Tip of the Day: Working on Valve Lash Adjustments
Most technicians that work on international engines are familiar with valve lash adjustments.
Did you know that the International EGR equipped engines are notorious for loose valves?
Did you know it is not uncommon to have an engine with loose valves right from the factory?
Valve lash adjustments are critical to engine performance, mileage, power, and emissions.
It is common to make a valve adjustment on these engines and have the driver comment that the engine pulls better afterwards and may even notice better mileage.
This is an annual maintenance procedure that is commonly overlooked as the valve cover is not easy to access and remove, but this important procedure is worth the time and effort to ensure the engine is operating at peak efficiency.
