The valve is the engine’s best friend and ensures that the engine’s performance is top-notch; you have to schedule valve adjustment periodically. The valves play a pivotal role in the performance of the engine by opening and closing the entrance and exit to the premise of combustion cylinders. Let’s talk about when you should schedule valve adjustment and what the signs are.
In a poorly adjusted valve, it’s common for wear and tear to happen on the entire valve train. If the valves have excessive clearance, then it might cause damage or even failure of the camshaft lobes, rocker arms, or the valves themselves.
If you notice your vehicle consuming more fuel in an average ride, then you should get the valve adjustment done. The valves could have a combination of loose and tight valves on a cylinder. In such cases, it might result in the opening of the exhaust valve while the intake valve is allowing the fuel and air into the cylinder. The fuel and air mixture could go through the cylinder and out the exhaust.
Pre-ignition is one thing that might occur in an engine that needs urgent valve adjustment. Pre-ignition is a condition that occurs when the fuel in the combustion chamber is ignited before the spark plug fires. This condition might occur when the engine produces excessive heat, and the valve clearance is reduced. You should schedule a valve adjustment as soon as you see any signs of pre-ignition to avoid further damage.
Overheating of the engine is the most common sign of poor valve adjustment. The overheating might occur due to the little clearance of valves which might result in them taking more than average time to open and close. If you see any signs of overheating in the engine, then you should opt for an immediate valve inspection.
