So I pulled my injectors, per the DIY I just posted and some questions previously. What struck me was that despite my car having been sitting for over two weeks without being run, I pulled the injectors and four of the five were very wet with fuel and there was fuel at the seat bottom where the injector touches the prechamber. Is this normal?

Hopefully using an inpact gun to carefully remove them, I didnt cause them to leak down, though if that was the case, I guess no big deal.

Anyway, some pictures:

#1 (injector furthest to the front is #1, furthest to the back is #5) came out quite wet on the sides.



And it was dirty:



Ditto for #2:



And #3:



But #4 came out very dry:



And number 5 was wet again:



Here they all are:



And the nozzle tips:

#1:



#2:



#3:



#4:



#5:




Though #4 was the dryest, it did have the most soft carbon deposits on the outer edge. It also had junk in there as soon as I pulled it out:



The rest had what looked like rusty fuel, it was murky brown, not clear yellow, as if there was rust mixed in fuel. I blotted it all out and vacuumed all the threads and seats so they were clean prior to plugging them with paper, but here are some pictures of what Im talking about:









Is this right? My indy mentioned when I started my car cold that he heard an injector "leaking". Could that actually be four of them leaking? Or was injector #4 dry because it had already leaked out prior, so it is actually the guilty one? Any thoughts?

And also to ask a real dumb question, where are the heat shields? Per my pictures, are they stuck to the injector face, or are they still in the prechamber?

Thanks!
