Bolens G152/Iseki Tx1500 smoking

[DavidS]

after I run my tractor for about 45 minutes to an hour it starts putting off a blue colored smoke from the exhaust. I am pretty sure it is not oil smoke for 2 reasons, 1. does not smell like oils smoke. 2. I never have to add any oil. Any ideas on what this smoke could be from and how (if any way) to fix it?

See my reply under owning operating, you may have diesel fuel leaking past worn rings. It can vary depending on how hard you work the engine. Don
