Hello i am new here and new tractor owner I just purchased my first mf135 6spd with perkins diesel i believe its a 68 or 69 model. The tractor runs fine but i noticed an oil leak coming in front of the weep hole theres not much coming from the weep hole as the cotter pin is free. the square plate behind the weep hole is a little damp but that gasket is shot. Is this a rear main seal or rear oil pan gasket that is causing the leak?
