Valve Stem SealWe list this valve stem seal as an aftermarket replacement, a regular reach for fleet managers running mixed-make yards stocking common engine wear items. It rides on the valve guide and stops oil from running down the valve stem into the combustion chamber, a common culprit behind blue exhaust smoke at startup. Keeping pieces like this in stock means a downed truck can get back to moving freight the same shift instead of waiting on a dealer order.
