fcoats · Dec 14, 2010

806 engine was running hot head gasket was blown. Had it repaired. have run it about 90 hours most hard some easy. Last ran it at low idle mostly digging holes for planting trees. oil has started comming out the exhaust. any ideas as to what could be causing this/

Thanks

Is it oil or condensation that his picked up exhaust soot? If the tractor has been running at an idle for quite awhile it may not be warming up properly. Especially with winter coming on.

Most likely the "oil" is not oil, but rather it is unburned diesel fuel. Pull the throttle wide open and make the ol' girl work for a while and see if it won't go away.

Not to worry! Most likely it's diesel "slobber" or "wet stacking". Very common when a diesel idles/ runs lightly loaded in colder weather.

The oily gunk in the exhaust is a mixture of unburned fuel and soot. Load the engine at working RPM's for 10 minutes or so - the slobber will disappear.

Yup exactly my 756 german is the worst slobbering tractor when used lightly. Nature of the beast
