Hey guys, it's probably a common problem but I cannot find the proper Information for my specific case. John deere 160clc I had a leaking injector that I replaced and it worked Allright for about 5h. Then the excavator started blowing white smoke and didn't want to start. I realized the new Injector was spurting a lot of air and I can't never bleed it, always a bunch of air. I can't start the excavator just fine if I unscrew this specific injector so that the air can get out. (Only works with this one). Then I can rescrew it, but the excavator runs rough with smoke(white, maybe blueish). I don't see what else could have broken other than the new injector. I want to switch its place with another one to test of its the line or the injector, but I'm waiting to get the job done in case I break a seal doing so. Meanwhile i'm reaching out to you to see if you already encountered something like this. Am I on the right track ? Regards JP
It’s very possible that the injector is stuck open and your getting compression blowing back up thru the injector.. Another problem is with that inj pump.. The “DE” pump has a broken spring problem.. & it produces a bunch of air, BUT it won’t be just 1 cylinder.. Have u loosened ALL the lines AT THE INJECTORS and had someone crank the engine to see if it’s just on 1 cyl or ALL of them.?? If indeed it’s only on 1 cyl, it’s probably just that 1 injector.. Good luck
@thepumthanks, yes i tried the injectors when someone crank but also as the excavator was running. Only this injector shoot more air then fuel. The rest a clean fuel. Thanks for taking the time I'm glad to see I'm on the right path.
