On my late 1951 8N, after draining the warm oil from the pan, letting drain well, when I go to remove the filter, the canister remains full and overflowing. To get the filter up and out takes a bit of force (and a good bit of oil spilled out) and the canister stays half full. Is this as it should be?
Also, when the engine is warm and idling, the oil pressure gauge never reads below 20 lbs. and pins the gauge above 50 lbs. when running at medium or higher speed. It has been this way for as long as I can remember – for decades.
Could these be related and indicate an oil blockage in a line? I really love the tractor and want it to be the best it can be. Any ideas on what to do to diagnose a problem and how to remedy it? Thanks so much for any help.
