Abstract
A method of testing an internal combustion engine to detect engine defects. After the engine has been assembled, the engine is cranked, gas under pressure is injected into the intake ports, and the pressures developed at the exhaust ports as the engine is cranked are noted and evaluated. The pressurized air injected into the intake ports amplifies the pressure signals developed at the exhaust ports so as to provide more accurate identification of engine defects and detect engine defects that might go undetected utilizing prior art technology.
