4420 diesel with white smoke

farmeroz · Dec 20, 2013

Bad case of white smoke, loss of power and hard starting. A bit new to diesels so a little help to identify the cause would be appreciated. This is a new to me combine. It has a new air cleaner in it.

Sounds like fuel filter to me, my 4400 did that when the screen in the bottom of the tank plugged up.

With engine running place your hand in the exhaust. If your hand tastes sweet then you have a head/gasket or some other problem with the cooling system entering the combustion chamber. Is the crankcase oil MILKY? With engine running disconnect each fuel line (one at a time) and check to see if white smoke stops.

Well that filter in the glass bowl was almost completely blocked. I cleaned it and ran the combine, did help but still some white smoke. I didn't have an extra filter for up on the engine so maybe tomorrow I can run for another one. After that I have to try some of John Deere D's suggestions.
