[Gold Digger]

Back to the holes in the dipper trays, 50 something years ago I tour down a 29 engine with 1 inch holes in it that looked like factory made holes. I asked an old man that had lots of model A experience back in the day and he said that the Gleaner combine engines started using trays with holes in them and the larger oil vent pipe for a longer lasting engine. He said that the hot rodders back then started doing the same thing. It was claimed that it let oil down to the bottom of the pan quicker.
