Vacuum Gauge Reading for Diagnosing Problems and Tuning Up Engines
Vacuum Gauge Reading. The drop will be from the steady reading shown by the pointer to a reading of 10″ to 12″, or less. Some gauges read the complete range and others can only read a portion of the range, usually used for very low pressures.
Vacuum Gauge Reading for Diagnosing Problems and Tuning Up Engines
There's a good chance the vehicle has jumped timing. How is a vacuum gauge reading taken? Quick guide to vacuum gauge readings. By measuring vacuum under different engine loads and conditions, you can track down problems within your engine and make the necessary adjustments or repairs. Intake manifold vacuum is a key indicator of engine performance. This can be used to troubleshoot issues with a system or to determine if a system is operating correctly. Web cylinder head gasket leakage with the engine idling, the vacuum gauge indicator will sharply drop every time the leak occurs. Some gauges read the complete range and others can only read a portion of the range, usually used for very low pressures. A vacuum gauge reading can be used to identify the amount of vacuum present in a system. This reading indicates late valve timing.

Web normal vacuum gauge reading (image/onallcylinders) this a normal reading—between 17 and 22 inches of mercury. Web with the engine at idle, the vacuum gauge pointer will drop sharply every time the leak occurs. If you’re at altitude, these readings may be lower (1 inch of mercury for each 1000 ft. This leak should be easy to find because it would be making a loud hissing noise. This reading indicates late valve timing. How is a vacuum gauge reading taken? The drop will be from the steady reading shown by the pointer to a reading of 10″ to 12″, or less. The drop will be from the steady reading shown by the pointer to a reading of 10 in.
