The first picture is the injector from the last cylinder back on the passenger side. This is the shape it came out and the dents and scratches were there when I pulled it out. Question about this one is simply whether or not this injector body is usable as is. You can see that there is also discoloration above that first o-ring. Is this normal?
A few of the other injectors that also have the same discoloration in the same place. Not all of the injectors have this discoloration.
On the combustion end of one injector (first one in line on the passenger side), you can see discoloration and what feels like a very thin build up of soot or carbon? None of the other have this build up. I read on a thread someplace that this was a sign of the injector not being torqued properly. This is entirely possible since no two of the hold downs seemed to be tightened the same amount. Some were MUCH tighter than others. I looked up the torque specs for the hold down and my book says 120 inch pounds.
Any way, the next question is whether or not this can be cleaned up and reused.
Finally, I don't see ANY holes in the injector tips for fuel ports. All have some carbon build up, none of the tips are split.
Feel free to chime in with answers! There isn't room in my budget for all new injectors though if that's the only answer...
Lastly, how normal is the oil puddle in the turbo housing like this? I know it comes from the breather being plumbed to the intake but what is the best/economic fix for this?
