Look at this injector!

I posted about my problem a week or two ago and after researching here, and some helpful posts, I ordered injectors and two replacement kits. So, I got them out this morning and look at this thing:

What ELSE, if anything, do you think is wrong? I'm definitely replacing the supply lines too.

The other three on the passenger side look fine but yeah I'm replacing them all.

I have no experience under the valve covers of a Duramax, but wondering if someone that does, could also comment on the discoloration on the rocker arms shown in the picture?

Every single one is like that in the exact same place. To me that seems like a manufacturing attribute. Everything else inside looks perfectly clean. I change the oil regularly.

The rockers are like that from heat in the mfg process.

The injectors get that rusty gunk from the high pressure lines. Crap gets beteen the line nut and line. It does not get into the injector bowl until you remove the line.
