A cylinder contribution test is pretty much worthless with anything other than an original, black cam position sensor installed. Even then, I wouldn't change an injector based solely on that result.

glow plugs
Have you tried the dealer in most cases their more adept to helping you as to where and how to do it, I would ask the guys in the parts department, don't waist your time asking the mechanic. Because more then not he'll just shack his head as to I don't know! And also have you tried U-tub.

No, it will not. There's no need to worry about the oil around the glow plugs. There isn't enough there to cause any problem when it runs into the cylinders. The oil that runs into the cylinders when an injector is removed comes from the high pressure oil rail in the head, so draining the pan has no effect.

Most people, myself included, don't drain the oil rails. It's common to just pull injectors 7 & 8 first and let all the fuel and oil collect in those two cylinders. Then just evacuate it with a tube and syringe or Mityvac.
