The Orion Motor Tech OMT Valve Spring Compressor is a full cylinder head service kit for compressing, removing, and installing valve springs and keepers without taking the head off the engine.

When you need to service valve springs, retainers, and valve stem seals on 8, 16, or 24 mm engines, this Orion Motor Tech kit brings the tools and organization required to work on both OHV and OHC engines. Built from heavy-duty steel with corrosion-resistant coatings, the set is designed to speed jobs, improve reach into tight ports, and keep small components secure during engine service. The kit ships in a blow-molded case so every piece stays protected and easy to carry from garage to job site.

How does this kit let me remove and reinstall valve springs without removing the cylinder head?

The compressor’s multi-point adjustable pressure lever and mounting brackets clamp onto the valve spring assembly and compress the spring while giving access to the keepers. With the straight and curved pliers you can reach into confined spaces to extract retainers and keepers safely. The included adapters and knurled handle make seating valve stem seals and reassembling components more controlled.

• Multi-point adjustable lever for steady compression
• Mounting brackets that secure to the valve train area
• Straight and curved pliers for restricted access
• Knurled seal installer handle for positive grip
