Exhaust Valve Problems
Inside a vehicles engine houses a myriad of intricately moving parts to propel the car forward. Parts, such as exhaust valves, play a key role in the functioning of the engines cylinder assemblies.
Function
Exhaust valves work inside the cylinder heads to function with the exhaust port, allowing fumes to leave the chamber. The valve itself runs extremely hot due to the lack of cooling from the hot exhaust fumes.
Identification
Exhaust valve problems arise more often than other valve problems because of the extreme heat, about 1200 to 1350 degrees Fahrenheit. Though it is made of strong alloy material, it can erode from burn-out, creating a hole in the side of the valve.
Considerations
Aside from being burned out, improper replacement of a valve can shorten its life. Additionally, excess deposits on the cylinder and valve can create a hotter environment to allow the erosion process to begin and hasten forward.
