How are bad valves and piston rings related?
Although bad valves and piston rings have similar symptoms; the time and costs of repairing them are quite different. Valve problems are a sign of serious issues with your engine. The intake and exhaust valves rely on physical contact with the valve seat and guide for cooling.
Why do you need a piston ring on a cylinder?
These high temperatures can cause serious damage. A piston ring helps transfer this excess heat from the piston head to the cylinder, reducing the risk of heat damage. Lubrication Control: A film of oil is necessary to keep the piston lubricated. The piston ring helps regulate the amount of oil that reaches the piston.
How are compression seals and piston rings related?
Compression Seal: The ring creates a seal, preventing combustion gasses from leaking out of the chamber. Leaks can drastically reduce engine performance. Heat Transfer: Every time combustion occurs, the internal temperature of the chamber spikes. These high temperatures can cause serious damage.
What does oil pour out of PCV valve mean?
If you hear it whistle out of the PCV valve, oil pour hole or dipstick is a sign of that air getting past the piston rings – i.e. cooked rings. And if any air bubbles out through the coolant, it indicates a head gasket leak. A compression test will show whether its the seals or the rings.
How are piston rings related to oil consumption?
To better understand ring-related oil consumption, let’s look at piston and piston ring design. For example, many top rings are flat with a convex or barrel-shaped outer edge that contains a molybdenum inlay. The moly inlay retains oil and is resistant to high combustion temperatures.
What happens when the piston rings get worn out?
The engine inside of your vehicle contains a series of rings that are called piston rings. These rings help regulate the oil pressure and the amount of oil consumed by the engine. If the piston rings were to get damaged or worn out, then you will have all kinds of problems happening with your engine.

What does it mean when your oil control ring is worn?
Photo 3: As seen in this photo, a collapsed oil control ring expander and worn oil control rings are indicated when the oil control ring assembly is flush with the piston ring land. To help meet emissions standards, manufacturers have reduced piston-to-cylinder clearances.
Where are the piston rings located in an engine?
Healthy engines should have compression over 100 psi per cylinder; with no more than 10 percent variation between the highest and lowest readings. Piston rings are located between the piston and cylinder and provide four different functions:
What happens to the piston during an intake stroke?
During the exhaust stroke, the piston will begin to head upward again; pushing the expended mixture through the now open exhaust valve. After the exhaust gases have escaped the cylinder; the exhaust valve will close and the intake stroke will occur again. The symptoms of bad valves and piston rings are quite similar.
When do you know you have bad piston rings?
If there is a lot of exhaust smoke coming out of your vehicle, this could be an easy sign that you have bad piston rings. This smoke will look very thick and have gray and white colors to it. When you have bad piston rings, engine oil will start leaking into the combustion chamber.
Is the RK top end gasket part of the piston kit?
NOTE: RKT Top end gasket kit is comprised of the Base Gasket, Y -Pipe Gasket, Exhaust Valve Gaskets (Non-HO ONLY), and Inner Compression O-rings. These gaskets are not part of the piston ONLY kit but are available in the options. NOTE: This will address the issues associated with the OEM pistons!

What are the gaskets on a Polaris piston?
NOTE: ALL pistons come with Rings, Wrist Pin, and Circlips! NOTE: RKT Top end gasket kit is comprised of the Base Gasket, Y -Pipe Gasket, Exhaust Valve Gaskets (Non-HO ONLY), and Inner Compression O-rings. These gaskets are not part of the piston ONLY kit but are available in the options.
How are piston rings replaced in a car?
Replacement Cost. Since the piston rings are inside of your engine, this means an auto mechanic will need to remove the engine from your vehicle and disassemble it so they can access the worn-out piston rings. After they replace the piston rings, they must reassemble the engine and install it back into your vehicle.
