The truth is, the prices can vary depending on how complicated your vehicle’s situation may be. In this blog post, you will find out everything you need to know about getting your car fixed and what it costs to do so!

What Is Rod Knock?

Rod knock is a result of the piston rod wearing down until it scrapes against the cylinder wall. The noise from this scraping sound can be heard when you are driving and accelerating or while your car is idling. This may not seem like an urgent problem to fix, but in reality, it could lead to major engine problems that will cost more money than you think!

What Are the Signs of Rod Knock?

  • engine running rough or hesitating during acceleration and in between gears while driving
  • excessive smoke coming from under the car’s hood
  • engine misfires under acceleration and while cruising at highway speeds.
  • Engine knock when starting out in the morning; this will go away once the engine has warmed up.
  • A rough or jerky driving experience
  • Engine knocking sound when you accelerate, idle, and release gas pedal at a stop sign. You might also hear this noise while accelerating to highway speeds.
  • Increase in engine oil levels and consumption.
  • Major risk for expensive repairs if not addressed early on!

The cost of repairing rod knock will vary depending on the severity of the problem and how quickly it is addressed. However, the average cost for a tune-up only ranges between $75-$150, whereas a full engine replacement can be upwards of around $4000!

How Much Does It Cost To Fix A Rod Knock

How you choose to handle this issue really depends on what your budget may be. So if you are wondering how much does it cost to fix a rod knock, then take time to consider before moving forward with any repairs! Here is some costing of repair parts that you need to consider before estimating an average cost to fix rod knock.

Costing of New pistons:

The cost of new pistons would depend on the type. For example, you can buy a set of high-performance forged pistons for about $1000, and it will take care of any rod knock problems as well as some other engine issues that may pop up later down the road! You do not have to purchase this expensive set all at once, though. You could always save them for when your car needs them in the future, which would help improve performance even further.

One way to tell if something wrong with piston rings is via oil levels or by listening closely after startup and driving time. If you know what’s going on, then you can address it while still being able to get back into your normal routine ASAP rather than waiting for something to happen.

Costing of Connecting rods:

The cost of connecting rods will vary depending on the mileage and make. You can take your car into an auto service shop for help in this situation, or you could also look online at places like RockAuto so that you know what is available and how much it would cost before heading out there yourself! This way, if they cannot fix the problem, you are going with something that isn’t too expensive but still does the trick.

It’s always better to have some type of idea about timing as well when it comes down to what we’re talking about right now because otherwise, things may end up taking longer than necessary due to confusion which will only lead up costing more money! Again, this is something that you and the mechanic will need to talk about, but it’s not going to be a “pricey” conversation, in general.

Costing of Camshaft bearings:

The Camshaft bearings are going to need some type of replacement at this point due to the fact that it’s been broken for a while. So the only variable you have here is whether or not the mechanic will charge by the hour or what-have-you so be sure to go over all those types of details before heading in!

You do want to make sure that there aren’t any more surprises along the way because if they find another problem during their time with your vehicle, then you’re looking at an even higher price. This can happen when something else has gone wrong and isn’t related, but it takes up valuable time, which would cost more money as well!

Costing of Timing Belt and Tensioner:

The timing belt and tensioner cost will vary from car make, model, year – so it’s hard to say for sure what your particular vehicle might be. However, you can consult with a mechanic near you or do some research online first.

Another thing that will affect this price point is how long they have been broken in terms of hours. If there are 100k miles on the engine, then something has likely gone wrong by now! On average, these parts should last around 60-75K before any issues start happening but again, very dependant on the mileage and age of the car as well!

Costing of Valve Cover Gasket:

The cost of a valve cover gasket can vary depending on the vehicle, but it is usually between $250-$400. How much does that include? In most cases, you are paying for just the part and not labor hours.

However, if your car requires less than about 30-minutes worth of labor to replace then, this would be factored in as well. For example, the average amount someone spends when they get their valves replaced is around $600-$800, which includes both parts and labor costs.

Costing of New Crankshaft:

If the engine needs a new crankshaft, then you need to pay a good amount of cost. Crank shafts are not cheap, so you have to understand that this is an expensive investment for your car’s health and safety. The average price of a new crank shaft ranges from $580 – $700 on Amazon.

You should factor in the labor costs as well when considering what type of repairs need to be done or how much money you want to invest into your vehicle because those can range from around $500-$2000 depending on where you go (parts & labor). So if you’re looking at the total cost, just be prepared with knowledge about what kind of service work will be needed to fix your car.

Frequently Asked Questions

How Long Will an Engine Last With Rod Knock?

However, if the knocking persists even after removing pressure from that cylinder, it could mean something more serious like worn valve guides, in which case you’ll need to replace all four pistons for at least $1200 – $2000 depending on what type of vehicle (car/truck) you have.

What Does a Knocking Rod Sound Like?

Knocking rods sound like a loud tapping or clicking noise coming from the engine. You’ll also feel vibrations in your car if you’re driving when it’s happening, and there might be an oily substance dripping down onto your driveway too.

How Does Rod Knock Cause Engine Damage?

The knocking rod is usually made of two separate parts that are fastened together and connected to the crankshaft. When a knocking rod starts hitting against its connecting pin, it can cause damage in three ways – wearing down the metal pieces as they rub up against each other; building up deposits from carbon or dirt on both surfaces, and causing wear within the bearing pins where you’ll often find cracks forming over time


If you’re looking to save money, it’s important that your rod knock problem is fixed as soon as possible. Then when you want to fix the problem, there’s come the question of how much does it cost to fix a rod knock. The cost of repairing a rod knock can vary depending on the severity and location of the damage. However, in most cases, it will be cheaper than replacing an engine block. 

There are two ways that you can go about fixing it. First, replace or straighten out the bent metal rods in your engine block with new ones, or by replacing the cylinder head gasket, which will also require work from a mechanic who knows how to do this type of repair job without damaging other parts of your car’s engine system.

If you’re still unsure about the answer to this question, it’s time for a visit to your mechanic. A quick chat might save you some money in the long run!
