Rebuilt my coils today
The wires where rock hard , and the cable for number 4 was broken where it went into the coil body.
I cut them all of and took a grinder to expose the wires where they go along the coil body surface .
Got five feet of 7mm spark plug wire from the store .
Soldered them onto the wire left in the coils .
Covered the cables in a sort of mesh hose ( really dont know what its called in english ) , some heat shrink on the ends , screw the caps back on and hey presto , looks way better than new
All thats left is to fill the parts i removed
With epoxy ,for insulation and to sement everything firmly .
Edit :
Did the epoxy , used a couple of pieces of tape to make a mold , it follows the shape of the coils .
Then used a syringe to fill the cavities with epoxy , two holes , one to fill ,one to let air out , worked like a charm
