Orion Motor Tech Valve Spring Compressor Kit — 8/16/24mm Adapters, Case & Pliers for OHV/OHC Engines

Orion Motor Tech's OMT Valve Spring Compressor kit is a complete, heavy-duty tool set for removing and installing valve springs and keepers without removing the cylinder head.

If you service cylinder heads, this kit brings the clamps, adapters, pliers, and seal installer needed to compress, hold, and replace valve springs on OHV and OHC engines. Built from thick steel with corrosion-resistant finishes and supplied in a blow-molded case, the set is designed to speed one-person jobs and keep components organized between visits.

How does this kit remove valve springs without lifting the cylinder head?

The compressor clamps and adjustable pressure lever let you compress valve springs while the head remains on the engine. The kit installs over the valve guide area so retainers and keepers can be released and reinstalled safely.

• Multi-point adjustable pressure lever for controlled compression
• Mounting brackets that anchor to valve locations while working
• Straight and curved pliers reach tight retainers and keepers
• Adapters sized for common valve stem diameters to fit most engines

Which engines and valve sizes are compatible with this set?

This kit supports typical automotive valve stems and is compatible with 8 mm, 16 mm, and 24 mm valve systems used across OHV and OHC gasoline and diesel engines. The included adapters and holders cover a wide range of makes and models.

• Adapters and holders for 8 mm, 16 mm, and 24 mm valve stems
• Works on overhead valve (OHV) and overhead cam (OHC) configurations
• Suitable for gasoline and diesel passenger vehicle engines
• Design accommodates common retainer and keeper types

What features make the tools easier and safer to use?

Ergonomic knurled handles, non-slip plier grips, and a corrosion-resistant finish help improve control and durability. The compressor's adjustable points and mounting brackets reduce slippage so you can work confidently on a hot or cramped engine bay.

• Knurled seal installer handle for firm, non-slip control
• Curved pliers for access behind springs and retainers
• Protective coatings to resist corrosion and wear
• Sturdy steel construction for repeated heavy use

What is included for storage and jobsite transport?

The complete set ships in a blow-molded case that organizes each piece and protects finishes during transport. Every adapter and tool has a dedicated slot so parts stay secure and are easy to inventory before leaving the shop.

• Blow-molded storage case with custom compartments
• Individual slots for pliers, adapters, and compressor components
• Lightweight case design for convenient carrying between jobs
• Case protects tools from moisture and workshop debris
