I have a 1957 D14 that has oil flowing out of the power steering breather just in front of the radiator when the tractor is put under a load and throttle is nearly wide open. Any other time there is no such problem. I checked the oil in the power steering sump. The sump is 2.25 inches deep and there is 1 inch of oil in it. I assume half-full. What is causing this problem? The tractor runs very well otherwise. There are repairs that need to be made. I have already replaced some parts, others coming. Just replaced the rear rims and tires because of rust. My mechanical skills are limited. I grew up on an Allis Chalmers WC, a John Deere 45 and a John Deere 630. During the summer working at my uncle's farm, drove a D14. Your insights on my problem are greatly appreciated. Dick
