Valve train problems are commonly found in automobiles and other motor vehicles, particularly in high-mileage cars and those without regular maintenance. Suppose you’re experiencing issues with your valve train. In that case, you should know that this can be a costly repair to make, so it’s essential to get the problem diagnosed and treated as soon as possible. Fortunately, there are several telltale signs of potential valve train problems. You can save time and money by knowing what to look out for! Here are some common symptoms of valve train problems you should watch for.
What is a Valve Train, and What Does it do?
The engine valve train is a series of components responsible for opening and closing the intake and exhaust valves. Several components comprise the valve train, including the camshaft, cam lobes, cam follower, rocker arms, and push rods. The valve train is controlled by the rotation of the camshaft, which is connected to the timing belt in most engines. While the valve train has several potential points of failure, these components are typically reliable unless poorly maintained.
Signs of Valve Train Failure
Several telltale signs of valve train problems can alert you of potential issues before severe damage is done to your car’s engine. One of the most common signs of valve train problems is blue smoke coming from your car’s tailpipe. This typically occurs from worn valve stems that allow oil to seep into the combustion chamber. In addition, valve train failure can cause rough idling, misfiring cylinders, unusual noises, and combustion pressure leaks from one of the valves being stuck open due to carbon deposits. Also, cars run with old and contaminated oil or run with low oil levels are more likely to have valve train problems.
What to do About Valve Train Problems
Suppose you notice any of the signs of valve train failure. In that case, it is essential to consult your mechanic to have it diagnosed and repaired. Typically, your mechanic can fix valve train problems before causing severe engine damage if caught early enough. While poor maintenance can be a factor that makes valve train failure more likely, older cars with high mileage may also show signs of valve train failure due to wear and tear.
If you notice the signs of valve train failure, don’t ignore it; instead, see your car care specialist immediately before your valve train problem becomes more significant.
