The symptoms of bad valve seals and bad piston rings are quite similar. Any time either one of them fails the performance of the vehicle will be reduced along with other bad symptoms that are noticeable. If you notice thick smoke that’s a gray or white colour, this indicates that your car is burning oil if the piston rings are worn out and the valve seal is broken, this will be what allows oil to flow into the combustion chamber. Although bad valve seals and piston rings have similar symptoms, the time and costs of repairing them are quite different. However, if you are facing any issue with piston rings and valve seals of your car then you can visit us at PARTSAVATAR, CANADA

1. Function of Piston Rings and Valve Seals in a vehicle
Functions of piston rings in car engine are:
1. Sealing the combustion chamber so that there is minimal loss of gases to the crank case
2. Improving heat transfer from the piston to the cylinder wall
3. Regulating engine oil consumption by scraping oil from the cylinder walls back to the sump

2. Functions of Valve seals in car engine are:
A seal that fits around the valve stem and valve guide to prevent oil leakage. The more detailed
answer is:
A valve guide seal, also known as a valve stem seal or valve seal, is located on the engine cylinder
head inside of the valve springs. An automotive engine can have as few as 8 valves seals, or up to 32.
Symptoms of Bad Valve Seals and Piston Rings:
The symptoms of bad valve seals and bad piston rings are quite similar. Any time either one of them
fails; the performance of the vehicle will be reduced along with other bad symptoms that are
noticeable.
Exhaust Smoke: If you notice thick smoke that’s a gray or white colour, this indicates that your car is
burning oil. The only way this could happen is if the oil is leaking into the combustion chamber of
your engine.

3. Too Much Oil Being Consumed: If the piston rings are worn out and the valve seal is broken, this will
be what allows oil to flow into the combustion chamber.
Not Enough Accelerating Power: When there is damage to the piston rings and valve seals, the
compression will be reduced which causes you to lose power in your engine. As a result, you won’t
be able to accelerate when you put your foot on the gas pedal.
NOTE: Although bad valve seals and piston rings have similar symptoms, the time and costs of
repairing them are quite different. That is why you should educate yourself about where the
problem is coming from, whether it’s the valve seals or piston rings. Once you find out, you can
save time and money from having a mechanic figures it out for you.
If you regularly maintain your vehicle and get it serviced, then the damage to these components will
be minimal. Vehicles that are maintained poorly or have high mileage are prime candidates for
having damaged valve seals and piston rings.
