View Full Version : Cap And Rotor

09-25-2003, 07:23 AM
Dirt late model, 420ci, appx. 720 hp. MSD dist, 6T box. How long should the cap and rotor last. I get a lot of green corrosion after appx. 20 nights. Is this normal or should I look for another problem. Should the cap and rotor last more than 20 nights? We are in central IL. Weather varies from hot and humid to cold and damp. Thanks

Is your cap vented to allow the ionized gases that build up in the cap to release? Venting the cap may reduce the corrosion problem. Do you spray wash the engine off after a night of racing? If there is moisture built up in the cap and you run the engine then you are going to see corrosion build up a lot quicker.
