A leak-down test tells you exactly what and where. This Cylinder Leak-Down Tester pressurizes each cylinder and measures how much pressure is lost — pinpointing whether the leak is past the rings, valves, head gasket, or cylinder wall, so you can make the right repair decision before it becomes a catastrophic failure.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMeasures cylinder leakage percentage\u003c\/strong\u003e — precise diagnosis beyond what a standard compression test can provide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIdentifies leak source\u003c\/strong\u003e — worn piston rings, burnt or leaking valves, head gasket failure, or cylinder wall scoring\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual-gauge design\u003c\/strong\u003e — supply pressure and leakage percentage displayed simultaneously\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWorks on petrol and diesel engines\u003c\/strong\u003e — includes adapters for most spark plug and glow plug thread sizes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProfessional-grade accuracy\u003c\/strong\u003e — suitable for workshop and advanced DIY use\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eCompatible with:\u003c\/strong\u003e Most petrol and diesel engines — universal fitment via included spark plug and glow plug thread adapters\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat's in the box:\u003c\/strong\u003e Cylinder leak-down tester kit with dual gauges and thread adapters\u003c\/p\u003e","brand":"Wrench Haus","offers":[{"title":"1 Kit","offer_id":42368269877333,"sku":"WH-DIA-001","price":79.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0638\/9769\/8389\/files\/S4754b249b1ef472695617e18edde24caL.webp?v=1776482003","url":"https:\/\/www.wrenchhaususa.com\/products\/automotive-compression-leakage-detector-kit-cylinder-leak-tester-tools-auto-engine-repair-pressure-gauge-diesel-test-tool-kit","provider":"Wrench Haus","version":"1.0","type":"link"}
