Prokomon Engine Cylinder Leak Down Tester Kit – Dual-Gauge Leakdown Tester for Gasoline Engines

Overview

The Prokomon Engine Cylinder Leak Down Tester Kit is a practical tool designed to help you assess engine health by examining cylinder sealing and compression behavior. It pairs with an air compressor you supply and provides clear readouts that can point to potential issues without immediate disassembly. Use it as part of routine tune-ups or troubleshooting to understand how well a cylinder holds air and where to focus attention.

Key benefits at a glance

• Engine fault indicators: The tester can help reveal common causes of compression loss, including worn piston rings, worn valves, cracks in cylinder walls, and blown head gaskets, by monitoring how a cylinder holds and leaks air.
• Dual gauge capability: A single tool measures both the pressure and the leak rate, giving you a quick, at-a-glance assessment of cylinder health with readings ranging from 0-100 psi / 0-7 bar and 0-100% (accuracy listed at 0.5%).
• Comprehensive package: In addition to the base double gauge manifold, rubber hose, and metal adapters, the kit adds 2 universal push-on connectors, 2 threaded adapters, an M14 extension rod, and an extension hose for flexible setups.
• Robust gauge components: The manifold assembly includes an 18-inch hose, an AR2000 pressure regulating valve, an American-type air plug, and a sturdy manifold body. The pressure adjust knob lets you tune input air as needed; pull to use, push to lock.
• Smart accessories for wide compatibility: Straight and angled push-on connectors simplify connections without threading into spark plug wells, and the M14 aluminum extension rod accommodates long or short hoses for varied engine layouts.

Real-life scenarios

Imagine diagnosing a suspect engine during a mid-job check or a home tune-up. The dual readout helps you track how changes to ignition timing or gasket integrity impact cylinder sealing. The long hose and flexible connectors make it easier to work around crowded engine bays, while the extension rod supports positions that would otherwise be awkward or inaccessible.

Usage tips

• Prepare a suitable air supply and connect the tester per the manual.
• Use the push-on connectors for quick, non-threaded connections on petrol engines.
• Leverage the 18-inch hose and extension rod for flexible positioning in tight spaces.
• Follow safety guidelines and readouts to identify potential issues for further inspection or repair planning.
