How Much Does it Cost to Replace Piston Rings
The piston ring is a split type ring that fits outside the diameter of a piston inside the engine. The main function of a piston ring is to help seal the combustion chamber, support a heat transfer from the piston to the engine, and regulate the engine’s oil consumption. As time goes on, the piston ring can often wear out, needing to be replaced. If this is the case, a mechanic will often need to be called in order to resolve the problem.
How much is it?
- The cost to replace piston rings can depend upon 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.
- For those that want to complete the job themselves, piston rings will come in a complete set often costing $79 to as much as $500. For example, the Mahle Piston Ring Set retails for $110 to $150.
- On the forum thread on the website ModdedMustangs.com, a user claimed that it will cost around $1,500 to disassemble the motor, around $500 to pull out the piston heads, and another $700 or so to tear down the motor and rebuild it.
What are the extra costs?
- The piston rings can be just a part of the problem. A mechanic may also recommend that other parts of the engine be replaced. There could be times where the mechanic will just outright recommend a new engine altogether.
What is going to be included?
- Replacing the piston rings can be a rather complex process. The mechanic is going to have to completely disassemble the car’s engine, recondition the car’s cylinders, and then reassemble all the parts. This is a very labor intensive project, often taking many hours to completely solve the problem.
Tips to know:
- Replacing piston rings is not ideal for amateurs. It is often best to leave it up to the professionals since more often than not, messing with the engine can often lead to more problems in the future.
- A common mistake for many car owners is that they think that the piston heads are the root of the problem. To get a proper diagnosis, you need to take your car into a local mechanic to check it out. You can often find that there other parts of the engine that may be causing problems such as an oil leak, etc.
How can I save money?
- Talk with a mechanic before replacing the piston heads. More often than not, some may recommend that you replace the entire motor rather than just the piston heads. This can be a cheaper alternative.
- If you are going to hire a mechanic, try getting a few quotes over the phone. Simply tell them the make and model of your car, the condition of the engine, and what process needs to be done. While some may want to see it in person, many will be happy to give you a ballpark estimate over the phone.
