The kit combines a regulated air source interface, two gauges, multiple spark-plug adapters and flexible hosework so you can pressurize each cylinder and observe leakage percent and pressure loss locations. It’s built for a wide range of petrol 4-stroke engines and comes in a compact carrying case with clear fittings for both tight and accessible plug wells.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the leak down tester reveal engine problems?\u003c\/h3\u003e\n\n\u003cp\u003eBy introducing compressed air into a cylinder at top dead center, the tester shows how much pressure the cylinder loses and where it escapes. The dual-gauge arrangement gives both reference pressure and leakage percentage so you can distinguish between minor and severe failures.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eMeasures leakage percentage to quantify condition of rings, valves, or head gasket.\u003c\/li\u003e\n  \u003cli\u003eDetects locations of leaks by listening or feeling (intake, exhaust, crankcase, coolant passages).\u003c\/li\u003e\n  \u003cli\u003eDual gauges provide input and leakage readouts for reliable comparison.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat comes in the kit and how do I fit it to different engines?\u003c\/h3\u003e\n\n\u003cp\u003eThe kit contains adapters and connectors sized for common spark plug threads plus a flexible hose to reach recessed wells. Lightweight yet sturdy fittings provide universal fitment for most domestic and imported cars and trucks without special tools.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eIncludes 12mm and 14mm spark plug adapters for common thread sizes.\u003c\/li\u003e\n  \u003cli\u003eFixed connectors M14 x 26mm and M16 x 26mm for direct attachment options.\u003c\/li\u003e\n  \u003cli\u003e480mm flexi hose and quick-connect regulator for tight or awkward access.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow accurate and safe is the testing process?\u003c\/h3\u003e\n\n\u003cp\u003eAccuracy depends on proper setup: cylinder at top dead center, valves closed and correct adapter seal. The kit’s air regulator and calibrated cylinder leakage gauge let you control test pressure and read leakage without over-pressurizing components.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eUse regulated shop air and set to recommended test pressure to protect valves and seals.\u003c\/li\u003e\n  \u003cli\u003eCalibrated gauge shows leakage percent so you can compare cylinders evenly.\u003c\/li\u003e\n  \u003cli\u003eFollow instructions for TDC and valve positioning to avoid false readings.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhen will a leak down test save time over other diagnostics?\u003c\/h3\u003e\n\n\u003cp\u003eA leak down test quickly isolates compression loss sources before you commit to expensive disassembly. It’s often faster and less invasive than tearing down heads or pulling pistons when diagnosing poor compression, rough idle, or oil consumption.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eUseful as a first-line check after a failed compression test.\u003c\/li\u003e\n  \u003cli\u003eHelps prioritize repairs by identifying leak location (valves, rings, head gasket).\u003c\/li\u003e\n  \u003cli\u003eReduces unnecessary engine teardown by confirming the true fault area.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWho is this for: The LEIMO KPARTS Cylinder Leak Down Tester suit mechanics, mobile technicians, hobbyists and small workshop owners who need a portable, practical tool for engine cylinder diagnostics. It’s appropriate for anyone servicing petrol four-stroke engines in passenger cars, light trucks and many imported models where spark-plug access is limited. The kit’s range of adapters, paired gauges and clear regulator control make it useful for both routine troubleshooting and pre-purchase inspections without needing advanced shop equipment.\u003c\/p\u003e\n\n\u003cp\u003ePackage note: the kit ships in a molded carrying case containing the 480mm flexible hose, 12mm and 14mm adapters, fixed M14 x 26mm and M16 x 26mm connectors, pressure gauge, cylinder leakage gauge, air regulator, instruction sheet and support contact for after-sales service and returns.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Can this kit test diesel engines?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: This kit is designed for petrol 4-stroke engines; diesel cylinder pressures and fittings differ, so it’s not recommended for diesel compression testing.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Do I need compressed air supply to use the tester?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes — a regulated compressed air source is required; use the included regulator to set safe test pressure levels.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"LEIMO KPARTS","offers":[{"title":"Default Title","offer_id":48086785065118,"sku":"B07W9FXKTF","price":55.36,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0781\/2041\/9486\/files\/leimo-kparts-kit-front-layout.jpg?v=1785905098","url":"https:\/\/northtrailauto.ca\/products\/leimo-kparts-cylinder-leak-down-tester-kit-dual-gauge-compression-leakdown-12-14mm-adapters-carry-case","provider":"North Trail Auto","version":"1.0","type":"link"}
