Lisle 36200 Valve Keeper Remover and Installer - Fast Valve Work

In this review the Lisle 36200 Valve Keeper Remover and Installer is judged as a straightforward, purpose-built tool for anyone who needs to remove and reinstall valve keepers on overhead valve engines. The single biggest reason to buy is its combination of simple mechanical action and a built-in magnet that secures the tiny keepers during service, which makes disassembly and reassembly noticeably faster and less fussy than working with pliers or improvised tools. For home mechanics and professional techs who work on engines in the 5/16' to 3/8' range, this tool saves time and reduces dropped parts.

Key Features

• Quick keeper removal: The push or tap design lets users remove valve keepers rapidly without complex setups, speeding valve head work.
• Integrated magnet: A magnet in the tool body captures keepers so they do not fall into the cylinder head or get lost during disassembly.
• Works for common keeper sizes: The tool covers a range from 5/16' to 3/8', which fits many overhead valve engines used in cars and light trucks.
• Installer function: Keepers can be loaded into the installer and pushed or tapped into place for quick, controlled reassembly.
• Bench or vehicle use: The compact tool is usable on the car or on a work bench, making it practical for in-field repairs and garage work.

Who It's For

The Lisle 36200 is aimed at DIY mechanics, backyard restorers, and professional technicians who need a small, reliable device to speed valve spring removal and reinstallation on overhead valve engines that accept 5/16' to 3/8' keepers. If someone routinely performs valve jobs or wants to avoid renting larger compressors, this tool reduces time and frustration.

It is less suited to engines with keeper sizes outside the 5/16' to 3/8' range or very compact cylinder heads where the tool's size may be awkward; customers have mixed feedback about fit on smaller engines, so those working only on motorcycles or micro engines should verify fit first.

Pros & Cons

Pros

• Captures keepers with a strong magnet, preventing dropped parts during disassembly.
• Simple push-or-tap operation removes and installs keepers quickly without a spring compressor.
• Durable, well-made design that feels like a quality tool worth the cost.

Cons

• Size can be too large for some smaller or tightly packed engines, limiting fit in tight valve covers.
• Covers only the 5/16' to 3/8' range, so it is not universal for all valve trains.

Specifications

Our Verdict

The Lisle 36200 is a compact, effective tool for anyone who regularly removes and installs valve keepers in the 5/16' to 3/8' range. Its magnetic capture and simple push-or-tap operation make valve jobs faster and reduce the risk of lost parts, offering clear value for home mechanics and shops. Buyers should confirm fit on very small or crowded heads, but for compatible engines it is an economical alternative to more complex setups.
