I recently bought a used tractor and it smokes excessively. Droplets of oil actually come out of the exhaust and it runs down the pipe and burns on the muffles. It's a gas AC D17 III made in 1963. It starts smoking about 2 or 3 seconds after the engine starts running. I strongly suspect the valve seals are worn and letting oil into the cylinders.
So I removed the head. There was about 1/8 to 1/16 of an inch of oil in the cup of each piston.
I borrowed a valve removal tool, the kind that has two clamps that hold onto the bottom part of the spring and then you screw the top down to compress it.
The problem I'm encountering is the flat portion on top of the spring isn't moving down when when I compress it. The bottom of the spring just moves up. What am I doing wrong?
