Britain Built a World-Beating Engine - Then Destroyed It at the Factory

In 1973, a small team in Coventry built a cylinder head so clever it won a Design Council award - sixteen valves, one camshaft, an answer the rest of the industry needed two camshafts and a bigger bill to match. Within five years it had a reputation for destroying itself. Both of those things are true. And the reason has almost nothing to do with the engineering. The proof has been sitting in a motoring magazine since 1976: the log of a Triumph Dolomite Sprint owner in Lincolnshire who watched his own engine cook itself - and then, having listed every fault it gave him, defended it. Because he also wrote down the cause. One line. And it moves this whole story off the drawing board and onto the shoulders of the company that built the car. This is the story of the Dolomite Sprint - the engine that was Swedish before it was British, that won championships while its reputation rotted, and that is quietly coming back from the dead today. British Leyland built one of the most advanced engines in Europe. Then it let the car around it down. Did your family ever have a Dolomite - a Sprint, or one of the plainer ones? And be honest: did it ever get through a winter without a garage bill?
