When I first start my vehicle in the morning, I usually hear a "clicking" or "ticking" noise coming from the engine. I don't think I've heard this before in my older vehicles. Once the engine warms up, the noise seems to disappear. Is this something to be concerned about? What could cause the noise?
If you feel this is a concern then have a mechanic listen to the noise to see if it may be normal or not. Some newer vehicles have emission control devices that may make noise when first started and then go away till it is restarted again. A certified mobile mechanic from YourMechanic can inspect the source of the noise at your home or office.

Sometimes an engine will tick when it`s first starting due to a lack of lubrication on top of the motor. The ticking sound is commonly caused by opening and closing valves or rocking arms. This could mean the car is low on oil or there is a problem with the oil delivery system that needs to be repaired.
It might be a battery or alternator problem
Perhaps your battery`s dead, or your alternator, which charges the battery, isn`t working correctly. If the source of the clicking is electrical, the starter (a small motor energized by the battery that gets the engine running) doesn`t have enough juice to stay powered.
The most common reasons a Toyota Highlander engine makes a ticking noise are low oil level or pressure, an issue with the ignition system, or an exhaust leak.
An engine with low oil or low oil pressure can make a ticking noise due to a lack of lubrication. If you are low on oil, it may indicate either oil consumption or an oil leak, both of which should be addressed as soon as possible. If you have low oil pressure, you will likely get a warning on the dash.
A distinct clicking or ticking noise emanates from the high pressure fuel pump that can be very noisy during cold starts and quietens following engine warm-up. The sound is more noticeable when standing outside the vehicle, with the hood up, or when the vehicle is next to a building such as a drive-through.
Often, a lifter tick will be most prevalent as soon as you start the engine, and may get quieter or disappear completely as the engine warms up. You may also notice the sound is more prevalent at idle.
Most commonly, its caused by a fuel pump that`s not working. The fuel pump fuse may have blown, or the fuel pump itself will need to be replaced. Alternatively, this problem could be caused by a leak in the fuel lines, clogged fuel injectors or a bad fuel pressure regulator.
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.
When the timing belt starts to wear out, it may create a ticking sound inside the motor. This warning sign may also be an indication of low oil pressure or the engine not having the proper amount of lubrication.
Most Jeeps that have a ticking sound coming from the engine bay will be internal and related to the valve train. The valve train will include the camshaft, rocker arms, lifters, push rods, and other cylinder head components.
The most common reasons a Toyota Corolla engine makes a ticking noise are low oil level or pressure, an issue with the ignition system, or an exhaust leak.
Dirty Oil Deposits
This is the number two reason for lifter tick sounds coming from the top half of the engine and one that has the least economical impact to correct.
It is strongly advised to only drive with faulty lifters for a short distance ranging a maximum of 100 miles, and that should be exclusively to reach an experienced mechanic who can address the issue. Attempting any more mileage than this could put you at risk of further damage and costly potential repair bills.
Failure rates are low for the first 75,000 miles or so, but after that, the rate of failure increases dramatically, with the majority occurring around the 125,000-mile mark.
One common culprit for this problem is the crankshaft position sensor, which measures the position and speed of the crankshaft. The computer uses the information from this sensor to know when to fire the spark plugs. If the sensor isn`t working, the spark plugs won`t fire, keeping the engine from starting.
There is a rattling sound. A lax timing chain, or worse, a broken timing chain with loose parts within the engine, will produce a rattling sound when your car is idling. This rattling sound is typically most prominent while the engine heats up and disappears after some time.
Low oil pressure might be the cause of those ticking sounds. When vital engine components don`t get adequate lubrication, it might cause other problems, and the engine starts to make these noises. A broken valve train component, such as lifters or cam followers, can also cause ticking, tapping, or clicking sounds.
You should hear steady, consistent clicking as the injector cycles, indicating proper function. No noise, intermittent clicking, or a difference with other cylinders likely means you have a bad fuel injector that needs to be cleaned, repaired or replaced.
Adding more oil will make the noise go away, but it won`t solve the underlying cause of the noisy engine – the oil leak.
The cost of a lifter replacement including parts and labor can often be steep, ranging in the $1,000 to $2,000 range. However, this price will vary depending on your car`s make, model, and year and the rates of the shop you use.
Does synthetic oil cause engine noise?” No. It simply makes the engine noise more apparent. When you use the conventional oil, it will tend to stick to your pistons more completely.
Wrong Oil Filter
Replacing the filter with the wrong one can decrease and sometimes increase the oil pressures through the pump which can cause abnormalities in the engine performance. A decreased oil pressure however is what primarily causes the engine components to make the ticking noise.
Tick increases speed with increase of rpm.
