180 Diesel spewing oil

But, yesterday hooked up the bushhog to finish clearing what I started last fall and as soon as I brought it up to speed the exhaust started showing signs of oil. Bad enough it was running out of the manifold and down the block. Not a steady stream but enough to really make it smoke. Oil level is still ok, This was the first time this year I have put any load on it, still runs great but am curious. Any ideas?

Thanks for the help.

As Oliver stated above, when I was in the military, we had tanks and APC that would sit and idle for hours. They would suffer from "wet stacking." It is usually worse when a diesel sits and idles for a long time in cold weather, particularly if the engine has not been run at high enough rpm to get the engine hot. It really comes from incomplete combustion of the fuel. The unburned fuel collects in the exhaust stack or exhaust pipe.

About the only solution is to set the throttle at about 1/3 if you are going to be idle for an extended period. It burns a little more fuel, but the unburned fuel won't collet in the exhaust or run past the rings and dilute your oil.

Good Luck.
