[QUOTE=HeadsU.P.;1603530328]The thought of drilling ventilation holes in a car part (cap) that is suppose to be somewhat water proof just doesn't sound right.
No thanks.

There was a reason the old "Points & Condenser" IGN style caps had a closable window on the side of the cap.
To keep shet out.[/QUOT

My car sits far more than I drive it. I am much more concerned about moisture accumulation and arcing than dust making though a few 1/4 inch holes. I will see how it goes.

Coat your terminals where the wires go into the cap with Dielectric grease. You may be getting water going through the cap terminals. I also agree the caps with aluminum contacts for the rotor are cheap garbage.

Car was in Central Texas for a few years and now going on 20 years in Northern Virginia. It's always been garaged since I've owned it, bought in 1999.
