Knocking from the engine
I can hear a strong knocking from my engine. I think it could possibly be a pushrod or rocker arm. The engine idles out with the knocking.
Experienced mechanics share their insights in answering this question :
Although it is unlikely to be the cause, I would recommend checking your engine oil level. If your oil level is low, the engine will not be lubricated sufficiently enough to function properly and will therefore make knocking sounds as the metal engine parts come in contact with one another. If the oil level is at the specified level, I would recommend having an engine inspection performed by an engine diagnostics professional. It is possible that your engine may have suffered internal damage and may require replacement of valves, camshafts, lifters, and/or other internal engine parts. Only a thorough engine inspection will reveal the true causes of this issue.
How to Identify and Fix Common car Problems ?

Older engines can have worn-out crankshaft and connecting rod bearings, which cause a knocking sound when the engine is idling. Knocking can also occur when the engine is under a load, such as when you put the transmission in gear or climb a hill.
The most common reasons a Dodge Nitro engine makes a ticking noise are low oil level or pressure, an issue with the ignition system, or an exhaust leak.
One of the most common causes of engine knocking is low oil. If your car has been using more oil than usual, it`s a good idea to top it off. You can also try using a higher-quality oil, as this can help reduce engine wear. It`s important to regularly change your oil because dirty oil can also cause knocking.
Knocking can damage the surface of the piston, the cylinder walls or the crankshaft bearings, all of which are expensive to repair. Modern computer-controlled injection systems can correct your fuel mixture to prevent knocking, but at the cost of engine performance.
If it is a rod knock yes, you will hear it. If something has come loose inside the timing cover, then yes you will hear it.
An engine tick is a tapping or knocking noise you hear when the engine is running. Generally, engine ticks are a sign that something is not expected in your engine. They often occur because of a lack of lubrication, which can create a potential for significant engine problems.
the purge valve on your car allows fuel vapors to be burned by the engine for emissions purposes. this valve will make a ticking noise at times. likewise, positive crankcase ventilation (pcv) valves can tick or rattle at idle.
If you hear a light knocking or pounding sound, the noise can usually be traced back to your connecting rods. This sound is often most noticeable when the engine is at an even rpm–not accelerating or decelerating–and is often caused by a worn bearing or crankpin, misaligned connecting rod, or lack of oil.
If you start to notice rod knock, this isn`t a problem that will just resolve itself—you must take immediate action and replace the rod bearing while also fixing any other parts associated with the sound. If you do not take action quickly enough, you might need to replace the engine entirely.
Knocking can cause overheating of the spark-plug points, erosion of the combustion chamber surface, and rough, inefficient operation.
If the ECU or knock sensor is going bad, they will not be able to process the data from the combustion chamber and correct any detonation issues. This can make your engine knock.
Once an engine starts to knock, the rod can fracture without warning. It could be the next time you start it in your driveway, or it could keep going for six months. Eventually though, the engine will blow and you`ll be stranded somewhere.
Adding more oil will make the noise go away, but it won`t solve the underlying cause of the noisy engine – the oil leak.
Damaged CV joint: The most common cause of a clicking or popping sound from the wheels is a broken CV joint. The CV joints, which stand for Constant Velocity, are essentially the wrists of your vehicle`s steering system.
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.
A low oil level can cause engine ticking noises as valvetrain components aren`t getting the proper lubrication and start to get noisy. If you hear a tick coming from your motor, check the oil level immediately.

If the valve doesn`t open and close on schedule, or if any part of the system clogs, the result can be a rough idle, sluggish acceleration or increased oil consumption. Rough idling is commonly caused by bad spark plugs, so problems with the PCV valve are often misdiagnosed.

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.

knocking in my engine
ANSWER : I’m assuming the truck has the 5.9ltr Cummins engine. While I cannot say if the engine is "shot" without looking it over myself, this engine has a 12 quart capacity. Being low 5 quarts is nearly 50% low on oil. That certainly could have caused some damage internally. If there are no oil leaks present to justify a 5 quart loss, then a compression test should be performed to determine if the engine is burning oil. As for the knocking noise, the cause might be best determined by whichever technician you choose to inspect the engine. It can very well be a connecting rod causing the noise.

How do you replace the rear & side engine mounts without lifting out the engine? & how do you lift the engine out?
ANSWER : Hi…thank you for your questions. If required in the application, a portable engine support bar is used to support an engine during mount replacement. The support bar has lifting capability as well so that the mount can be unloaded and removed. If a particular repair application requires a "crane" (complete engine removal for instance), such are portable these days in any event. With regard to the exhaust system repair, mechanics use ramps to gain access. Six ton portable jack stands will safely support a car two feet into the air which provides more than enough access to repair or replace any exhaust system component. If you desire replacement of the mounts, please refer to YourMechanic’s motor mount replacement service page. For exhaust leaks, please use the exhaust system inspection/repair page page. Once on each of those service pages, if you click on "Get a Quote" and enter your vehicle information (year, make, model) you can obtain cost info and schedule the service. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.

Noise in the frontal area off the engine near the fan
ANSWER : Hello, thank you for writing in. There must be more diagnostic work and testing done to determine what the issue is. Without a drive or timing belt, the engine would either not run at all, or perform very poorly. This does not mean that an inspection of the timing belt/chain should not be done. There are other components in the timing belt system that can become damaged and cause issues. The valve and lifter consideration is valid, and can be inspected visually with some time and energy. Unfortunately you may also have crankshaft end play or a bad camshaft bearing. Use the location of the sound to help you determine what to check into first. One by one, check into the systems in that area until you find the culprit. For more help resolving the noise, contact our service department.

Engine malfunction light, reduced engine power, engine powered down
ANSWER : Hi there. There are a lot of things that can cause this on your 2012 BMW M5. I usually start by scanning the computer for codes to see what comes up. If there are not codes then I load test the alternator and the battery to see if they are failing. Low voltage in the electrical system will cause this. If that is fine, then it is usually caused by a failing throttle body. I have seen a lot of these fail due to the motors in them hanging up. If the problem is only happening intermittently, this can make the issue hard to duplicate, but you can still have tests done on the car. If you are going to have this fixed, consider YourMechanic, as a certified mechanic can come to your home or office to test the vehicle and diagnose the Engine Malfunction Light.

I have an engine knock and my oil pressure guage is reading high, then stops shortly after starting to drive.
ANSWER : Hello,
You may want to inspect your oil pump to see if it may not be causing the problem. If it is not pumping or circulating oil properly, it may also cause this type of increase in oil pressure that may be sporadic as you describe. When you first start the engine, the oil pump needs to work a bit harder than normal at first the get the oil circulated through the motor to all of the places it needs to go as the oil is much thicker when it is cold. As the engine warms up, the oil becomes thinner and flows a bit easier, which may be what causes the pressure to come back down once it is warmed up. Please feel free to reach out to us here at YourMechanic or schedule an appointment to have one of our qualified mechanics come to your location to diagnose and inspect your truck.
