| 1360 23.12.36. EXTRACT FROM LETTER RECEIVED FROM THE ROVER CO. Dated 29th Oct. Valve Springs. There has only been one complaint from an owner during 1936 of valve springs broken and that was only because the owner had actually noticed the broken springs. Occasionally when an engine is decarbonized a broken spring is found but its presnce has not previously been noticed. | ||
