Oliver 1850

Jkittle · Jun 25, 2014

I have an Oliver 1850 with a Perkins Diesel engine that we were using this last weekend at a show to pull the people shuttle. So basically the engine had little to no load at all and running low rpms. When I noticed some oil up on the muffler rain cap and them some splatters on the hood. I first thought it was moisture but 30 minutes later someone stopped me and said that there is oil on the side of the engine block. It appears that all of the oil is coming out of the exhaust manifold. I did shut the tractor down and there was still oils showing up on the dipstick and the engine still had good oil pressure. Does anyone have an idea what the problem is before I pull the head and look inside. Would it be a valve guide seal or maybe a broken oil ring?
Thank you in advance for your assistance in this matter.

Welcome to the world of "diesel slobber". It is not working hard enough to make the heat it needs to burn clean. Does it have a working thermostat to keep the temp up, if not that would help. Any diesel engine can do this as the idle no load or light load exhaust temp is much cooler than a gas engine. Work it and I bet it will stop dripping and be fine. I've seen newly rebuilt engines drip too, put under a load and it will stop.

Both of the 1850s we had did the same thing when they were not worked hard. Its just the nature of the beast and there is nothing wrong with it, It just needs to be worked and the slobber will go away. Bandit

i agree it sounds like diesel slobber to me also. when the tractor isn't working hard it doesn't clean the head our well. this is notorious for the gm olivers, our super 99 was all black by the manifold once because it wasn't working hard.
