information, mods and maintenance of the MG MGB classic car including shows, clubs, meets, places to visit, general information and reviews. Also info and updates of the tips, tuning, servicing and repairs, including diy modifications I have made on my own classic car – a 1975 MGB Roadster. You are welcome to add your comments to any of my posts.
The mgb has quite a few drainage points that drains water that collects from the inside (especially the open top version) and from the sills and floor box sections.
These can easily get blocked with underseal and other debris.
