Tractor starts and runs perfect. Has been real clean up 'til a few days ago. Tractor has set around idle for much of last 2 years. Couple days ago it started blue smoke, not real heavy but steady and at all rpm. Took down road to get warmed up and wide open in road gear. Still no change. Today started it up to move some other tractors and ran perfectly clean . Moved it to another area and let it set running at around 700 rpm or so. Ran clean for 10 min. Looked over after that and smoke again but cleared up after another 5 min. Just seems to be hit& miss whether it blue smokes. Vent tube is open. New 15-40 Rotella oil. Also did this before oil change but seems to be worse now. Do I need to just put this on a plow and work the crap out of it? Do oil rings set up from non use? Chevy v-8,s used to do this back in the '70,s when the "too small" oil drain back holes in heads would plug up from either gunk or deteriorated valve umbrella seals and would do this same thing. Just wondering if there,s something I'm missing here.
