so after a cylinder contribution test showing cyl 8 had an issue i pulled the valve cover off and in the video you can clearly see cyl 8 when disconnected didnt make much of a difference...and all the injectors were squirting oil ok... maybe cyl8 a little to well....so to narrow it down to injector or cylinder without doing a compression test or switching injectors is there any way to tell if its the injectors or the cylinder?
if someone could post a link to how to do a diesel compression test that would be great
