 Help! Blown head gasket?

I have an L2850 with unknown hours. The other day it started smoking like a son-of-a-gun. I looked at the oil and it's milky. Blown head gasket automatically comes to mind but could it be anything else. Also it's become a little hard to start, but it is colder these days. Any comments or suggestions. Also, what am I looking at to fix it?

Could be, but you could have a cracked block. Have you over heated i?

 Help! Blown head gasket?

It is possible it has overheated. There is a nasty oil leak in the engine and I'm religious at topping the oil every time I use it. I has never overheated on me but I can't speak for the original owner. I can't speak to the original owner either as I bought the tractor from his widow. How can I differentiate between gasket or block?

First look in the radiator and top it off with water only if you are sure it is a radiator leak. Do change the oil out to fresh so not to hurt your rotating parts. Head gaskets or upper cylinder leaks will show up with little bubbles in the radiator when you remove the cap with the engine running or if you have a pressure tester it will show the pressure there.

Art,
Thanks for the suggestions. I have not tried them yet. If I had diesel fuel in the crank case, would the oil seem milky? Would I smell it?

The reason I ask is, before I noticed the milky oil I had a hard time starting the tractor. I attributed this to the cold. I had to turn the engine over quite a bit before it would stay running. That is when the excessive smoking started. Could I have driven fuel down into the crank case?

Obviously I'm grasping for a cheaper problem than a cracked block! - Brian

Most all oils I've seen turn milky with oil. With fuel oil they might get thicker if it is partially burnt or normally thinner if raw but not milky. By the way, you should only need to have the engine at an idle for the bubble test.

The water in the oil forms an reverse emmulsion. Milk is a normal emmulsion, oil in water. The high surfactants in the diesel oil normally form a white emmulsion.
The diesel will not give you an emmulsion.
