Intermittent ticking sound from front of engine

My new Nissan Titan (2017) with 5.6 L V8 gas engine and 7 sp transmission has an intermittent ticking sound coming from front of engine. My truck has only 5,000 kms on it. No ticking at startup and sometimes after you drive it a bit and then let it idle you hear the ticking. When taken to Nissan dealership (service manager/technician have heard the ticking) and by the time they get to the truck to and try and identify where exactly the ticking is coming from, the ticking has stopped. From what the service manager has heard, he is certain that it isn't coming from the engine. They have chec
Experienced mechanics share their insights in answering this question :
If the ticking sound seems to be dependent on temperature, I might suggest taking a look for an exhaust leak somewhere. Small exhaust leaks will normally begin when cold and diminish as the engine warms, but in my experience, I have seen exhaust manifolds and pipe connections that will respond in the opposite, like you are describing. I’m not sure if this is the case in your situation, but it is another credible place to look.

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.
The most common reasons a Nissan Titan engine makes a ticking noise are low oil level or pressure, an issue with the ignition system, or an exhaust leak. Search our network of RepairPal Certified shops near you to speak with a technician about your issue.
One of the most common sources of a ticking or clicking noise in the engine is in the valvetrain. The valvetrain includes all the parts necessary to control the intake and expulsion of gases in the engines combustion chamber.
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. The noise can go away once the parts are properly lubricated.
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.
A ticking lifter is usually an indication there is a problem with your oil, especially as your car ages. It`s possible the lifters themselves are simply worn. If you have a much older car you`ve been driving for a long time, it is more likely this is the problem.
One of the first abnormal noises produced by an engine low on oil is often that of a ticking nature. This occurs as an engine`s critical top-end components are starved for vital lubrication. If oil is not quickly added or a complete oil change done, significant engine damage can occur as a result.
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 most obvious symptom of a faulty hydraulic lifter is the noise it creates in your car`s engine. You can usually distinguish the faulty lifter by the distinct sound. Instead of a knock or ping, a faulty hydraulic lifter will usually make a sound more reminiscent of a tapping sound.
A failing timing belt can produce a well-known “ticking” noise that will emanate from your engine. This ticking noise can also be a sign of low oil pressure within your engine, if you check your oil and your level is within a normal range, consult your mechanic to inspect your timing belt.
A lifter tick is caused when the push rod or camshaft doesn`t make continuous contact with the lifters. This can be because the lifter has become worn out, as is the case usually with hydraulic lifters, or the valve has come out of adjustment.
If there are eight cylinders, it costs a total of $1600 to $2,200; six cylinders cost around $1100 to $1,750, while four cylinders cost $900 to $1,500. A skilled mechanic would charge you $60-$150 per hour to replace the faulty engine lifters.
Lifter Ticking

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.

bad spark plugs or wires

spark plugs seal off each cylinder, so if one cracks or gets loose, you`ll hear a ticking noise. this is a common problem after diy tune-ups. your first step is a visual inspection of the spark plugs with the engine off and cool.

The Causes of Engine Ticking

Fuel injectors are small electrical valves that make clicking and ticking sounds when quickly opening and closing at idle. Ticking of the injectors is normal and you can drive without any worry.

Intermittent ticking sound from front of engine
ANSWER : If the ticking sound seems to be dependent on temperature, I might suggest taking a look for an exhaust leak somewhere. Small exhaust leaks will normally begin when cold and diminish as the engine warms, but in my experience, I have seen exhaust manifolds and pipe connections that will respond in the opposite, like you are describing. I’m not sure if this is the case in your situation, but it is another credible place to look.

Can front wheel drive car engine power rear wheel drive
ANSWER : Anything is possible with enough engineering. The changes you are looking at would take major structural changes and would definitely not be an easy job. You could possibly consult a manufacturing engineer to get more details on how this could actually be carried out and whether it would be feasible.

at a cold start there’s a ticking sound from under the hood until the car warms up.once the car is warm the ticking sound is gone
ANSWER : This noise is likely due to the engine wearing out over time. It is possible that the wrong viscocity of oil was used at the last oil change. I would recommend ensuring that the correct oil was used last time the oil was changed. You can do this by checking your records or if you chage it yourself you may know if the oil is correct or not. If the oil is the correct viscosity, I would recommend using Lucas oil stabilizer as this product was made specifically to deal with this exact issue. You can find it at the local auto parts store.

My engine has a ticking knocking type of sound. It runs fine not buring oil or losing coolent. Sounds like the valves taping
ANSWER : On a 1998 engine with 147,000 miles, the noise could come from anywhere. I typically check the engine oil level when cool to verify it is correct. Then, I run the engine for 5 minutes, shut it off, and check the engine oil level again.

If after running it for a short time and the engine oil level is lower, then it is likely you have a sludge build-up in your oil return passages preventing oil from draining back to the oil pan. If so, maybe an engine oil flush is in order. At the mileage, sometimes an oil flush may do harm to your piston rings or may help. You never really know.

If the oil level is correct after running the engine, you should have an oil pressure gauge connected to the engine to verify that it is within specifications to factory numbers to verify the oil pump is working properly.

An engine tapping noise could be anything from connecting rods on the crankshaft to an engine valve lifter. If the noise is a knock-knock in a repetitive motion at a slow speed, I would suspect lower engine problem, like a connecting rod (which requires a complete engine rebuild). If the noise is at a higher frequency, then I would think you have a valve issue which could be repaired at a much lower cost.

Based upon mileage, the feeling of how the engine runs, engine codes (if any), and an unknown level of maintenance, it is difficult to determine the exact issue. You may need an engine repair, a new engine, more oil, an oil pump, or just live with it. I’d have a certified mechanic take a look at it to diagnose and fix the sound that’s coming from your engine.

Loss of power, weird sounds from the engine and hissing sound from throttle body, and a code P1346 1999 Lexus IS200
ANSWER : Hello – the P1346 problem code you have indicates a camshaft timing problem (variable valve timing to be specific), and is at least part of the cause of low power. The cams are out of time, relative to the crankshaft. The hissing sound from the throttle body area is likely an air leak from a hose, or some other portion of the air intake. The tapping sound could be a variety of faults, worn/leaking hydraulic valve lifter, worn cam, piston slap, etc. I recommend a timing belt service to get the cams properly timed, performed by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, and give you an accurate assessment of damage and cost estimate for repairs.

When I start my car it sounds like a muffler news up front right below the engine what is that or can you help

This can be determined by a visual inspection and if you desire such an inspection please request an engine noise diagnostic – suspected exhaust leak/loose mount. If you request that inspection, a certified Mechanic, dispatched by YourMechanic right to your location, will get this taken care of for you. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.

Engine cooling fan isn’t working. Steam and liquid is coming out of a black pipe in front of the engine and temperature gauge spiked to H
ANSWER : Hey there. If the engine electric cooling fan is not turning on, the reason has to be determined. The fault could be due to a bad electric motor, a bad coolant temperature sensor, a failed relay, or even a wiring/fuse problem.

To resolve cooling system problems, one typically starts with a cooling system diagnostic. If the diagnostic establishes that the electric fan motor itself is bad, replacement of the fan motor is a straightforward procedure that is done by a mobile professional.

The leak and steam that you are seeing might be a consequence of the engine overheating because if the fan is not operating not enough air will flow though the radiator at low vehicle speeds. Once the fan is restored, the rest of the cooling system can be checked out to be sure that there are no actual leaks and that your car engine’s operating temperature is within normal limits. If you want to have this taken care of, a certified professional from YourMechanic can come to your car’s location to diagnose the overheating issue and assist with repairs.

Reduce engine power / check engine light is on
ANSWER : Hi there. Most of the time, reduced engine power is caused by a restriction of fuel, or the throttle body’s inability to efficiently mix air and fuel. This could be caused by a failing mass air flow sensor, EGR valve or other fuel system components. Since the check engine light is on, you should have a professional mechanic complete an inspection at your location to determine what codes are stored and which components require repair. This should resolve your issue.
