I have a dt466e that was blowing a lot of grey smoke (un burned diesel). Customer had used injectors from original motor and wanted to try them prior to having injectors tested and or rebuilt. When I installed the used injectors the motor would not turn over,it hit hard like hydrostatic lock. I pulled the injectors motor turns over fine, but shoots oil out of the #6 hole, would this be normal oil pressure used to control the injectors as "snafoow" refers to in the thread on dt466 no start? If so how can I remove the hydrostatic pressure when I reinstall the injectors?

Very important to drain the high pres. oil from the rail (half drive ratchet plug) before removing injectors or you could bend a rod. If oil does get on top piston crank engine over with ecm unpluged to cleen out.
