Grinding noise on cold engine start up

Hello! So I know that the Honda CR-V's have had issues with the VCT. My car grinds in the AM only during cold morning startups. So you guys said that the VCT is a type of VVT. If I schedule an appointment for a VVT replacement they will be replacing the VCT? Sorry that I'm not familiar with this!
My car has an automatic transmission.

So, what is that grinding noise you hear when starting a car? Most likely, if it is true grinding that you hear, the problem is related to the starter. Causes include the starter not lining up correctly with the ring gear on the flywheel, missing or damaged gear teeth, or a faulty solenoid.
Excessive Pad Wear: The single most common reason to hear a grinding noise when braking is excessive pad wear. Once the material has been worn off the backing plate, you`ll be experiencing “metal on metal”. Part of the brake caliper could also be touching the rotor at this point.
Symptoms of a Failing VTC Actuator

Engine Misfire: When the VTC actuator fails, the engine may misfire. This is because the valve timing is no longer optimized, which can cause a loss of power and performance. Rough Idle: A failing VTC actuator can also cause the engine to idle roughly or erratically.

The possible cause could be the variable valve timing control (VTC) actuator is defective. Replace the VTC actuator. This procedure does not require the complete removal of the cam chain and associated parts, so repair time is shorter.
A common cause of grinding noises under your car are failing wheel or hub bearings. Wheel bearings allow the wheel and tire to rotate and are designed for low friction, while hub assemblies have an additional responsibility of securing the wheel and tire to the vehicle.
The most common causes of grinding noises in automobiles are worn-out brakes, a faulty CV joint, or transmission issues. It`s important to note that, whichever component is causing the grinding noise, it needs immediate repair. The following are common causes of grinding noise in automobiles.
If you notice your car making a grinding sound when it accelerates, your issue is likely to do with your transmission, a problem with your differential, a bad wheel bearing, a damaged CV joint, or a worn engine/motor mount.
You might notice a grinding noise when driving at low speeds. The most common causes are problems with your continual velocity joints, brake pads, wheel bearings or alternator. Examining each one of these parts can help you pinpoint exactly where the issue is.
A faulty VVT solenoid can prevent the VVT actuator from getting the oil pressure it needs. When this happens, you may hear a rattling noise or ticking noise from the engine. Some automakers (e.g. Ford) have technical service bulletins (TSBs) for this concern.
The sound can either be from a hydraulic valve lifter, or piston-to-cylinder wall clearance. As the engine warms, the clearances change and get tighter and noises will usually disappear. The use of full-synthetic engine oil can in some cases quiet the cold start up engine noises.
A loud rattle type noise may be noted from the engine after a cold start. This can be caused by a faulty valve timing control actuator. Replacing the failed actuator will commonly correct this noise issue.
Cold weather can exacerbate underlying car problems, so you may begin to hear squeaks, squeals and other funny noises you haven`t heard before. These noises may be caused by the engine belt, the serpentine belt, the air conditioning compressor or a power steering pump.
Most of the time, if you hear scraping and grinding, it can be attributed to one of two main issues: Worn-out brake linings. Worn-out wheel/hub bearings.
If you notice your car making a grinding sound when it accelerates, your issue is likely to do with your transmission, a problem with your differential, a bad wheel bearing, a damaged CV joint, or a worn engine/motor mount.
If you`re hearing grinding noises when turning, you should also check the condition of your wheel bearings. Wheel bearings are situated between the axle and the wheel, and minimize friction, allowing for smooth movement while driving.
Driving with grinding brakes is simply not safe. Brakes are a critical component of safe driving and should not be overlooked. If your brakes start to fail: Don`t drive any further.
You`ll know when you have a wheel bearing going bad by a growling noise that is similar to very loud tire noise. It will get louder as you go faster, and may even wind down to a grinding sound if you`re moving slow enough.
Worn Seals or Gaskets: The exhaust system has quite a few seals and gaskets and if they are failing it can cause the engine to run louder, and sputter at times. Over time, gaskets and seals will wear down and eventually have to be replaced.
The most common reasons a Honda Civic has a rattling noise are the ball joints, struts or strut mount, or a problem with the sway bar links. Search our network of RepairPal Certified shops near you to speak with a technician about your issue. Oops!
VTC is a hydraulically operated system that controls the timing of the chain-driven intake camshaft, advancing or retarding it during the intake cycle.
Grinding sounds from engine or transmission may indicate a bearing failure somewhere and requires immediate shut-down and troubleshooting. Similarly wheel bearings that are anything less than smooth and quiet may be in need of attention.

the most relevant questions and answers related to your specific issue

Engine tapping noise related to short term fuel trim but only on cold start up.
ANSWER : Has a mechanic’s stethoscope been used to track down the specific location of the noise? There are several solenoid valves in the engine bay that do not run all the time and may be pretty loud once they start, such as an evaporative emissions purge valve and the like. The high fuel trims on one bank sound like you may have a problem on one side with a vacuum leak. A positive trim means air is being added and the computer is trying to add fuel to compensate.

I recommend having an experienced technician, such as one from YourMechanic, come to your location to determine why the engine is making a noise and suggest the proper repair.

Turned on back winow heater and engine made a noise …when lights are turned on engine makes a noise like it can’t take load ….
ANSWER : Hi there. It appears you have more than one problem with your vehicle. The noise coming from engine area with a load on the electrical system, may be a bad diode in the alternator. Continuing to drive the vehicle with a bad alternator diode, may leave you with a dead battery. The hot air coming from the vents sounds like blend door actuator(s) problems. I recommend the concerns your vehicle has, it be inspected by a certified technician like one from YourMechanic to pinpoint the noise and help you fix it accordingly.

Fuel pump engages. Batery good, alternator good volts, jump start helps when wont start. Temp does not matter. Intermittent?
ANSWER : Hello. Thank you for writing in. There are several reasons your vehicle may only start when jump starting. The first and most common is a build up of resistance that is causing you to need a boost of voltage to get the engine started. This may be due to poor battery cables, a bad ground connection, a poor starter solenoid, and a couple of other issues. The first thing you want to do is perform a visual inspection of the starting system. Make sure there is no corrosion build up in the battery cables. You can also check the resistance across these wires and make sure you have a solid connection between components. You then want to make sure the starter solenoid is doing its job. It is responsible for taking the small amount of electricity sent by the ignition and turning it into a huge electrical charge that is strong enough to push over the engine with the help of some gear ratios in its favor. Do some more testing, and stick to the basics before assuming its something seriously complicated.

Grinding noise when starting engine.
ANSWER : Hi there:

Improper alignment or installation of the starter can cause this grinding noise to occur. However, it’s also possible that internal components inside the starter, the starter relay or the flywheel teeth could also be the source. It’s really difficult to diagnose a noise without physically being there to inspect the vehicle on site, so you should have a mobile mechanic complete a car is making a noise inspection, so they can pinpoint the issue and recommend the right repairs.

Issue with Mazda 626, starts up then makes a grinding noise while in park
ANSWER : Your symptoms suggest that the starter solenoid contacts are burned enough to stick in the "Start" position (engaging the starter drive and motor), even when the ignition switch is not energizing the relay portion of the starter solenoid. The starter motor continues to run after the motor starts, causing the horrible grinding. Eventually, the engine speed kicks the start drive back enough to jar the contacts loose, and things are fine – until the next time the solenoid contacts stick. Replace the starter solenoid – usually packaged as a starter assembly.

I would recommend having the starter replacement job completed by a mobile, professional mechanic, such as one from YourMechanic, who can assist you at your home.

Check engine on knocking engine milky cap but not in oil change loud knocking noise while driving and cold start up
ANSWER : Coolant leaks can be external or internal. If the coolant is leaking internally into the cylinders or crankcase, that will require a fairly significant repair. If the coolant is leaking externally, unless the leak is at the head gasket or the lower intake manifold, external leaks can be repaired readily. On the engine you have it was really common to have coolant leaks at the lower intake manifold, so common that the gasket there was completely designed and a different repair procedure was specified (higher torque on the manifold studs). To get the coolant leak diagnosed, please use YourMechanic’s coolant leak diagnostic service link. The knocking noise is obviously of concern. Unfortunately, typically, such noise is from worn bearings, connecting rods, and other major components. The noise might be accompanied by low oil pressure. My best advice is have the cooling leak diagnosed in case that is readily resolvable. The mechanic can evaluate the noise and if it is internal the engine will eventually have to be disassembled and rebuilt. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.

My car isn’t starting, it’s really cold out. I was wondering how can I start it with this cold weather
ANSWER : Hi there. Given the description of not being able to start your vehicle, when it is cold and jump starting the vehicle without any problem. This leads me to believe the battery does not have enough cold cranking amp capacity. The engine needs to turn over fast enough to start. This may be nothing more than a weak battery. I recommend having this confirmed by a certified technician from YourMechanic.
