well wen piston rings go u will have to change them to be safe i would change the rods and valves to,just to be on the safe side.

Answer:The engine will loose power, increase fuel use, increase pollution creation and use oil faster than normal.

As the problem progresses the engine will become hard to start and blue smoke will come from the exhaust.

Inside the engine the failing rings will allow more combustion products into the crank case causing the oil to loose effectiveness faster and speeding wear on other components.

How do you know if the piston rings in your car are bad?

Worn piston rings will cause your car to burn oil. It will smoke, and you'll have to add oil frequently. Additionally, the performance will fall off as compression is lost past the worn rings. There may be a "slapping" sound as the piston skirts slap the cylinder walls, and this will occur in cases of advanced ring wear.
