Adjusting the valves on a LS motor is an important part of keeping your engine running in peak performance. The process can be intimidating for those unfamiliar with it, but it doesn’t have to be that way. With a few tools and some patience, you can easily adjust the valves on any LS motor. First, start by determining which valve needs adjustment. Many times this will be indicated by a loud tapping sound coming from the valve train or excessive exhaust smoke when starting up the vehicle. Once you’ve identified which valve needs adjusting, remove both its rocker arm covers and loosen its locknut so that you can turn its adjusting screw using an adjustable wrench or socket set if necessary. Turn the screw until there is zero lash between the rocker arms and pushrod (you may need to apply slight pressure). Finally tighten down the locknut and replace both covers before moving onto another cylinder if needed. This process should ensure your LS motor runs properly for many miles ahead!
