How Long Can You Drive With A Bad Rocker Arm

If you’ve ever had a car that needed repairs, you know the feeling of dread that comes along with it. No one wants to spend money on car repairs, but unfortunately, it’s often a necessary evil. One of the most common car repairs is a bad rocker arm. But how long can you actually drive with a bad rocker arm? The answer may surprise you. In this blog post, we’ll explore the answer to this question and give you some tips on what to do if you find yourself in this situation.

What is a rocker arm?

A rocker arm is a lever that transfers the motion of the camshaft to the valves in an engine. It consists of a shaft with a roller at one end and a pivot at the other. The roller end sits on top of the valve stem, and the pivot end is connected to a pushrod. As the camshaft turns, it pushes on the roller and causes the rocker arm to rotate about the pivot. This in turn opens or closes the valve.

Rocker arms can wear out over time, causing problems with engine performance. If a rocker arm breaks, it can cause severe engine damage.

What causes a rocker arm to go bad?

A rocker arm is a key component in the valvetrain of an internal combustion engine, and it helps to transfer motion from the camshaft to the valves. Over time and with extended use, the rocker arm can begin to wear down, which can cause a number of problems.

The most common symptom of a bad rocker arm is a ticking noise coming from the engine. This is caused by the worn-down rocker arm not making proper contact with the valve, which can lead to reduced engine performance. Other symptoms can include oil leaks, as well as engine misfires and power loss.

If you suspect that your rocker arm may be going bad, it’s important to have it checked out by a mechanic as soon as possible. Depending on the extent of the damage, they may recommend replacing the entire rocker arm assembly or just individual parts. In either case, getting these repairs done in a timely manner is crucial to maintaining your engine’s performance and preventing further damage down the road.

How long can you drive with a bad rocker arm?

If your car has a bad rocker arm, you may be wondering how long you can continue to drive it. The answer depends on a few factors, including the severity of the problem and the make and model of your car.

If you have a bad rocker arm, it means that one of the parts that helps connect the camshaft to the pushrods is not working properly. This can cause a number of problems, including decreased engine power, increased fuel consumption, and engine misfires.

If the problem is severe, it can cause the engine to stall or shut off completely. In this case, it is best to have the car towed to a mechanic so that they can fix the problem.

However, if the problem is not severe, you may be able to continue driving for a while. Just be sure to keep an eye on your engine’s performance and be prepared to take it to a mechanic if necessary.

How to tell if your rocker arm is going bad

If you’re unsure whether or not your rocker arm is going bad, there are a few things you can look out for. First, check for any unusual noises coming from the engine area. A clicking or tapping noise may indicate that the rocker arm is loose and needs to be tightened. Also, look for any oil leaks coming from the rocker arm area. If oil is leaking, it may be seeping into the engine and causing damage. Finally, check the engine’s performance. If it’s running rough or misfiring, this could be a sign that the rocker arm is damaged and needs to be replaced.

How to fix a bad rocker arm

If you have a bad rocker arm, there are a few things you can do to fix it. First, you will need to remove the old rocker arm. This can be done by unscrewing the bolts that hold it in place. Next, you will need to install the new rocker arm. Be sure to use new bolts when doing this. Finally, you will need to adjust the rocker arm so that it is in the correct position.


If you’re driving with a bad rocker arm, it’s important to be aware of the risks and take steps to avoid them. Driving with a bad rocker arm can cause engine damage, loss of power, and decreased fuel economy. It’s best to have your rocker arm checked by a mechanic as soon as possible so that they can fix the problem before it causes any further damage.
