Need some help! While mowing hay with my 1850 gas, the tractor all of a sudden bogged down and white smoke started coming out the vent at the back of the valve cover. There was no knocks or noices coming from the engine. Stopped tractor and checked oil (was good when started) down several quarts. white smoke coming out of dip stick. Left sit for an hour, went back to change tractors, the 1850 started right up and after about 10 min. the smoke started coming out. What's up.

1850, 1855 gas engines were Oliver, and they had wet-type sleeves

When you have white smoke or excessive white vapor coming out of crankcase vent or oil filler cap you have excessive blowby which means there is excessive compression leaking past the rings for one reason or another. Antifreeze in the oil don't do this but will smoke white if it's leaking into the compression area of the cylinder.

Thanks for all the help! We took the filters off and found metal shavings. We are pretty sure that the old girl spun a bearing. I think the cost is going to be too much to fix her. But there is still no knocks or engine noice and she starts right up. I found a 1750 gas near by going to go look at her. Thanks again everyone!

Hmmmmm, I am in Harrisonburg, Va in the mountains. It may be a little far to truck a 10,000 pound tractor. e-mail me if you are interested and I can find out the price for you. BTW what are you going to with your old tractor??? are you parting it out or selling it or what???

I believe the 1850 has a perkins, like my White. If so, then other causes of antifreeze getting into the combustion chamber that have been mentioned are not likely e.g. the Perkins has dry sleeves so you can eliminate leakage around sleeve O-ring seals, also a cracked block since i have never heard of a block cracking thru a sleeve into the combustion chamber. A head gasket is more likely. At least it is the easiest thing to check right off.
Good luck on that

If the smoke is caused from antifreeze then the water level will certainly drop in the cooling system. Check the water level first. The smoke will have a "sweet" smell to it also. There should also be white smoke from the exhaust pipe if the water is entering at or above the head gasket.

If the water is entering the crank case below the gasket surface then the oil level will rise as the water fills the oil pan. Either way, the head will have to come off.

If you are lucky the head gasket gave it up. Your second best hope is the O-rings at the bottom of the sleeves have started leaking. Other than those 2 cases, you are going to have to spend some serious money.

Perhaps you melted a piston. That will cause a tremendous oil loss, white smoke and a sudden loss of power. But the white smoke will not have the sweet smell like antifreeze.

Let us know what has happened.

Sounds like you have a cracked crankcase or faulty head gasket

White Smoke is almost always antifreeze.In your case it is leaking from the waterjacket into the crankcase. If you are lucky it will be the head gasket. On my dads marine motor, not so lucky,cracked block. Can also be cracked head. Oil consumption skyrockets because antifreeze is getting on cylinder walls below the pistons and smoking off. The oil mixed with the antifreeze globs up and vaporizes,hence white smoke from engine vents. A really bad leak causes the oil to form "snot", a grayish oil with droplets in it.
