Injector torque ?

I pulled out my injectors and pressure tested, they pop at 2,200 psi is that in spec? What is the torque on new copper rings?

The torque is 50 ft lb if i remember right. 2200 psi sounds good.

More important is that they all pop at the same pressure. Yes 2200 is good as long as they don't leak down after popping.

2200 is a good number indeed. but like stated, you need to make sure that all the injectors pop within the same number. Otherwise your could end up with misfires, or firing to late/early.

80,000 miles on a set of 6.5 injectors is very close to the end of there lifespan. Although at best they last till 100,000, if you tow it will be around 80,000.
