Okay, this is on my '66 Buick Sportwagon.
I got the motor running yesterday, and noticed a few strange "clicking/clacking" noises...
One sounds like lifters...
The second was a bit different, and definitely sounds like its coming from the rear of the engine... My neighbor confirmed that it sounds like its at the back...
Then I found the noise goes away when I hold the brake pedal down... There's nothing connected except a vacuum hose...
Then while we were listening to it, I realized that the noise was cyclical... I could hear the noise "clacking" every 1/2 second or so for 2-3 seconds, followed by an audible "click", followed by silence for 1 second, then another "click", followed by the clacking... And it seemed pretty regular...
Trying to figure what would make such a cyclical noise from the bell housing area, and then I realized the voltage regulator is mounted on the firewall right above the area...
I didn't get a chance to investigate further...
I also had the battery charger hooked up WHILE the car was running... Wonder if that "helped" make that noise audible...
