I have a 1980 AC 5030 utility tractor. Japanese 2-cylinder diesel with about 1500 hours. Had it for 17 years and been a great little tractor for landscaping and mowing. I started it up yesterday and didn't notice that the throttle was set halfway (usually set at idle). Motor went immediately up to about 1500 rpm before I could grab the throttle lever down to idle. Everything seemed fine. Warmed it up until the temp gauge was in the run zone, then drove it on level ground for about 100 yards. All of a sudden it started puffing white smoke and looked like (and smelled like) engine oil drooling from the exhaust (was not coolant). First thought was -- that's all she wrote, this thing is done-for because new engine parts are mostly not available. I haven't looked in the oil or the coolant or done any pressure testing to find out what's causing the oil in the exhaust. I don't want to invest much money or time into it -- was ready to part with it anyhow. Question is ... if it's a cracked ring, how long will it last and is there anything I can do to keep it going? - thanks
