Man, that tractor looks like it had leaky valve stem and or piston ring issues.
Along with the snake issues.
That tractor had a broken pre-combustion chamber that rattled around the cylinder bore for god knows how long, but amazingly didnt wreck the piston.
Most of the rings where actually broken and jammed into the piston grooves
It blew more smoke out the engine breather than the exhuast.
It used more oil than diesel
It used large quantities of " Start you Bastard"....actually...in the end I had a spray bottle with thinners in it as it worked out cheaper...
It would boil itself dry and completely seize up, but next day it was good to go..
When I pulled the motor down the crank shaft was in amazingly good condition for a 50yr old tractor. Only needed a .010' & .020" grind undersize. It had never been ground.
Was great old tractor, and old International B414, a true wonder of British engineering. You just could not kill it.
All up it cost $700 for a crank grind, new pistons,liners & seals
