Maybe someone can help?
I have a Ford C6 on the back of a 351C in a 1973 Iso Fidia (big Italian Sedan 1968-74).
After its first drive in months (less than a mile) I noticed for the first time a rumbling/whining noise when stationary in park, reverse, and neutral. It was noisiest in reverse, but quiet in any of the forward gear positions.
First thing I did was check the oil level, and found no indication on the dipstick, so I topped it up, but the noise is still there.
Is there an easy cure, or does it sound like a rebuild? Any ideas, anyone?
