not sure what your question is, but the weep holes were designed to alert the operator of the tractor that your engine is going to need work fairly soon, now depending on the degree of electrolysis on your sleeves you could get away with anywhere from 1 month to maybe even 5 years, again all that the weeps mean is a warning and if your adding that much antifreeze a week then your time is probably on the short side of 5 years.

your engine block has 3 grooves in the lower counterbores the top & bottom grooves have o-rings in them while the middle one usaully is left empty, so when the top o-ring has become eroded enough to let fluid pass by then the lower one still holds the fluid out of the crankcase, while allowing it to escape through the weep holes. myself when i rebiuld jd motors usaully will install an extra o-ring in that middle groove, just a little extra longevity on that area of the motor
