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.

How much does it cost to replace piston rings on a GM Truck?

Someone on Car Talk said they were quoted $2,300 to replace the piston rings, resurface the valves and replace the valve seals. A member on GM-Trucks.com said his service advisor at a local dealership quoted him $3,500 to replace the piston rings in his truck.

What causes oil to come out of the piston?

Piston rings eventually start to wear and the seal between the piston and cylinder is no longer air tight. As a result, oil makes its way from the crankcase past the piston and into the firing chamber. Symptoms of this are white smoke coming from the tailpipe and a drop in engine oil level.

How much does it cost to replace Pistons?

The cost to replace piston rings can depend on a number of factors. This can include the make and model of a car, the type of engine, and the condition of the engine. On average, a mechanic can charge anywhere from $1,800 to as much as $3,500+ to replace a worn out piston ring/s.

What are the signs of a worn piston ring?

The most common sign is oil consumption and excessive white smoke in the exhaust, especially when the engine is cold. This is normally a sign of worn piston rings. More extreme signs could be metal shavings in the engine oil (a common sign of dangerously worn bearings) and “knocking” or “chattering” from the engine bearings.

What causes oil to stick to the piston ring?

If deposits in the piston-ring lands cause the rings to stick, oil can migrate into the combustion chamber, where it burns. This not only leads to harmful deposits, it also increases exhaust emissions as the burned oil exits the tailpipe.

Why do I need bigger injectors on my Silverado Sierra?

Putting in bigger injectors is only useful if you have a fuel system that can provide adequate flow. Using that much fuel is only great if you have pistons,rings etc. that can take all the extra heat generated. Pumping in that much fuel is only useful if your air flow can keep up (that includes flow in AND out).

How can I get more power out of my Silverado Sierra?

You can accomplish this by changing your gears, changing your tires, swapping trannies, or going all the way and getting a cam/crank setup that is built for low end power. Just don’t be suprised when your top end suffers dearly for this.
