Ned, When I overhauled my 79, I knocked out the balls to make sure the engine was clean throughout. One end of the oil galleries has threaded plugs and the other end has interference fit steel balls. I think there were 3 total. I used a long piece of 1/2 inch round stock to do the job. The balls are not something you want to forget as they plug the end of the engine in the bell housing area.

Re: [MBZ] Steel ball of main oil gallery
Ned - I don't have a 124 manual to check out, but generally the steel ball is used to plug an oil passage after it is drilled. You can't always machine a dead end hole, so they drill all the way through and then plug the openings that should end up closed. When you are trying to clean out any accumulated debis, you want to open the passages back up for access to get proper cleaning and verification of cleanliness by inspection performed by looking through the hole and/or blowing air through it.

I believe it provides a means to rod out and clean oil passages. I don't think its done unless the block is out of the car.
