955L leaking fuel from exhaust

Danv · Aug 10, 2017

I have a 955l 13x track loader. Recently it has developed a large fuel leak. The machine lost power, sounded like there was an exhaust leak and was pouring fuel from what looks like the exhaust just past the turbo.

I had nice lately it was getting harder to shut the engine down, it also has be starting to smoke white more and more. The oil level does not change. I replaced the number 2 injector and line because it was leaking from around the injector body.

Any ideas why so much fuel would be in the exhaust?

If a tip has blown off an injector or injectors, it is pumping un atomized raw fuel in to a cylinder which won't burn properly and
is basically sitting on top of a piston and pumped out the exhaust. This would also explain the white smoking and hard to shut
down because there is enough raw fuel in a cylinder/cylinders to keep running even if the fuel is shut off. I would guess it is
seriously down on power also

I ordered everthing to replace the lines and injectors, so we will see where that gets me.
