Hello all, This is my first diesel and I’ve been through it and learned a ton but still new and need some help. 7.3 idi
I recently had an injector knock that went away after soaking the injectors in Lucas injector cleaner, so I took the beast on a road trip when the knock came back as well as low power and black smoke under load, so I ordered new injectors and headed home (400miles away). Rookie mistake I know now. About 80 miles from home I began smelling unburnt diesel and then 20 miles from home it gained a low growl noise from the engine that almost sounds hollow, and is much louder under load.
Fast forward to today when I got the new injectors in. She fired up right away and sounds pretty good at idle but that hollow growl is definitely there under load. Especially taking off in second, which normally is no problem.
My theory is a washed out/scored cylinder and I’ve lost compression l but what do I know. Would that cause the hollow sound? Besides sounding bad it drives pretty well. Much better than before the new injectors anyway.
Where do I go from here? Thoughts on what I did to it?
Help me fix the beast! Thanks y’all
