I think the problem with old rope rear main seals and detergent oil is that it washes the accumulated sludge out causing it to leak. This is exascerbated by blowby in worn motors. I used to see the same thing with hot rodded diesel trucks. Even though they had a modern seal they would leak from blow by.
