Can't tell from the photo. But how much of the injector tip is left?
The used one I have sitting here without the copper washer is 16.5mm
I am not sure what year that is from. It's an oid core.


M-chan is right that it's time for a borescope. Your going to need one with
a camera that will fit into the injector hole is 7.1mm or the glow plug at 8.1mm.
Even my new to me Snap-On BK6000 is 8.65mm. So it won't even fit.
But I did take the measurements on an injector and plug I have sitting here.
The bigger cameras you can get at the local home store will never fit.
They would be good for checking the cup to see if you got it clean and
ready to install but that is about all.

You might look at a solid tube with a mirror and lens type borescope.

Probably was a REMAN (remanufactured) not a KEMAN. It appears the injector failed to close, causing an over fuelling issue which in turn melts the tip of the injector off.

 

Which can then cause this...






And one more...

 

That's a fine example of torching.

 

Yahiko is right there are few bore scopes that will fit in a 6.0; injector hole or glow plug.
It has to be 8mm flat no bigger.
I do not remember which year it was but Snap-on did make one at one time that would fit. I borroed one from a friend and it fit no problem.

 

I know that Snap-On does make a small probe for mine this I
think is 5.5mm The think is I already have 2 probes and $300~$400
more for one probe that I won't use that much won't be happening soon.
But you can get them.

My wife got me one for Christmas a couple of years ago, it's an AC Delco, and it has a 5/16th end. When my engine blew up, I ran it down into the #3 injector hole (the one in the pictures) and I couldn't see anything wrong. So it either has a poor light, or I'm too old to see.

 

I shot this video with my BK6000 back in July

That was the oil cooler and you can see how well that showed things.
With the smaller probe I bet your still going to get a good image
from a Snap-On camera.
