This is the biggest misconception of a diesel engine. ETHER does not make it worn out engine. YOu just prolonging and not fixing the problem. What is your oil pressure hold? 45-60lbs? How much crank pressure do you have or blow by. There will be more when warmed up, even on a fresh motor. I rebuild dozen of IH engines a year. I just purchased a 706 with 12,000 hours on it. It needed ether to start.
However the engine was not worn out. It has good compression and 60 lbs of oil pressure. It has minimal blow by. The culprit was a weak injection pump. If your head on the pump is worn out you will never create enough pressure to properly atomize the fuel when they pump is turning slow at cranking speeding of the starter. I also ground the valves and created 40lbs more compression. Now it runs perfect and starts perfect.
Just to call and engine worn out hard starting is short sighted. I've been a mechanic my whole life and have my college degree from wyotech. I have to deal with hard starting international everyday and fix them. You need to Diagnose the problem not throw parts at it. Compression, oil pressure, Blowby pressure, and fuel pressure; Then rebuild.
