SPRING-VALVE (Mitsubishi MB0667796)

MB0667796: A worn valve spring can cause incomplete valve closure, leading to reduced compression and potential misfiring. The SPRING-VALVE is an aftermarket replacement part, cross-referenced to Mitsubishi part number MB0667796. This component provides the mechanical force needed to return a valve to its seated position after each opening cycle. Over time, a fatigued spring may allow valve float at higher operating speeds, risking piston-to-valve contact. In a typical four-stroke cycle, the spring must maintain consistent tension across thousands of revolutions per minute. Verify the serial number or application, then call (562) 693-7748. This part is cataloged under the Retaining Ring category.
