Keep your back axle breather clear to avoid moisture build up

Ralph Hardwick recently purchased an MGBGTV8 and dropped it off with Brown & Gammons for a check over and service during which Ralph reports "they picked up a few issues, so it will remain there for a while until they are sorted. One issue they found was it appears that the rear axle breather was blocked - the resulting condensation build up together with having only covered 1,000 miles in the last seven years, has caused some corrosion and bearing issues".
