Still haven't addressed a fresh air entry source to help purge those hot
gases.
Early MGB engines used a wire mesh filled oil filler cap to handle this
area. I am not seeing any fresh air entry for our Healeys except for maybe
the small hole in the original oil filler cap but that wasn't its intended
purpose. I guess the Healey designers didn't think that fresh filtered air
was an issue.
