TURBO TEARDOWN

The components and operation of turbochargers are described, specifically those used in 1978 and 1979 Buick engines. The Buick turbocharged engine is equipped with an Electronic Spark Control (ESC) system which comprises a detonation sensor, a controller, and the HEI (high energy ignition) distributor. The ESC senses engine detonation and adjusts the timing to eliminate the knock. Information is provided for the service specialist in diagnosing problems with the turbocharged engine. Instructions are given on checking the various elements of the ESC system in the case of engine detonation or poor performance. Additional problems associated with the turbocharged engine are described: engine detonation caused by sources other than the ESC system, blue smoke and oil consumption, poor power, engine surges, black smoke, and noise.
