When I pull the two injectors, is there anything that I'm looking for in particular?

So, there's a chance that it could have chewed up the washer? That can't be good.

if its loose, the copper washer burns up and can burn up the injector after

arguing about it wont do anything, go yank it out and look

So, today I pulled injectors 1 and 3. As I was preparing to loosen the lower 8mm bolt holding the injector in, I found that it was barely hand tight. I did my best to torque them to 120 in/lbs when I reinstalled them after installing new seals, but all I had at the time was my Harbor Freight torque wrench. Should it be that loose? Could that cause a problem? Also, after I pulled the injectors today I could see some trash down in the injector bore. Could any of this cause the blue smoke issues?
See the pictures that I took of the injectors too.

define trash in bore, if its just carbon then you had a leaking copper washer from injector being loose and caught it fast.

re torque injectors, run with valve covers off and see if all spurt same amount

I had two get loose on my at 120, some have said to use 140 in pounds or set them when engine is hot
