Opti spark install
When installing the opti spark is there a right or wrong way to install it? Can you install it wrong? This is a 96 with a lt4. I am aware of how it fits into the cam but my question is is there more than 1 way to do it?

Two other things we did on my last opti install was to loctite the rotor screws inside and add washers to the cover bolts to add alittle more space.
Firmly believe banging against the cover caused the screws to come loose inside which caused the rotor to break up and take out the opti sensor as well. Even with my new Delteq ignition, this caused failure.
