 What Happens If the Valve Stem Seals Fail?

When the valve stem seals of an internal combustion engine fail, it can lead to a variety of issues. Oil consumption is one of the most prevalent symptoms. The engine may burn oil excessively or leak oil into the combustion chamber, resulting in higher pollutants and decreased fuel economy.

Additional signs of faulty valve stem seals include:

Power and performance have been reduced.

If the seals do not seal properly, too much or too little air and fuel might enter the combustion chamber, affecting engine performance.

 

Rough idle

If the seals are not sealing properly, the engine may run poorly or vibrate at idle.

The scent of burning oil

If the seals let oil to escape into the combustion chamber, it might generate a burning oil odour.

Exhaust fumes

A defective valve stem seal can allow oil to burn in the combustion chamber, resulting in white or blue smoke discharged from the exhaust.

Oil usage

If the valve stem seals allow oil to flow into the combustion chamber, it might result in higher oil consumption.

Oil seeps

If the valve stem seals are worn or cracked, oil might seep from the engine.

If you believe that the valve stem seals on your car are faulty, you should get the problem checked and fixed by a trained technician as soon as possible. Ignoring the problem might lead to more significant problems, such as engine damage, which can be costly to repair.
