There was a thread I read somewhere that suggested drilling a small hole on the cap and then connecting a small plastic hose (like from a tropical fish tanks clear air hose) from the cap to the engine’s PVC plumbing hose. When the engine is running, you would pull a slight vacuum in the distributor, continuously purging the ozone laden air inside the cap and replacing it with fresh outside air to compensate for the vacuum.
Interesting concept….They make little brass hose inserts for use with compression fittings that fit the small hose that would make a easy connection to the cap.…and even on a damp day, the air in the engine compartment is hot and dry…The newer style MDS caps actually have a vent in them that could be used as a connection point for the hose …Interesting idea…Maybe I should patent it?
