Engine Pressure Drop Tester for Gasoline and Diesel Engines

The engine pressure loss test allows for a targeted assessment of the tightness of individual cylinders and helps further narrow down the cause of abnormal compression readings. To do this, the combustion chamber is pressurized with workshop compressed air while the intake and exhaust valves are closed. The test measures how much pressure is lost through the cylinder or combustion chamber. At the same time, the air leak can provide clues as to whether the leak is located, for example, near the intake valve, exhaust valve, piston rings, or cylinder.

Autotestgeräte Leitenberger offers analog engine pressure loss testers for gasoline and diesel engines, special kits for various vehicles and motorcycles, as well as the digital DRV 05_BT compression and engine pressure loss tester with Bluetooth transmission and documentation capabilities. A comprehensive range of adapters enables testing via spark plug, glow plug, or injector ports. OT adjustment tools are also available to ensure correct piston positioning.
