White Smoke

[willhoff]

I have a JD diesel engine that blows white smoke going down a hill. When I start back up the hill it clears up and runs fine. The engine does not use any oil. What should I look for??

water in the fuel tank...

Either that, or you're the Pope.

I always attributed white smoke to unburned fuel to start with. It can be other things but unburned fuel is most common I think. You will see it when cranking before it starts. If you had white smoke all the time and it was hard to start I would suspect a compression problem But just down hill I don't know weather that is a worry or not.

Is the coolant level steady?

Truly brilliant.

That was one of my thoughts.. I drained the fuel filter several times >> that didn't help? I put a new filter on the tractor >> that didn't help? I did not see any water in the fuel when I opened the drain.

I never see any smoke when this tractor starts. Just touch the key and it is running! This morning when I was feeding cows, I could hear a little miss. I was starting to question the injectors?

I'm not loosing any coolant.

Its probably the tank. Water settled into a corner or some BS like that. Diesel is a light oil so water sinks to the bottom and usually pools. Even a dime sized drop can give you fits.

Best thing is to remove the tank if possible, dump and clean it, reinstall. Draining is not usually enough. You could also vacuum it.

ps.... its good to be the pope.

Here is some interesting stuff to read about smoke. They are trying to seel a product but the smoke causes are valid.

Colour of engine smoke and when it occurs tells about internal condition

Now that's thinking...!

try parking on a down hill slope and let the tractor sit...then check the fuel supply chain starting at the tank...

What JD is it?
Many are made by others.
First check the valve clearance. Then pull the injectors and reattach them outside the engine and spin the engine at full throttle. this is not to start the tractor but to see the injector spray pattern. third what type of air filtering system does it have? Clean the oil bath or replace the paper filter if it is dirty.

 

[rdbigfarmboy]

Depending on the actual manufacturer I would probably remove the injectors and fill the cylinders with DOT 4 brake fluid acetone and ATF and check and refill daily until the fluid easliy and quickly drains past the rings. Plan on thisbeing a 2 week task and use several quarts of brake fluid and atf. This is to remove any deposits from the rings before they stick or break.
First check valves then injectors then air supply and last decarbon the rings

That's very good news for you!

 

[willhoff]

I will pull the tank and empty it. That sounds allot easier then pulling the head. Thank You..
