Should you grease glow plug threads?
No don’t use copper grease! The electricity going through the glowplug can react with the copper grease and cause it to seize in even worse! Use a ceramic grease especially for this purpose. Also if you want a safe way of doing this DONT START THE ENGINE WITH THE GLOWPLUGS HALF OUT.
