HEI Ionizing Issue
So I have read about this in the past. About every 3,000 to 5,000 miles I will have to pull my HEI cap and clean it out due to some type of corrosion buildup on the brass tabs for the plugs. Also some build up on the rotor yet minimal.
I read somewhere that it is Ionizing Air in the cap that causes this. I will run rough upon cold start up until fully warm. Slowly causes a loss of mileage and power. I have to scrap, sand it off and spray out the cap with carb clean and re-assemble. Is there a way to prevent this from happening? Remember hearing about some drilling a hole in the cap yet this will let ambient moisture in most likely causing more issues. Would love to hear the cause and or any mods that can be done to prevent this from occurring. |
