Ok. I have been looking around and im hoping this issue isn't worst case scenerio. My 1700 BD has always blown a little WHITE smoke. Always seemed to blow more while in high range. Hauling some dirt up hill with the pond scoop today it seemed worse than ever. Looked like an old steam locomotive comming up the hill. had it in second gear high range. So i dropped down to fifth in low gear then in third low range. Same thing. In the past if i would shift in to low range the smoke would clear a little and not be quite as bad or if i put the brush hog on under load the smoke would clear. Not today. At times it appeared to be puffing., IE the smoke would not blow as bad and then it would get thicker then taper off and again get thicker. When I shut down durring a break and started up later there was little to no smoke at start up. When it warmed up it would start again. Doesn't appeare to have any power loss. If so it's nominal. No over heating. Fresh diesel. No blow by at the dip stick or coolant. White smoke from the breather tube but no sign of oil drip. I guess it would be oil slobber (small trickle) run down the exhaust. It is an old, i guess, origional exhaust. Sounds normal. Used to leak at the fuel bowel but thats fixed. No apparant leaks around injectors. Could use some help. Dealer wasn't much on help in past.
