I was replacing my valve cover gaskets and tried to remove my plug wire...ended up ripping the metal clip off and was stuck on the plug. What is the correct technique to repairing this? Seen youtube videos with 2 different ways as far as the wire being exposed vs leaving it insulated and then folding back into clip. And after learning the correct technique, would it affect anything to trim all plug wires so everything looks tight to get rid of slack in the wires? Plug wires are tay84004
