Abstract: An apparatus and method for diagnosing mechanical problems in turbocharged engines. In its preferred embodiment, the apparatus consists of a boot that is coupled to a turbocharge system—preferably at the air inlet thereof. The, apparatus further includes a source of air pressure that may be delivered to the turbocharge system, a first pressure gauge to measure the pressure of the air that is being delivered, and a second pressure gauge to measure the pressure of the air within the turbocharge system. Under pressure, and with the engine off, the turbocharge system can be inspected for leaks. In addition, under pressure, the operation of turbocharge system components—such as the wastegate valve/diaphragm and the boost sensor—can also be inspected.
