Why would a spark plug wire melt?
From what you’ve described, the cylinder head overheated which caused the wires to melt. Your engine is overheating and the white smoke from the exhaust indicates that the head gasket is blown or cracked.
What could cause a spark plug to melt?
A melted electrode on your spark plugs means that they’ve been running too hot for too long and could burn a hole through the top of a piston. A heavier, oily black deposit means that oil is being sucked down into the combustion chamber, likely via worn valve guides, guide seals or piston rings or a cracked piston.
Can you remove the metal sleeves off of the spark plugs?
Once you wiggle and pull on them you stand a high risk of damaging the spark plug wires! I have the same problem with my 98 dodge ram, there is a metal sleeve that is around the spark plug, there is no way they come off with the plug wire it is not he insulating part of the wire.
Do you need to replace a spark plug wire?
Although procedures for coil packs which are directly mounted on the spark plug may vary between makes and models.

Grab firmly onto the spark plug wire boot, then twist in either direction and pull off simultaneously.
Can You reattach spark plugs after replacing them?
The trick is when reattaching the spark plug wires after you replace the plugs is to use lots of dielectric grease on the porcelain of the spark plug body so the plug wire doesn’t bond to the plug. I normally see this problem with cheaper spark plug wire sets. Once you wiggle and pull on them you stand a high risk of damaging the spark plug wires!
How are spark plug wires set in place?
Route the new spark plug wires away from the exhaust manifolds or other metal objects. This protects them from the heat of the manifolds and reduces capacitive voltage loss between the conductor and metal surfaces. Good spark plug terminals are made with a snap ring that give a metallic “click” or “snap” when they are properly set into place.
How to loosen a spark plug on a ratchet handle?
4 Stick the square end of your ratchet handle into the square hole in the spark plug socket. Adding a couple of extensions between the handle and the socket may help you move the handle freely from side to side without hitting anything. 5 Loosen the spark plug by turning it counterclockwise.
