Bicos Cylinder Leak-Down Tester Kit with Dual Gauge – Pressure & Leakage Rate Testing for Gasoline Engines

Overview

The Bicos Cylinder Leak-Down Tester Kit is a versatile diagnostic companion for gasoline engines. It blends a precise dual-gauge system with flexible connectors and a durable manifold, designed to help you assess cylinder pressure and leakage tendencies with confidence. Whether you’re a DIY enthusiast or a professional technician, this kit aims to streamline engine checks without sacrificing accuracy.

Key capabilities

• Dual gauge design enables simultaneous monitoring of cylinder pressure and leak rate, with readable 3-inch gauges and a practical 0–100 psi / 0–7 bar range.
• High-contrast readings with accuracy around ±0.5%, helping you interpret results quickly and reliably.
• Robust leak detection features that support identifying common engine faults such as worn rings, valve issues, or head-gasket concerns when used with an air source.

What’s included and how it helps

• Versatile connectors and adapters (universal push-on types and threaded adapters) allow compatibility with a wide range of petrol engines, reducing setup time.
• Long and short hoses, plus an extension rod, extend your reach and simplify testing in cramped spaces or tight engine bays.
• Durable aluminum manifold body, AR2000 pressure-regulating valve, and a robust air plug assembly provide stable pressure control for repeatable tests.

Setup is straightforward: attach to a suitable air source, seal into the spark plug wells with push-on connectors, and read the dual gauges to gauge both pressure and leakage tendencies. The kit is designed to be compatible with most gasoline engines that use spark plugs within typical dimensions, making it a practical choice for regular diagnostics.
