Upon pulling #1 glow-plug to see what was in there - The plug was VERY tight. I almost thought I might break it taking it out!
When It did come out, I discovered it has the 5v plugs, not the original 7v.

Are the plugs supposed to be that hard to get out? Do the new 5v plugs fit in the block differently than the original ceramic?

Is there a trick to getting the plugs out easier?

regards, dw

Engine at operating temps should make them come out easier.

See my thread about my crazy #2 glow plug below. The torque spec for glow plugs is only 9Lb/ft. That is super low. Other than my problem with the #2 plug, all others were super easy. Don't forget to put antiseize on the threads!

glad to read I'n not the only one to have a problem. Also on the number 1 plug. After working it back and forth, with liberal WD-40,it it came out. Screwing in the new plug is tight even with anti seize, I'm not sure it's in all the way. The other 3 plugs were a breeze.

still deciding what else I want to do

I was advised NOT to install with anti-seize because it can interfere with electrical conductivity. I believe there is a version of anti-seize that is conductive, like dialectic grease, but I do not recall who makes it.

Actually dielectric grease is non-conductive. Confusing since we are told to apply it to electrical connections, but its real purpose is to seal out air and moisture from corroding the contacts. The grease is actually (hopefully) squeezed out from the contact points.

I used the common copper colored anti seize on both my CRD's glow plugs without problems. Again, it is squeezed out from the thread contact points that conduct to the cyl. head, and it fills the gaps, preventing corrosion.

Correct. The reason for using antiseize is the galvanic corrosion between the steel jacket of the glow plug and the aluminum head. I also use the copper antiseize. When copper oxidizes, it only forms the green hue that we are all aware of. Oxidized steel forms rust. Rust is far more harmful to the close threads of the outer steel jacket of our glow plugs. Copper is very conductive material.

By definition a dielectric is an insulator so the name kind of gives it away

X2, no matter what you put on the threads, it is always going to hit metal to metal at many points.

You would think! But most people see "electric" and think that it conducts. Common misconception out there.
