Mine are "holy shit thats tight" lol. Anythjng else seams to leak. im not saying to do that,id try to torque them to spec and if you have a leaker snug it accordingly from there.Also screw both ends down evenly seams to be the best.

Personally I tighten, crack them loose and re tighten. Don't know why I do that, but its been working so far

Sounds like you don't have a leak

It seems like I don't then unless when i put the lines back on without the valve covers i tightned the crap out of then. but if my oil keeps climbing after this the reman injectors will be coming out! Still got a year warranty on them.

From merchant auto, I have done every test possible return volume test, vacuum test, compression test, replaced the cp3, and still making oil? If its still doin it after this all the injectors are coming out.

A few years ago II sent me a set of injectors where not one of the injector tips was torqued down and they all leaked into the heads. It was a pain in the ass to figure out because they where hand tight. Possibly something look at, I even replace all of the high pressure lines with new ones before figuring it out.

I don't think this would e an issue because they were Bosch remans, the ones you would get from the stealer ship, but ill
Keep it in mind. Andrew seems like a real honest guy to me so I'm not pointing any fingers I'm just weeding out the problem.

Yeah I'm not pointing fingers either, anything is possible someone at Bosch could of been having a shitty day or whoever rebuilt the injector didnt care. Half the reman lines I have ordered were junk thats why I bought new ones.
