INFO
PAC-1218 LS Valve Spring Set is intended for owners, engine builders, and repair technicians servicing the listed valvetrain configuration when camshaft, lifter, rocker, spring, or related valvetrain wear has been confirmed during diagnosis. Within Valvetrain, the component coordinates valve opening and closing through the camshaft, lifters, and related valve-motion components. This SKU is configured around GEN Ⅲ / Ⅳ engine and engine valvetrain position, keeping the replacement aligned with the original component's operating role instead of changing the vehicle's factory system type. The design supports a focused repair of the affected assembly while retaining the application-specific mounting, connection, and operating requirements documented for this product.
Use PAC-1218 LS Valve Spring Set after diagnosis has isolated persistent valvetrain ticking, misfire, rough running, or wear found on matched camshaft and valve-motion components. The replacement replaces the matched valve-motion components so camshaft rotation can be transferred through the specified valvetrain configuration. Inspect oil supply, cam lobes, lifter bores, rocker contact points, timing components, and sealing surfaces during disassembly. Verify lubrication and valve-motion geometry before the engine is returned to service. This application uses the GEN Ⅲ / Ⅳ engine, so the engine code and factory configuration must agree with the vehicle being repaired. Follow the required timing, lubrication, preload, and torque procedures, then verify valve motion before startup. After assembly, verify normal system operation and correct any separate fault source found during diagnosis.
