Tapping Noise when idling?
Hello,
my 06 Honda Civic has a tapping noise that can mainly be heard inside of the car. The tapping noise sounds as if something is loose, and it causes a vibration in the car. The noise begins only AFTER the car is warmed up (when the little squares are at the halfway mark in the tempt gauge). If the car is not warmed up, the noise does not start at all. My AC is NOT working- I was told that the compressor is broken. When I turn on the fan for the heat, the noise quiets down a bit. When I'm at idle and I turn the wheel, the noise stops for a few seconds, and then starts again. The noise

Experienced mechanics share their insights in answering this question :
Hi there. Check the engine mounts and see if they are loose, worn, or broken. Engine mounts that are not secure to the vehicle properly will make the vehicle vibrate when at a stop and in drive with the brakes on. The tapping noise could be the air conditioning fan cage tapping as it could be loose or simply change left over in your console. I recommend seeking out a professional, such as one from Your Mechanic, to help you diagnose your vibration while at stopped in gear with the brake on.
How to Identify and Fix Common car Problems ?

The most common reasons a Honda Civic engine makes a ticking noise are low oil level or pressure, an issue with the ignition system, or an exhaust leak.
The AC compressor can become worn over time, requiring replacement. The serpentine belt is connected to many of your car`s accessories, like the air conditioning, alternator, power steering pump, air pump, and more. This belt can become worn over time leading to poor tension and noises like rattling or squeaking.
Knocking sounds usually come from the condenser unit positioned outdoors and indicate that its crankshaft, piston pin, or one or more of its support springs or screws are unfastened or broken. Wear and tear can cause some parts to come loose and create a banging or rattling sound.
It is probably your AC compressor. If you search the forums for this you will find many threads regarding this and leaking freon. My civic had the same issue, it is a common issue with our car and Honda is giving us an extended warranty for this.
Engine Clicking (or Ticking) Sounds
The engine clicking sound can be caused by a leak in your engine, a faulty oil pump, or insufficient oil in the reservoir.
If your air conditioner is making rattling noises, it means that the parts are not working the way they should be. Leaving your AC with broken or damaged parts will likely lead to larger issues (and more repairs) in the future.
Ticking, rattling, clicking or rumbling: A loose piece of hardware could cause sounds like this to occur near the compressor. Hissing or screaming: A loud hissing or screaming noise from the compressor could indicate dangerous levels of pressure inside the unit.
The Compressor Fan Is Loose
If the knocking noise is coming from your AC compressor (the outdoor unit), the fan or one of its blades might be loose. This can cause the fan`s blades to bang into other parts of the compressor, creating a loud knocking noise.
The blower is the “fan” unit, and it`s usually located indoors. If it`s unbalanced it will create a banging or knocking noise as the fan spins. Other out-of-balance or loose parts. If the sound is more like a clanking, it could mean the compressor itself is loose, or parts inside the blower unit are hitting each other.
The most common reasons include a squealing fan motor, rattling exterior unit, rattling AC ducts, and faulty components such as failing condensing fans, blower fans, and compressors.
The majority of motors will have some degree of methodical ticking when they are running. The fuel injectors, purge valve, and PCV valve can all produce a ticking noise, but it will generally be quieter.
The most common cause of engine ticking noise is low oil pressure. This is an indication that vital engine components are not getting adequate lubrication. Your engine may be low on oil or there could be a problem inside the engine causing the low oil pressure.

Clicking noise in idle (link of Video of noise included)
ANSWER : Hi there. Although it is hard to pinpoint the exact source of this noise via a video, it sounds a lot like an exhaust leak. When the exhaust manifold of exhaust tubes age, they are exposed to elements, creating weakness in the metal and eventually will crack or break. It is also possible that this sound is caused by cylinder head hardware that is loose (such as lifters or rocker arms) or not getting enough lubrication. Again, without being there it is impossible to know for certain, but you might want to have a professional mechanic complete a car is making a noise inspection to determine what is causing this issue.

My cars makes a rhythmic tapping noise while idling and the noises accelerates and loud end when my rpms go up,
ANSWER : Without listening to the noise myself and going on what you describe then I would have to say it is an engine piston rod knocking inside the motor. You should have a mechanic like one from YourMechanic listen to the noise and see if the engine needs internal repairs.

High idling, jumping while idling, idle air control valve code
ANSWER : Hi there. This can be caused by the issues that you mentioned or a number of other things. You need to make sure all of the connectors are making good contact. I would then need to know what codes are in the computer to know if this is a circuit issue or not. Most of the time, it is not the circuit but instead a vacuum leak.
If there is a vacuum leak, then the vehicle will act like this and the computer cannot control the idle. Most of the time it is a bad hose or an EGR valve that is stuck open. That is the most common cause for this. I typically remove the EGR to check it to feel the diaphragm on the bottom of it to see if it is moving correctly. If you need to have this repaired, consider YourMechanic, as a certified mechanic can come to your home or office to diagnose and repair your car’s idling issue.

I’m hearing a clicking noise while the car idles in Drive, as the engine idles high.
ANSWER : You may be hearing a solenoid for the vapor purge control system. This would be normal if it is a ticking noise that sounds like a clock ticking only when you give it a little gas and goes away when you let off the gas.
If you think it is something other than this, then have a mechanic inspect the noise for a proper diagnosis.

Rattling noise upon starting and then louder rattling at idle if load is placed on engine such as A/C
ANSWER : Hi there. Given your mileage and your maintenance of the idler pulley, your problem is likely worn/weak hydraulic lifters (or other valve train wear) or the timing gear set. Starting the engine briefly (less than 30 seconds) without the serpentine belt attached, will eliminate noises from all accessories if the problem is with one of them. I would recommend having the engine inspected in person by a professional so that the rattling noise can be diagnosed and properly corrected.

I hear chirping from under the hood most prevalent while braking. The noise stops when the car is no longer moving.
ANSWER : Hello there. Thanks for the detailed description on your inquiry – it really helps us out. Based on what you have indicated, my first assumption would be that you have a loose serpentine / drive belt or a pulley that is showing early signs of wearing out. When the noise happens during breaking and normal operation, it tends to be caused by a belt that is frayed or loose. As you accelerate, the belt will tighten naturally; which is why the sound might slow down during idle. If the belt and pulley’s have not been replaced within 40,000 miles or so, it’s probably due to be completed. Since it’s possible that this could be from a different source, it’s also a good idea to have a professional mechanic complete a car is making a noise inspection to verify the source of this noise before making repairs.

Hear engine grinding noise at idle only-park or drive. Then goes away above idle. Not AC or any pumps. What is it?
ANSWER : Hi there. In many cases, the grinding noise coming from an engine at idle and in park can be caused by a VVT solenoid or switch. Typically solenoid problems are caused by dirty oil, which clogs the screen that sits between the solenoid and the VVT pressure switch. If the solenoid doesn’t operate, the VVT system will remain disengaged, which can adversely impact engine performance, fuel economy and more. To be certain however, it’s best to have a professional mechanic come to your home to complete an engine is making a noise inspection. This will allow them to diagnose this issue and provide an accurate repair.
