Hey gang.. Does any one know the life or approximate hour time a kubota diesel will last? I realize this is a wild question, however given nomal care and no hour meter on this old unit, I was wondering. I am not that familar with the longevity of these little three cyl. engines or there ability to run year after year with hard work.this unit I just got needs a valve job and I have the head in the shop now. just would like to know how the rings hold up after a valve job or it they start sucking oil as with a gasser. Probaly better to go ahead and major it but I do not have the lifetime maintenance of it ,,, But I do know it has some long hard time on it, and some very rough ones all so. guess I know the answer but always like to hear other opinions. thanks.
