Car Makes Noise When Starting Then Goes Away?
If you’re hearing a car noise when starting up that goes away after a few minutes, it’s likely nothing to worry about. However, if the noise persists or gets worse, you’ll want to take your car in for servicing. In this blog post, we’ll go over the possible causes of this type of car noise and what you can do about it. Stay safe on the roads!
What’s that Rattling Sound Coming From your Engine?
Have you ever been driving along and heard a strange rattling sound coming from your engine? If so, it’s important to get it checked out as soon as possible, as it could be an indication of a serious problem. One possibility is that the noise is being caused by a loose heat shield.
The heat shield is there to protect other components from the heat generated by the engine, and if it’s not secure, it can start to rattle. Another possibility is that the noise is coming from a loose exhaust manifold. The exhaust manifold collects exhaust gasses from the cylinders and routes them out of the engine, and if it’s not secured properly, it can also start to rattle. In either case, it’s important to have a qualified mechanic take a look at your vehicle as soon as possible to diagnose the problem and make the necessary repairs.
How Does a Car Starter Work?
The car starter is one of the most important components of your vehicle, and it’s responsible for getting the engine going when you turn the key in the ignition. The starter is basically an electric motor that uses a small amount of power from the battery to spin a larger gear. This larger gear then meshes with the teeth on the flywheel, which is attached to the engine. As the flywheel starts to spin, it sets the engine in motion and gets it running.
If you’re having problems with your car starter, it could be due to a number of different issues. One possibility is that the starter motor itself is going bad and needs to be replaced. Another possibility is that there’s a problem with the electrical connection between the starter and the battery. Or, it could be that the flywheel is damaged and needs to be replaced. In any case, it’s best to have a qualified mechanic take a look at your vehicle to diagnose the problem and make the necessary repairs.
When did you First Start Noticing the Noise in your Car when Starting It Up?
I first noticed the noise in my car when starting it up about a month ago. The noise is a rattling sound that comes from the engine area. It only lasts for a few minutes and then goes away. However, I’m concerned that it could be an indication of a serious problem. I’m going to take my car in for servicing so that a qualified mechanic can take a look at it.
5 Reasons Why A Car Engine Knocks On Startup Then Goes Away:
Sticky Lifters:
Most car engines will knock or ping at some time or another, particularly when they’re under load. However, if your engine is knocking on startup and then goes away, it could be due to sticky lifters. Lifter is the term used to describe the moving parts of the valve train that open and close the intake and exhaust valves. Over time, these lifters can become gummed up with oil and varnish, causing them to stick in the down position.
When this happens, the engine will make a knocking noise on startup that goes away as the lifters free up and begin moving again. If you notice this happening, it’s important to have your car checked out by a mechanic as soon as possible. Sticky lifters can eventually lead to engine damage if they’re not fixed.
Piston Slapped:
One common reason a car engine knocks is due to a condition called piston slap. When this happens, the pistons in the engine are not properly lubricated, causing them to make a knocking noise when the engine is first started up. Once the engine warms up and the oil starts flowing, the noise should go away. However, if the oil level is low or the oil pressure is low, piston slap can become a persistent problem.
Oil Drain-Back :
One potential reason why a car engine knocks on startup then goes away is due to oil drain-back. When the engine is off, oil drains back from the top of the engine down into the oil pan. If there is not enough oil in the pan when the engine is started, it can cause a knocking sound. The noise should go away once the oil has had a chance to circulate back to the top of the engine.
Worn Components:
Another potential reason for a car engine knocking is due to worn components. Over time, the moving parts in the engine can start to wear out, causing them to make noise. In particular, worn piston rings or bearings can cause a knocking noise on startup that goes away when the engine warms up. If you notice this happening, it’s important to have your car checked out by a mechanic to see if any repairs are needed.
Worn-out Drive Belt :
If you have an older car with a belt-driven engine, it’s possible that the noise you’re hearing is due to a worn-out drive belt. The drive belt is what turns the engine’s accessories, such as the water pump, alternator, and power steering pump. When the belt gets old and worn out, it can start to slip and make noise. If you think this might be the problem, it’s easy to check by opening the hood and inspecting the belt. If it looks worn or damaged, it will need to be replaced.
How To Do If Your Car Makes Noise When Starting Then Goes Away?
If your car makes noise when starting then goes away, there are a few potential causes. It could be due to sticky lifters, piston slap, oil drain-back, worn components, or a worn-out drive belt. If you’re not sure what’s causing the problem, it’s best to have your car checked out by a mechanic. They will be able to diagnose the problem and recommend the best course of action.
What Are The Causes Of Rattling Noises In Your Car’s Engine?
Rattling noises in your car’s engine can be caused by a number of different things. It could be due to loose parts, worn-out components, or something as simple as debris caught in the engine.

5. Screeching or Growling When you Step on the Brake Pedal:
Screeching or growling when you step on the brake pedal is usually a sign that your brake pads are getting low and need to be replaced. If the noise is accompanied by a vibration, it could also be a sign of warped rotors. Either way, it’s important to have the problem checked out by a qualified mechanic as soon as possible. Continuing to drive with worn-out brake pads can damage your rotors and lead to more costly repairs down the road.
6. Loud Bang from the Rear of The Car:
If you’re driving along and suddenly hear a loud bang from the rear of your car, it could be an indication that something is seriously wrong.

In any case, it’s best to get the car checked out by a mechanic as soon as possible to avoid further damage.
8. Knocking or Pinging from Under the Hood:
Your car engine should run smoothly without making any strange noises. If you start to hear a knocking or pinging sound, it could be an indication that your engine is experiencing a problem. The knock could be caused by a build-up of carbon deposits on the valves, pistons, or other parts of the engine.
Alternatively, it could be caused by an issue with the oil pressure or timing belt. If you hear this type of noise, it’s best to take your car to a mechanic for a check-up. Otherwise, you could end up causing major damage to your engine.
9. Sounds Like an Off-Kilter Washing Machine:
If your car starts making a noise that sounds like an off-kilter washing machine, it could be a sign that your engine is having difficulty cooling itself.
