Top is the return line that hooks to each injector. You can see the seal in the picture, thats what is a major cause of fuel in the oil leak.. THIS MUST be replaced when ever its removed.
Top right is injector cups just before install, they have loc-tite which is what seals them to the head applied
Below is injector cups cleaned and ready for install
Eric,
Neat !! In the picture with the injector cup that have Loc-tite, is that an injector laying on its side? Also, when replacing an injector, you don't replace the injector cup do you?
We have been talking about these things failing, its good to see some actual pictures! The shop manual I have only has drawings, no pictures. Kind of odd.

Yes, its from the crap that builds up on the feed line, its falls down there when you remove it, its not there when engine is assembled as some believe. You put it there when you take it apart

kad, the crud is above the fitting and not in there, it is inbetween the nut and the ouside of the fitting, falls in when loosening.

Why the heat discoloration of the rocker arm ends. Bill
Eric,
Are there really any tricks to replacing injectors, special tools, etc. that would keep an old wrench turner like me from replacing them.
It would appear to me that it's just extremely tedious removing all the crap on top to get to them? I recall the picture of you working on a truck from which you had removed the front wheels and set 'er down on the ball joints! Very clever.
Does one need a Tech II when done or will the ECM "relearn" the new injectors over time?
Sure hoping some after market ones (and less expensive) appear before I need them.
