One New Aftermarket Replacement Valve Guide for Caterpillar (Cat) D336 and 1676 Engines
This aftermarket replacement valve guide fits the Caterpillar D336 and 1676 engine families. The valve guide is a precision cylinder-head component that supports and aligns the intake or exhaust valve stem, maintaining proper seating and sealing for efficient combustion.
