I have a leak from the weep hole at the bell housing plate on my JD M. It depends on engine speed, but at high idle it is about a drop every 10-15 seconds. It will continue to leak some after it is shut off, and leaves a spot on the floor but eventually stops. Is there any way that this type of leak could be caused by the oil pan gasket? I have already replaced the rear main seal, and that did not resolve the issue. I would think if it was the oil pan gasket, it would leak continuously until the oil level fell far enough and then stop. Is the oil pan pressurized during running conditions? Thanks.
