Has the oil been changed and what has it been doing the last few months ,chores and piddling around can cause a moisture build up and the vent pump makes this look bad. I would work the tractor and see what oil consumption is . You can take the tappet cover off and learn a lot .   [Reply]  [No Email]

New pistons and liners, a fresh head, and that tractor will give you many years of good service.   [Reply]  [No Email]

New pistons & liners is the only cure for blow-by. If only the steering quits then I think control valve under steering wheel would be the problem.   [Reply]  [No Email]

With new valve seating surfaces, the combustion pressures rise and do as you said. Years ago dad had a '66 Chev V8 and it needed a valve job. Got the valve job and lo and behold then it needed rings. I assumed that the guy that did the work left some lapping compound on the seats, but later learned what I just said. Mark   [Reply]  [No Email]
