Valve Stem SealThis valve stem seal ships as an aftermarket replacement and is a go-to for independent forklift repair shops keeping fleets running between scheduled rebuilds. 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.
