On this site I have read that some have put extra oil in trans to keep the power steering and brakes working. With the oil level raised then the MVC pump will not draw in air. My question is, were does the vacuum leak occur? The 856 I am working on has no pressure at all. I can remove the pressure sender and leave the hole open and run the tractor at full throttle and not a drop of oil will come out. I have removed the MCV and then when I took the cover off of the filter on the other side of trans I noticed oil then ran out of the port for the MCV sump. The hydraulic filter is old and will be changed. Do both pumps draw through this filter? If the filter is bad, could the larger pump cause a vacuum in the line to the MCV pump? Plastic sump check valve and spring were in place. Thanks,Denny

To top that off, you have a cup with oil in it ("why would you want to lubricate your carburetor?"). On closer examination (and some reading in a AC D-14 service manual), I found out that this is a pretty ingenious method of cleaning the air in the tractor's intake tract.
