"The Mini-Minors and Austin Sevens have proved very successful, and although it is rather early in their lives to start thinking about complete over-hauls, there is one fault which developed on some of the earlier models. There was a tendency for a slight oil leak from one of the rear engine oil seals, into the clutch housing, causing clutch slip. A modified seal is now available." PM May 1961
