I have an LT1 M6 was wondering what it takes to change the plug wires and the cap and roter if it is like a 4 hour job like replacing the plugs were. Those of you with LT's know what im talking about.

 

Just take your time with it. make a day of it and make sure you have an E4 torx socket for the cap, you may even have to have the bit also for the rotor. you use to only be able to get it from snap on but I think you can find them at autozone or pep boys now. you have to pull the air pump and water pump to get to the cap and rotor. **MAKE SURE** you put the drive coupler for the waterpump back on! It is very easy to forget to do that and it will save you time trying to figure out why it is overheating and then removing the pump again.
