Designed for most gasoline engines with spark plugs up to 20 mm, the set connects to an air compressor (not included) and helps you identify where combustion gases are escaping when the piston is at top dead center.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the Prokomon tester reveal where compression is escaping?\u003c\/h3\u003e\n\n\u003cp\u003eThe tester pressurizes a single cylinder through the spark plug hole while a dual gauge shows the supplied pressure and the percentage leakdown. Listening and observing where air vents (intake, exhaust, crankcase or cooling system) lets you locate worn rings, leaking valves, cylinder cracks or head gasket paths. The dual display simplifies interpretation by giving an immediate leak percentage alongside the reference pressure.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eUses compressed air to pressurize the cylinder via spark plug port.\u003c\/li\u003e\n  \u003cli\u003eDual gauge reads 0–100 psi (0–7 bar) and 0–100% leak with ~0.5% accuracy.\u003c\/li\u003e\n  \u003cli\u003eAudible and visual clues show leakage route (intake\/exhaust\/crankcase\/head).\u003c\/li\u003e\n  \u003cli\u003eRequires setting piston to top dead center on compression stroke before testing.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat parts are included and how do they improve testing flexibility?\u003c\/h3\u003e\n\n\u003cp\u003eThe kit expands a basic manifold package with multiple adapters and connectors to fit a broad range of petrol engine spark plug wells. It includes straight and angled push-on fittings that avoid threading into delicate spark plug wells, plus threaded adapters and an M14 aluminum extension rod for deep or recessed plugs. An 18-inch hose, extension hose and a pressure regulator valve let you control and route air supply easily during inspection.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eDouble-gauge manifold with pressure regulator (AR2000 style valve).\u003c\/li\u003e\n  \u003cli\u003e18-inch rubber hose plus an extra extension hose for reach.\u003c\/li\u003e\n  \u003cli\u003eStraight and angled universal push-on connectors for non-threaded fit.\u003c\/li\u003e\n  \u003cli\u003eTwo threaded adapters and an M14 extension rod for recessed plugs.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow accurate and compatible is the gauge assembly?\u003c\/h3\u003e\n\n\u003cp\u003eThe dual gauge reads pressure and leak percentage across a practical range for petrol engines: 0–100 psi (0–7 bar) and 0–100% leak. Accuracy is approximately 0.5%, suitable for workshop diagnostics where identifying significant leakage is the objective. Compatibility is broad for spark-ignition engines with spark plug diameters up to 20 mm, but always verify adapter fit before applying pressure.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003ePressure range: 0–100 psi (0–7 bar) with ~0.5% accuracy.\u003c\/li\u003e\n  \u003cli\u003eDesigned for gasoline engines with spark plugs within 20 mm diameter.\u003c\/li\u003e\n  \u003cli\u003eRegulator knob adjusts input air pressure and locks for stability.\u003c\/li\u003e\n  \u003cli\u003eAmerican-style air plug on manifold for standard compressor hoses.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat safety and usage tips should you follow when testing?\u003c\/h3\u003e\n\n\u003cp\u003eUse the tester only with the engine at rest and the cylinder set to top dead center on the compression stroke to avoid injury or damage. Always wear eye protection, depressurize the system before disconnecting adapters, and confirm hoses and fittings are snug to prevent sudden disconnection. Do not exceed recommended input pressure and use an air compressor with a reliable regulator for repeatable results.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eSet piston to top dead center on compression stroke before testing.\u003c\/li\u003e\n  \u003cli\u003eWear eye protection and verify secure hose connections.\u003c\/li\u003e\n  \u003cli\u003eDo not exceed safe compressor pressure; use regulator control.\u003c\/li\u003e\n  \u003cli\u003eRelease pressure before removing connectors or adapters.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWho is this for: The Prokomon Engine Cylinder Leak Down Tester Kit is aimed at DIY mechanics, home garage technicians and professional service shops who need an affordable, portable way to diagnose combustion chamber leaks in spark-ignition engines. It’s useful for pre-purchase inspections, troubleshooting loss of power, and confirming repairs that affect rings, valves or head gaskets.
