeeeeeee........

Now it's quiet!

You have a radio. I do not have a radio; for me the problem would be a whistle caused by the car's mechanical components or by a high volume of air being forced through a small or unduly restrictive opening -- but maybe your noise is electronic in nature ...
Hmmm.
Are you saying that the problem is absolutely coming from the car, or could it be from the electronics?
Is there a filter between the radio and the alternator? They used to call them pre-amp filters. It took the whine of an old generator or alternator and modulated it somehow, so it wouldn't be audible through the speakers.
Maybe you have one?
My money's still on something being wrong with the fan.

This thing, below, had a similar problem, but it was from the fan itself being misaligned. I cared so little for that engine that I didn't even part it out. Warren Miles got it, intact and free of charge, and probably wound up resurrecting it somehow.

Could be debree has got sucked into the fan from the intake side. cut her off and check for leaves or a twig. I have even had a mouse in one.. SORRY MICKEY!

It could also be a bad bearing. If you have twin carbs it's not to hard to pull and fix. .

I'm hoping for your sake, it's just debre.
It was a noise not from the radio at all. It was motor whine, quite loud not a screech. It's gone now but happened in the 3rd hour of the drive while stuck at road construction. It was revving with the motor.

I stopped on the side of the road (motor still on) and by the time I went to the back it was gone. Continued and in 5 minutes came back although a lot lighter. Drove home....let it cool.....went for a drive and the sounds not there.

I will check all your recommendations but wonder if a motor is getting close to getting too HOT, would this make it sound different?

The sound was a nice mechanical, revving whine..... figures now it's gone........

I think I am going to install a temp gauge.

Mike:

Sounds like you sucked something in to the Fan and it got caught somewhere, causing the whine. Not altogether uncommon. Sometimes whatever it is dislodges when the revs change and it moves position and goes away.

Drive it. If it returns, then try to figure out what it is. Unless it's a dry-bearing squeal (generator/alternator thrust bearing which, BTW, doesn't change pitch much) then it's probably not much to worry about. As a precaution, "borrow" one of Josee's mirrors and look around the fan inlet. If you don't see anything obvious, just keep driving it......

My first thought was a slipping fan belt.

Later Mike said, "Could this be an issue???? I looked at the + lead to the battery and I could move by hand....". I am assuming you mean the wires were still tight but the terminal itself was slightly loose on the alternator?

The last time I had an alternator that I could move the + lead by hand, I very nearly burned down the car! It turns out the electrical connection had failed internally, providing a direct path from Battery + lead to ground. Lots of smoke. Lot's of heat. Lots of adrenelen removing the battery cable. Another few seconds and it might have been all gone. Hope this is NOT your case.
Nope.....thank god! It was just a high pitched whine like those rice burner Hondas with superchargers installed. I had all the power. I actually thought it sounded cool.

It's gone now (the sound) [This is the 66 Ghia]
Solex Pict30/32 single carb!

Tomorrow I will do a check for anything sucked in. I will compression check, change the oil and do a carb adjust.

The only OTHER thing we did (and we do this to our daily drivers) is I filled up from Josee's dad fuel on the farm. Whenever we visit he tells us to fill up before we go. The new daily drivers all have electronic do-dads.... wonder if Kangaroo gas could have done this...

But the main thing is that the sound appeared about 3 hours into the drive back and now it's gone.

Today was a day of taking the front bumper off my Jag to take the headlight assembly out &^%$#!....it's BEER time right now. Karmann the Ghia gets a look over tomorrow.

I am leaning towards a loose or cracked Positive battery lead. I think that was the problem. The lead (today) I looked at it. (Had an appointment with my knee surgeon) and at the hospital the car wouldn't start. I looked at the battery again and noticed the + terminal could need some tightening. When I wrenched it a bit, it broke. This lead end is only 2 years old. (Made in China??????)

I installed a new one $2.25

So I think the COOL sound was the generator overheating because the + lead was or found a flat spot and the GEN was doing all the work.

Note: The Ghia, when you turn the key the lights go on, so lights on, I like tunes........ too much for an electrical system that depends on a GEN because of a battery connection.
