Hobo,
Thanks for the reply. I have Googled, the cylinder leak test and have a couple of questions. Forgive me if these questions seem simple or elementary, this is the first time I have really tired to diagnosis such an issue. I understand the cylinder leak test requires you to pressurize the cylinder at TDC with compressed air and see how much and where the cylinder is leaking air at, be it the intake, exhaust, rings, or head gasket, etc. What I am struggling to make the connection with is for in this case when the compression test showed all cylinders were within spec, what new information will this test provide me in regards to the reason that the engine is followed by a large cloud of blue smoke? Can the compression rings be sealing allowing for good compression results but the oil rings not sealing and allowing the oil into the cylinders, thus the blue cloud of smoke? But if this is the case, how would the blue smoke be coming out of the oil filler tube as well as the exhaust?

Although he himself has never actually owned or restored a tractor, he was always enthusiastic and always around helping with other peoples projects.
