So why is it that we can't or don't change just the tips?

 

i took my truck a few weeks ago to a shop and they said 1 or more injectors was returning to much fuel, i didnt let them test which injector it was i`m planning on replacing them all.

replacing the tip alone wouldnt fix returning to much fuel, that fuel metering part is above the nozzle.

 

Okay, so what about changing just the injector bodies if the tips are good? Has anyone done this and what were the results?
I have no fuel pressure at start up but the truck runs like a swiss watch after it starts.

 

That's if an injector sticks open, not when they wear out...if its not smoking or filling the crankcase with fuel, it should not hurt anything to drive. Mine did the same thing (started getting the longer starts) then an injector hung open...when they hang open, the truck knocks like a rod broke and you blacken entire interstate highways. Right before all this, I started getting a lope when the truck went into high idle...it was about a week later the injector hung open, right when I was just about home, from a cross country trip.

This time of year, every year since the common rails were introduced; there is multiple threads about cold no starts, but starts with ether or after being plugged in. In almost every case, it was injectors.

I had Formula 1 Diesel Flux Is tips installed when my injectors let go...then had issues with the solenoid on one of the (old) injectors...finally replaced all of them with new sticks with the Flux I tips. If I owned a common rail today, and had injector issues; I would call one of the shops and have their tips installed on new bodies.

Its the tips that are bad, not the bodies...the bodies contain the solenoid, the tips are what control the fuel flow and spray pattern.
